According to the Tire Industry Association (TIA), routine maintenance of valve-stem mounted sensors should be performed every time a tire is repaired or replaced. This maintenance involves disassembling the sensor and replacing a few key components (gasket, valve core, valve nut and valve cap). This will help ensure a proper air tight seal and clean away any corrosion that may have built up between services. TPMS sensors are battery operated with a life range of 4-10 years. Once the battery has expired the whole sensor must be replaced. TPMS sensors are produced by several different manufacturers and may use different radio frequencies, so care must be taken to select the appropriate sensor for the specific vehicle being serviced.Top
This time of year, we tend to see extreme temperature drops. In fact, weather experts confirm another polar vortex is set to return this week with arctic blasts expected to hit everyone east of the Rockies. While we can bundle up with extra layers, our cars are left to fight the elements. Cold temperatures can immediately impact your tire pressure. Keep an eye for the symbol to the right – these are common alerts on your dashboard that help to keep you informed of your vehicle’s condition. If you see this indicator, you should take swift action to check and correct your tire’s air pressure.
The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire’s inflation pressure will change by about 1 psi (up with higher temperatures and down with lower). In other words, if it were 40 degrees yesterday and -2 degrees today, you may experience a 4-5 psi loss in tire pressure. This may be enough to activate your low air pressure light.
Low air pressure should not be taken lightly
Not only is driving around with low tire pressure dangerous, it can damage your tires. It puts added stress on the sidewall which may cause them to wear quicker. Your goal should be to drive safely and to extend the life of your tires by maintaining proper tire pressure. You should also check the air pressure of your spare tire – so it’s ready if you need it. As always, if you have questions – please contact the nearest Dunn Tire store.
As we welcome in a New Year, many people are focused on keeping resolutions that will improve or simplify their life for the months ahead. Perhaps the most obvious resolution is car care maintenance. Vehicles can run a long time with the proper care. A car built in the last decade has a good chance of running well up to 150,000 miles. People want to maximize their car investment and get a good return. In fact, according to an annual study by IHS Automotive “the average age of vehicles on U.S. roads has hit a plateau of about 11.4 years.” At the same time, the number of vehicles on the road reached a record level of almost 253 million.
Basic car maintenance includes oil changes, tire rotations, tire alignment, checking tire pressure and visually inspecting the tread depth for uneven wear or damage. Not only can this help minimize the likelihood of major repairs – it’s required to keep tire warranties valid.
As we discussed in a recent article, treadwear warranties on replacement tires are offered by most major tire manufacturers. The goal is to help protect consumers in the case of significant premature tire wear. To maintain the warranty policy, the consumer will need to prove that the tires were properly inflated, aligned and rotated. The interval most vehicle and tire makers recommend for tire rotation is every 5,000 to 8,000 miles. Other vehicle repairs (or replacement parts) may include suspension or brakes as necessary to keep the tires functioning properly.
If the tires have been properly maintained, all four tires should wear uniformly at the same rate. If the worn appearance indicates the tires were not appropriately maintained, the tire manufacturer may not honor the treadwear warranty.
Vehicles that have routine scheduled maintenance last longer, are safer and have less incurred repair costs over time than vehicles that are not serviced regularly. Make your resolution to keep your car running at tip top shape with basic car care. Contact the nearest Dunn Tire for assistance.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.

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
