Excessive Wear In The Center
Causes- This tread pattern occurs when the tire has been over-inflated for a long time. Excessive tire pressure and high speeds pushes the center of the tire out causing the center to carry most of the vehicle weight.
Driving at highway speeds with over-inflated tires compounds the problem, and seriously over-inflated tires can burst as they heat up from highway use.
Solution- Adjust your tire pressure to the correct PSI rating found on the side of the tire.
Remember that if you do not drive your car fully loaded with passengers or cargo, you can inflate your tires to three or four pounds less air than the maximum PSI rating. The PSI rating on your tire is the maximum PSI. This means that if your car is fully loaded with your vehicles maximum carrying capacity, your tire should be inflated to their maximum PSI. However, most people travel back and forth to work by themselves and rarely fill the car’s seats with passengers or cargo unless going on a trip.
Running your tires just under maximum PSI will help your car handle better and give you improved traction, especially on wet or icy roads. Don’t let your tire pressure drop below 5 pounds less than the recommended PSI rating or your car’s fuel economy and performance will suffer.
Excessive Tread Wear On Outer Edges Of Tread with Bulging Sidewalls.
Causes- This occurs when the tire has been under inflated for a long time. Low tire pressure causes the weight of the vehicle to be supported by the sidewalls more than the center.
Over time, this will wear away the outer tread and will cause the tires to run hot during highway driving. The car will feel spongy and seriously under-inflated tires can even cause the vehicle to lose control over large dips in the road or around sharp high-speed curves.
If you have ever had one of your car’s tires plugged from having a nail or puncher repaired then, that tire will have to be checked more frequently. Tire plugs can dry out over time and develop a slow leak. Over time, you may have to have the plug replaced with a new one.
Solution – Adjust your tire pressure to the correct PSI rating found on the side of the tire. Again you can still run your tires inflated just below the recommended PSI by three or four pounds to improve traction and handling if vehicle’s vehicle is not loaded to the maximum carrying capacity but stay within that range. Tires that are filled correctly will last longer, run safer and give you the best gas economy.
Tip- You should purchase a good tire gauge from your auto parts store and keep it in your glove box. If you do not know how to use one, the sales clerk can demonstrate it for you. Most tire dealers will recommend checking your tire pressure every time you fill up the gas tank, but most people will not go to this extreme.
We recommend that you check your tire pressure at least once a month to maintain proper tire pressure and good fuel economy. You should also check your tire pressure before going on any trips where you will be carrying more weight with passengers and cargo. This is a time when inflating your tires to the maximum PSI is recommended.
