# Tire wear in middle of both rear tires

I got 2 new tires about 9 months ago and 2 more new tires about 6 months ago. I had an alignment done when i put the second set of tires on. I noticed first my drivers rear tire was wearing in the middle. Not sure exactly when I first noticed wear. Now my passenger rear tire is wearing in the middle. Each time I took the car in, they checked the air. From the beginning they said that my rear struts were worn. They also said that the struts are causing the tire wear.

Both front tires have no excessive wear.

I took the car in to another mechanic to get my check engine light turned off. He said that the wear in the middle of the tires is not from the struts, but from over inflation.
Two different tire shops have checked the air in the tires. Now I'm confused.

Also,
Is it safe to drive with the rear tires smooth in the middle?

Thank you,
Gary

If the wear is exactly even in the middle, it is from overinflated tires. If it has patches of wear, even in the center but not consistent, it is because it is misaligned or something is loose where the tire gets held( the struts or the bushings)

Problem is with over inflating the tires,causing middle tread wear,as long as you have more the 3/32 tread wear in the middle than you are ok.always set tire pressure when cold at around 33psi,check tire inflation sticker on dar jam for exact tire pressure

Over inflation is the culprit here. Most tire shop technicans do not know to compensate for heated air in the tires when checking pressure. One way to combat this is with nitrogen inflation, an inert gas readily avalible at tire shops. Not dangerous and does not expand or contract with temperature changes.

Possibly have bad rear struts or other rear suspension wear or damage. Check the Toe In/Toe out are within specs.

### Back tire inner wear problem

Might have a bent axle or

This happens when rear struts are replaced.

### 2005 RAV4 rear tire uneven wear

You need to have a four wheel alignment done. Keep in mind once the tires start to wear like you have they will continue to wear that way even after the align is done.

### 1997 cavalier, both rear tires wearing on the outside 1/2 of the tires. What would the probable culprit be? The car has 97k miles on it...

if you don`t rotate the tires this can cause abnormal tire wear.but with tire wear on the outer 1/2 of the tire indicates either the camber setting is off or you could have bad rear springs changing the ride height of the car causing the change in camber.to find out you would have to have a 4 wheel alignment done to check rear alignment readings.if the springs are worn then the ride height can be checked with a tape measure and compared to specs,if off then the springs should be changed along with the rear shocks.

### I Had the tires rotated on my 2008 mazda cx9 at 13,000 miles in our local shop here,then i noticed a humming sound coming from front of vehicle and only when it approaches 50 to 55 mph,could it possibly be...

The noise is most likely caused by the different wear pattern on the tire that came from the rear of the car. The difference in the alignment between the front and rear suspension systems causes the tires to wear accordingly. It will take some time for the tires to wear in to their new environment. The noise should go away gradually. You should also check your tire pressure to make sure you don't have an improperly inflated tire.

Definately an alignment issue. May even be something damaged. Need to find out as you may have a pre-existing condition that you can take back to where you purchsed this vehicle.

### Alignment in 2007 Acura TL

It depends on what kind of uneven wear you are talking about if the front is wearing on the inside or outside on one side or both yes you need an alignment but if front tires are are worn about the same on the inside and outside of the tire that is not uncommon it is better to rotate the tires about every 5,000-7,000 and keep the air close to maximum as they will get you better gas mileage and wear better example if the tire says a maximum of 44psi put about 38-40psi when tires are cold and havent been ran.If those are the original tires and you have 49,000 on your car then you don't need an alignment.

### Bought new tires about 4 to 6 months ago. steel belts are comeing from the inside of tire. car is rideing on the inside of the tire. why

The alignment is out. With the picture below, you most likely have a " TOE IN" problem. The 2 front tires facing inwards will cause the inside tire tread to wear out faster than normal.
