Re: Both rear tires are wearing on the inside.
1. Tires were rotated not long ago, so they were in the front. Alignment problem.
2. Some vehicles do have rear adjustment for Alignments. Basically like the front, the rear end can be adjusted also. They call this a 4-wheel alignment. The alignments that are adjustable only in the front is called a thrust alignment.

Under inflation. When the tire doesn't have enough air pressure, the center tends to be pushed up from the road. Thus causing outer wear on both sides. alignment problems cause wear on one side or the other. Over inflation causes the center of the tire to wear .
Preventing tire wear is about regular maintainence to your vehicle.
You should rotate your tires every 5,000 miles , and keep
your tire pressure at factory pressures as indicated by the tag
inside the drivers door column.
Alignment is another factor in tire wear , look at your tires carefully .
Look for any unusual wear , especally on the inside of the tires,
as this is usually the most troublesome spot.
As vehicles age , the springs lose their tension to a degree.
This causes a problem in the tire angle called "camber".
The vehicles wheels are tilted inward at the top.
Excessive negative camber will wear the inside of the tire.
Most vehicles can have this corrected by properly aligning
the vehicle .
Another wear problem can be caused by the toe adjustment
being out of specifications .
This is the most destructive angle to tires , it the same angle you use to steer the vehicle left and right .
It normally causes inner and outer tire edges to wear rough in
one direction smooth in another while rubbing your hand around the
Both these angles can be corrected by a professional alignment .
Be sure the technician inspects your front end for any worn parts,
as aligning it with them is a waste of money and time .
Always ask for a before and after printout of your alignment.
I replaced the rear struts, when removing i discovered one was totally bad, they didn't seem bad from testing and recovered quickly when pushing on the bumper, but were bad. after replacing my rear tire wear is even after 5k miles. mine were wearing from inside to outside too.
Strange. Has anyone checked the front end alignment on a rack ? Usually when the tires wear on the inside edges the camber is off and the tires are running on the inside edge more than the outside. Or the front suspension is too low or heavy.
you normally only get that sort of wear on the front and is caused by the steering being out of track the only thing i could suggest is have a laser track done at your local tyre shop and get them to ballane it all four tyres while they have it .ill look further into it for you my email [email protected]
Unless there is noise or play when cornering sharply at low speeds (parking), the CV joint / boot is still ok. The joint does need grease in there and the rubber boot fitted properly very soon.
As the suspension is set, the axle does little more than provide drive. It doesn't affect toe-in or camber angle.
Camber angle (vertical tilt inwards) is a product of the suspension design, and often cannot be altered.
Weak front springs can also throw this angle out, as the vehicle sits too low.
Toe-in (forward point angle) can and must be set accurately, or you will skid about in wet weather depending which tyre grips more.
What is most important to you, is the tyre design, tread width and outer radius. Also the tyre pressures MUST be mid limit when cold on the front - otherwise excess wear will result.
Having tyres with a large contact area that are too rigid on the front will increase wear to the insides.
Also, it is good practice to rotate the tyres to even-out wear. Usually front tyres move to rear axle, and rears swap sides to front axle. If wear is uneven, pop them off and turn around before refitting. Some tyres you cannot do this with.
If you choose a tyre with a harder tread compound, or ones with "C" at the end of the code, these will again last a lot longer.
