Commercial Tire Dealers Playing Key Role in Keeping Transport Moving

from Tire Business Magazine...

CUYAHOGA FALLS, Ohio — By their very nature as service providers to the nation's trucking industry, commercial tire dealers throughout North America are less affected by the COVID-19 pandemic than their retail counterparts, but that's not to say business is booming.

"Anyone who's in the (commercial) tire business recognizes how lucky they are to be deemed an 'essential' business," Walt Dealtry, CEO of Bethlehem, Pa.-based Service Tire Truck Centers said in an interview with Tire Business, drawing a contrast to those in other industry segments not so fortunate. Mr. Dealtry said the impact on STTC, which operates 46 outlets in eight Eastern seaboard states, varies from state to state due to local pandemic-control measures, but overall the dealership has been able to keep them all open if in some cases with reduced hours. He noted March actually was a good month in part because some fleet customers placed extra orders in order to stockpile tires as a precaution. STTC was "heavy" on inventory, though, so this doesn't pose a supply problem, he said, at least not yet.

"Headwinds are coming in April, however," he cautioned, noting that STTC has trimmed employment some, a move that affected primarily part-time workers and more recent hires. Mr. Dealtry said the mechanical maintenance and repair side of his business has been a bright spot, while at the same time STTC has had to postpone work on some facility expansions due to the of stay-at-home orders. Workers at STTC's 10 retread plants agreed to scale back to 32-hour work weeks in order to spread the workload around and stave off layoffs.

Jim Parkhouse, owner of Parkhouse Tire Inc. in southern California, echoed Mr. Dealtry's comments regarding the effect of customers stocking up on tires as a precaution. Otherwise, business at the dealerships 12 outlets has held up because of the trucking sector's continued level of activity delivering goods to key sectors, he said. The dealership has eliminated all overtime work and is planning to move its retread plants to four-day workweeks, in order to avoid layoffs. "We want to keep good employees," he said, noting this move is designed to keep them around long-term as well. "We don't want to have to start over when this passes looking for qualified workers."

At Wilkes-Barre, Pa.-based McCarthy Tire Service, commercial-related activity has been steady, President John McCarthy said, but retail business has been down about 50%. He noted that many of the dealership's locations have seen increased demand from trash-hauling companies buying tires to maintain their inventory. He also said agricultural was doing well and construction business was OK as quarries in most states still are operating. McCarthy Tire Service employs 1,300 at 60 locations spread from upstate New York down to South Carolina. "We've never seen anything like this. This hits everybody," he said. "We've put protocols in place for different situations a while back, like in case of bad weather, so we are adjusting those plans to fit this situation."

Those at the company who are able to work from home are doing so, Mr. McCarthy said. The company has furloughed about 20% of its workforce in a variety of departments, though not the service department, "because they have been pretty busy." McCarthy Tire shops are following Centers for Disease Control and Prevention (CDC) guidelines.

It has stopped vendor visits and salesmen from making (face-to-face) sales calls and canceled most travel. The dealership is enforcing a six-foot distance between people and limiting the number of people in one area at a time. The company also has installed plexiglass at the front desks in the showrooms. Everyone is wearing gloves, and, at larger locations, employees' temperatures are being taken twice a day. Mr. McCarthy said he has been sending out daily emails to staff to keep them informed, help boost morale and promote positive thinking.

"Some people are scared," he said. "When we find out what worries them, we try to address it."

The Customer’s Voice

There's no shortage of news sources these days to keep business owners on their game, but the single most valuable source is always the customer. That's why we were so pleased to receive this customer review of our Columbus, OH Fleet Store operation recently.

"First and foremost I want to thank the entire staff here for how professional and courteous they are! The service here is outstanding compared to other tire and oil places. The staff here know what they are doing and do it right the first time. Just as it should be done! If you are looking for tires, service or anything semi truck related, check this place out before you go to a competitor. Prices and work are of upmost quality. Clean shop floors and nicely sized garages. I will only bring my truck to Shrader from now on! Thank you so much!"

Here are five good reasons why customer feedback is important:

1. Customer feedback improves products and services

When you initially introduce a new product, brand or service to market you probably have an idea about customer needs. Market research that you conduct before introduction gives you an idea if potential customers would be willing to buy it and also they can give you some tips on how you could improve it. However, only after your customers use your product or service you can learn about all the advantages, flaws and their actual experience. On top of that, their needs and expectations evolve with time.

2. Customer feedback helps you measure customer loyalty

Customer loyalty is a crucial factor that determines company’s financial performance. It is directly linked to many benefits, such as increased market share, lower costs, or higher revenue. There's no denying the close connection between customer loyalty and business performance. Therefore, there is no doubt that you want to make sure your clients are happy with your products and services. Naturally, the best way to find out if you meet their expectation is to get their opinions. 

3. Collecting customer feedback shows you value their opinions

By asking your clients for feedback you communicate that their opinion is important to you. You involve them in shaping your business so they feel more attached to your company. Listening to their voice helps you create stronger relations with them. This is the best way to gain valuable brand ambassadors who will spread positive word-of-mouth for you. And I am sure you are aware that their recommendations is probably the most effective and, at the same time, the cheapest way to acquire new customers and become more trustworthy in the eyes of your current and potential clients.

4. Customer feedback helps you create the best customer experience

Today’s marketing is heavily based on experiences people have with products, services and brands. They do not buy Apple products just because they are good. They want to demonstrate their status and affiliation to a particular group. They do not buy Nike clothes because they are durable. They buy courage to extend their boundaries. Therefore, if you focus on providing the best customer experience at every touchpoint clients will stay loyal to your brand. And naturally, the most effective way to give them amazing experience is asking them what they like about your service and what should be improved.

5. Customer feedback helps to improve customer retention

Loyal customers will stay with you. Unhappy customers will eventually find a better alternative and take their business elsewhere. Customer feedback helps you determine if your clients are satisfied with your service and detect areas where you should improve. By asking for opinions regularly, you  always have a finger on the pulse. Each time a dissatisfied customer expresses his disappointment, you have an immediate opportunity to react and find a solution to an issue. This is a perfect moment to win a client back and even increase his level of loyalty. 

At Shrader Tire & Oil, we've put the customer first for more than 72 years. Feedback like this is the payoff from the effort!

Michelin Unveils X-Ice Snow, its Next-Gen Winter Tire

NOTRE-DAME-DE-LA-MERCI, Quebec — When Group Michelin asked tire dealers and distributors what they wanted in the company's next winter tire, they said looks were everything.

The X-Ice Xi3, which debuted in 2012, was a very good tire — top ranked in its category with 4.5 out of 5 stars on — but they said it didn't look aggressive enough to sell in the showroom.

Though the focus group did say the new tire needed to maintain — and even improve upon — the performance of the X-Ice Xi3.

"Michelin listened to what they had to say and started with the look," Sabrina Garofalo, a marketing manager at Michelin North America (Canada) Inc., said. "Then they brought in all of the engineering to maximize the performance."

What Michelin designed in the X-Ice Snow is a tire that looks the part, performs well and should give buyers an extra season of use, the company said.

When Michelin started designing the X-Ice Snow, they conducted focus groups with tire distributors, retailers and end users to get feedback for how the company could build a more complete snow tire.

Better bite, especially in deep snow; less noise on the highway; improved grip on ice; a longer tread life; and a look that draws customers in were among the top requests.

Tire dealers said the tire needed to look more aggressive than its predecessor, the X-Ice Xi3. The reason, they said, was because the sales window for winter tires in North America is so short — around eight weeks — the tire needs to stand out if it's going to sell. Michelin did not disclose the price of the new tire, but indicated it will be slightly higher than that of the X-Ice Xi3.

TIA Determines Crumb Rubber Poses No Health Risks

The benefits of recycling scrap tires for crumb rubber has recently been under fire as some media reports maintain that recycled rubber could be harmful to people and the environment.

Crumb rubber is the name given to any material derived by reducing scrap tires or other rubber products into uniform granules. On average, between 10 to 12 pounds of crumb rubber can be derived from one passenger car tire. The granules, or crumb, is sold as feedstock for all different types of products, including asphalt for paving, and sport surfaces like children’s playgrounds, athletic tracks, and tennis courts.

The Tire Industry Association (TIA) has now weighed-in on the crumb rubber issue. TIA's Environmental Advisory Council (EAC) conducted extensive testing in the United States and overseas regarding the potential health and environmental effects. In every evaluation, researchers from the EAC determined that crumb rubber used in artificial turf or as a playground surface poses no significant health or environmental risk.

The full position statement can be viewed on the TIA website HERE.

Think Roadside Alligators are all Retreads? Think again.

Researchers investigate causes of truck tire debris, find 60% are virgin tires.

“There’s a public perception that if it’s a retread truck tire, it’s not as good,” says Oliver Page, assistant research scientist in the Transportation Safety Analysis Division. “That’s not true. What we were trying to do is see if retreads were overrepresented in samples collected, and if they were, whether the probable cause of failure was due to manufacture/process issues.”

86,000 pounds of fragments and casings were analyzed after being collected from major interstate routes in five different states with high commercial-trucking flows.

Overall, where tire status could be determined, original equipment actually accounted for 60 percent of the tire casings tested, whereas retreads accounted for 40 percent.

Analysis of the debris found that road hazards, such as hitting a curb or sustaining a nail puncture, were the most common cause of tire failure for 38 percent of the fragments and 36 percent of the casings. It was determined maintenance and operational issues accounted for 32 percent of the tire casing failures, while degradation from excessive heat was evident in the final 30 percent of the tire fragments examined.

For both casings and fragments, tire failure due to the retread manufacturing process was under 15 percent.

Going Green to Save Green

Recycling and Retreading Tires

Old tires have a knack for finding their ways to the side of the road or in scrap piles at many trucking fleets all over the United States. Often times we forget the value those tires may hold. This is why Shrader Tire & Oil offers the "Cash-4-Casings" program where we buy back your used tire casings for retreading purposes.

Retreads are significantly cheaper than new tires, and through Michelin MRT Retreads, we're able to achieve 90% tread life than that of virgin tires. This is a cost-effective way to keep your commercial trucking fleet on the road, all while being environmentally friendly and recycling used tires.

To learn more about Recycling & Retreading tires with Shrader, click HERE.


Recycling Oil

Many of us "do-it-yourselfers" have old milk jugs and buckets filled with waste oil in our garages that are just collecting dust and waiting to be disposed. Do you realize that used motor oil can still have a life after it leaves your engine? In fact, used motor oil can be refined and reformulated to meet API specifications. With a waste oil furnace, your used motor oil can also be treated as fuel to heat a garage.

So what can you do to be environmentally conscious? If you change your own oil, be certain that you take it to a collection center for recycling. Visit a recycling center near you. Some collection companies will even come out to your facility, collect the used oil, and then pay you! If you take your car or truck to your local service station, they are required to recycle the oil that they change.


Recycling Batteries

Batteries contain lead that is 97% recyclable, but each year millions of batteries are not recycled. Some are illegally disposed of in dumpsters, while others sit in garages, junk piles or storage sheds. Leaking acid from these old batteries create health and safety hazards to the environment. Because recycled lead costs less than freshly mined lead, recycling old batteries helps sustain lower costs for new batteries.

Since these battery cores contain harmful chemicals, be sure to always take precautions when handling them:

• Wear gloves and safety glasses
• Place battery cores on a sturdy surface to transport them (If the battery case is cracked or leaking make sure to place it in a plastic bag or leak proof container)
• Keep batteries upright and tightly secure before transporting
• Do not smoke near or expose batteries to an open flame

Allow Shrader to buy back your unwanted battery cores. Here is a list of our new batteries from EXIDE.

Improving Fuel Economy with Chevron Delo 400 XLE Syn-Blend 10W-30

Both owner operators and truck fleets alike are struggling with rising fuel costs as a major operating expense. This has led many in the transportation industry to seek cost saving solutions in their maintenance practices. With Chevron, Shrader recommends switching from conventional 15W-40 engine oil to a lower-viscosity product like Chevron Delo 400 XLE Syn-blend SAE 10W-30.

This product is formulated for use in modern on-highway, low emissions engines as well as older diesel engines. It also provides exceptional performance in modern off-highway engines where an SAE 10W-30 viscosity grade is recommended, including those adapted for future emissions standards in construction, agriculture, marine and mining applications.

Delo 400 XLE Syn-blend SAE 10W-30 shows up to 3.6 percent fuel economy improvement in short-haul, class 6 vehicles and up to 1 percent improvement in long-haul, class 8 trucks compared to SAE 15W-40 oil in SAE J1321 Fuel Consumption Tests. Depending on the fleet, the savings associated with these fuel economy improvements could equate to thousands of dollars a year.

Couple this with the ability to extend oil drain intervals and the savings for a fleet could be the difference between you and your competition. Testing run in a Volvo 13-liter engine showed drain intervals could be extended by more than 40% over the regular Volvo recommended drain interval.

An added bonus in addition to better fuel economy, Delo 400 XLE's low viscosity base stocks promote consistent engine starting for vehicles operating in sub-zero temperatures. 

If you’d like to know more about saving money with Chevron Delo 400 XLE Syn-blend SAE 10W-30, contact a Shrader Representative today. For more on Chevron Delo products, visit

Everything You Need To Know About DEF

What is DEF?
Diesel Exhaust Fluid (DEF) is a nontoxic solution of 67.5% purified water and 32.5% pure automotive grade urea that is API Certified and complies with ISO 22241-1. DEF is the key element of the Selective Catalytic Reduction (SCR) system used by most medium and heavy-duty diesel engine manufacturers to meet EPA 2010 regulations. When injected into the exhaust stream and passed over a catalyst, Diesel Exhaust Fluid helps convert NOx into nitrogen gas and water vapor – two harmless and natural components of the air we breathe.

A Brief History
The EPA began regulating greenhouse gases from mobile and stationary sources of air pollution under the Clean Air Act (CAA) for the first time on January 2, 2011. NOx reduction is necessary because it contributes to acid rain and smog, making it harmful to our health and our environment. Diesel engines are now required to meet these tighter NOx standards for the US market.

The SCR System
Selective Catalytic Reduction technology is the dominant system to meet these new standards by heavy-duty engine (Class 7-8 trucks) manufacturers. The SCR system works by injecting DEF directly into the exhaust upstream of a catalyst. There, DEF vaporizes and decomposes to form ammonia. The ammonia then works in conjunction with the SCR catalyst to break down NOx into harmless nitrogen and water.  

Drivers must be sure to not run out of DEF in an SCR equipped truck by monitoring the DEF gauge, as the truck will not run without it. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tank and cannot be mistaken as diesel.

DEF Storage
Quality control is very important in the handling and storage of DEF to ensure the SCR system stays functioning properly. DEF should always be stored in a cool, dry, well-ventilated area – preferably away from direct sunlight. Do not store diesel exhaust fluid in carbon steel, aluminum, copper, or zinc because it will corrode these metals. The recommended temperature range for storage is 12° - 86° F, but temporary exposure to warmer temperatures will not degrade its quality or performance. If DEF is stored at approximately 75°F, the shelf life should be two years long.

DEF dust can contaminate the fluid around the area where DEF is added to the system so be sure to keep this area clean and free of debris. It is crucial that the 32.5% urea solution remains at this ratio because it provides the lowest freezing point for DEF which is near 12°F. Additionally, SCR systems are calibrated to the 32.5 percentage. It is unlikely for DEF to freeze while a vehicle is running as the SCR technology heats the DEF tank and supply lines. DEF is more likely to freeze when the vehicle is not being operated, but the vehicle will start up and run as normal. Once the vehicle is started, the SCR system will melt the frozen DEF quickly and the vehicle will not be impacted. DO NOT ADD OTHER CHEMICALS TO KEEP DEF FROM FREEZING. If something is added, it can ruin the solution and may even damage SCR components. 

Equipment and Availability
An experienced DEF supplier, such as Shrader Tire & Oil understands important DEF issues and can be flexible in meeting your DEF needs. We have the expertise, regional supply and customized distribution solutions to help you achieve the right DEF supply strategy for your application.

Allow Shrader to assist you with a custom DEF solution for your fleet while reducing maintenance costs and creating less harmful emissions in the atmosphere. Shrader carries Victory Blue DEF which is API certified. We offer DEF in bulk, 330 gallon totes, 55 gallon drums, and 2.5 gallon jugs. Look to Shrader for DEF distribution equipment including hand pumps, reels, and electronically metered pumps.
