They are: Improper air pressure, lack of rotation, improper wheel alignment and worn out suspension parts. Improper air pressure will cause your tires to wear out prematurely. Under-inflated tires tend to show wear on the outside edges of the tread. Over-inflated tires show wear down the middle of the tread. Keeping your tires inflated correctly will help get you the mileage you expect from your tires. Not rotating your tires in a timely manner can cause two of your tires to wear faster than the other two.
However, we're pretty sure that all tire manufacturers are now recommending having the better tires on the rear. Not only will some retailers refuse to put new tires on the front when buying only two, we've even heard that putting new tires only in the front is illegal in some states though we were unable to verify the latter.
Why is this? Continental tire was kind enough to send the boss along with many others to their proving grounds in Uvalde, Texas, and they did a demonstration of this. It involved each participant driving around a circle at 50 mph. Each person drove two matching cars: one car had tires with more tread on the front, and the other car had tires with more tread on the back.
When they hit the water in the car with the better tires on the back, the front tires lost grip, the car wouldn't continue to turn and the car skidded straight ahead. On the other hand, when the participants hit the water in the car with the better tires on the front, the rear tires lost grip first, the rear end of the car started to come around, and some people even spun!
This type of situation can certainly happen in mountain driving, but the same thing can happen if you have to slam on the brakes or swerve. Therefore, there are two reasons why you would want the better tires on the rear. The obvious one is that many drivers are not used to controlling the car when the rear end comes around.
The other is that the majority of the safety equipment in most cars is designed for front impacts, and usually very little protects you from side or rear impacts. Therefore, for maximum safety, the better tires should be kept on the rear. If you drive a rear-wheel drive performance vehicle with a square tire setup , then regular, even, accelerated tire rotation protocols between front and rear axles can work to even out your tire wear situation.
If your tires are staggered, then minimizing rear tire wear comes down to maintaining proper inflation, alignment, and keeping that right foot in check. More details below. Under normal driving circumstances with a front-wheel drive vehicle passenger cars, minivans, etc.
Similar to the case of a rear-wheel drive performance vehicle, although not to the same extent, the front tires are called on to manage all the drivetrain forces in a front-wheel drive arrangement.
Front tire wear is further advanced because the front tires handle the bulk of the steering and braking forces. Tire rotation is the solution to even tire wear in a front-wheel drive vehicle. Most front-wheel drive passenger cars have a square tire setup, which allows for front to rear tire rotations. Check out knowing your tire pressure for guidance. Visit a tire shop for professional diagnosis and solutions.
If wear is advanced enough, all four tires should be replaced. Even if only the front or rear tires are expired, the remaining two tires might be worn to the point that replacement is advisable. Fitting two new, full tread depth tires could create a traction and handling imbalance with the older set.
Not maximizing the life of any tire is always regrettable, and feels like money down the drain, we get it. But in many uneven wear circumstances, replacing all four tires is the much better path in both the near- and long-term.
