There are a lot of questions and plenty of confusion regarding the replacement of tires on four-wheel drive (4WD) and all-wheel drive (AWD) vehicles. The most common question is “Do I really need to replace all four tires on my vehicle?” While the short answer is yes, we’d like to help explain the importance of this response.
Today’s AWD vehicles (also referred to as full-time four-wheel drive) are designed to monitor the wheel speed of the tires. The purpose is to detect any slippage that would activate portions of the all-wheel-drive system. This is accomplished by using differentials or viscous couplings (sometimes both) to allow for differing wheel speeds experienced when cornering or encountering loose pavement (and momentarily spinning a wheel). The ideal system will send precisely the right amount of torque to each wheel, which is the maximum torque that won’t cause that tire to slip.
When the circumferences of tires are not matched, the number of times the tire revolves per mile can vary by tire. This can occur when tires are replaced with no attention paid to the qualities that affect circumference like size, manufacturer, type and tread wear. Most differential systems are designed to allow short-term differences in wheel speeds when the vehicle turns a corner or spins a tire. If you use mismatched tires (tires of different size, type, manufacturer or tread depth), you may be forcing the differentials to operate at all times. This will lead to excessive heat and unnecessary wear on the differential, and may cause early failure.
As a policy, Dunn Tire will follow the tire replacement recommendations in each vehicle’s owner manual. We don’t create these guidelines, but they are in place for a reason. The top priorities are vehicle safety and optimal performance. We do not cut corners nor attempt to mislead customers.
As an example, let’s look at Subaru’s policy on tire replacement:
Tire Replacement. The wheels and tires are important and integral parts of your vehicle’s design; they cannot be changed arbitrarily. The tires fitted as standard equipment are optimally matched to the characteristics of the vehicle and were selected to give the best possible combination of running performance, ride comfort, and service life. It is essential for every tire to have a size and construction as well as a speed symbol and load index matching those shown on the tire placard. Using tires of a non-specified size detracts from controllability, ride comfort, braking performance and speedometer and odometer accuracy. It also creates incorrect body-to-tire clearances and inappropriately changes the vehicle’s ground clearance. All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment.
For safe vehicle operation, SUBARU recommends replacing all four tires at the same time. WARNING: All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, degree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to the vehicle’s power train. Use of different types or sizes of tires can also dangerously reduce controllability and braking performance and can lead to an accident. Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce controllability which can result in an accident.Top
Tire performance categories have been evolving for decades. With all the specialty tires and options, understanding these categories can be a little confusing. This is important information because you want the right tires that fit your vehicle and your driving style. For that reason, we’d like to better explain these tire categories. To start, let’s take a closer look at touring tires.
A basic definition of a touring tire is a tire designed with improved handling to provide a smooth, quiet, and comfortable ride. Designs range from high mileage S and T-rated tires to performance oriented V-rated designs. Touring tires generally include the following features and options:
- Slightly lower profile (from 70 to 55 series) and wider tread than an equivalent passenger tire for improved handling and stability
- The widest range of speed ratings (S, T, U, H and V)
- Numerous wear, handling, and ride quality tradeoffs (for example, the touring tires a minivan owner selects can be very different from the touring tires a BMW owner selects.)
- Predominantly all-season tread designs (a number of summer tires are available.)
- Tread patterns that emphasize performance blended with ride comfort and low noise
- Contemporary black sidewall styling (few touring designs offer a white sidewall finish.)
- Optional tread wear guarantees, which reduce as speed ratings increase
In general, a touring tire is one that is designed to provide the highest level of ride comfort and the most mileage rather than focusing primarily on performance attributes. Touring tires often have lower aspect ratios than standard tires, with many having larger rim diameters.
If you have any questions about touring tire models or if they are right for your vehicle, please feel free contact the nearest Dunn Tire store for assistance.Top
As temperatures reach 90F and above across the United States, drivers — particularly those planning a road trip — should ensure that their tires have the correct tire pressure. Hot temperatures and under-inflated tires are a dangerous combination. During the summer months, while vehicles are being driven at highway speeds, the heat and hot roadways contribute to the breakdown of tires and a greater likelihood for tire failure.
According to statistics from the National Automotive Sampling System (NASS) “about 36 percent of passenger cars and about 40 percent of light trucks had at least one tire that was at least 20 percent below the placard pressure.” That’s a staggering number of vehicles on the road with under-inflated tires.
When a tire is under-inflated, its sidewalls flex more and the air temperature inside the tire rises, increasing stress and the risk of failure. A significantly under-inflated tire loses lateral traction, increases a vehicles stopping distance and makes handling more difficult. It’s important to note that under-inflation also plays a role in crashes due to flat tires and blowouts.
Proper pressure is the most important part of maintaining a vehicle’s tires. Properly maintained tires improve the steering, stopping, traction and load carrying capability of vehicles and can improve gas mileage by 3.3 percent.
To prevent tire failure, NHTSA offers the following safety recommendations:
- Follow the recommended tire pressure in pounds-per-square-inch (PSI) for your vehicle. This information is found on the vehicle placard typically inside the car door and in the vehicle owner’s manual.
- Purchase a tire pressure gauge to keep in your vehicle. Tires lose one PSI every month, so it is important to check your tires monthly to ensure proper inflation.
- If your vehicle is equipped with tire pressure monitoring systems (TPMS), know where the TPMS warning is on your dashboard, and take action if you receive a warning.
- Check your vehicle owner’s manual for specific recommendations for tire replacement for your vehicle. Some vehicle manufacturers recommend six years, some tire manufacturers recommend 10 years as the maximum service life for tires, including spares.
- Monitor the tread on all tires on your vehicle. Tires with tread worn down to 2/32 of an inch or less are not safe and should be replaced.
- Look for treadwear indicators – raised sections spaced throughout the bottom of the tread grooves. When they appear it is time to replace your tires.
- Try the penny test. Place a penny in the tread of your tires with Lincoln’s head upside down and facing you. If you can see the top of Lincoln’s head, your tire has less than 2/32 of an inches of tread and you are ready for new tires.
- Remember that seat belts are your best defense in a crash.
Please drive safe this summer season – and as always, if you have any questions regarding tires, safety or maintenance, please contact the nearest Dunn Tire store.Top
The Official Dunn Tire Race Car will be on display next week at select Dunn Tire stores in the Buffalo, Rochester and Syracuse area. We invite everyone to come see this extraordinary car in person between 12–4pm at the following stores:
