Why would one tire wear more than the others?
Why would one tire wear more than the others?
There are a number of different issues that can result in one tire wearing faster than the other three: Improper air pressure in one tire: Tires are designed to have a specific level of air pressure in them. If they are under-inflated, the outside of the wheels can wear too much, and the tire is susceptible to cupping.
What causes bad tire wear on both sides?
I’m getting bad outside tire wear on both sides in the REAR. That tire appears to be flat-out worn out and possibly was run underinflated a bit. Not only are the shoulders worn, but it appears that the center is down to wear bars. How many miles have those tires been on road? How old are the tires?
What causes a steer tire to wear the shoulders?
Steer tires tend to wear the shoulders where drive tires tend to wear the center – and if the front camber is bad, the wear won’t be even. (I think a 4 Runner has a solid rear axle, so I doubt that there is a camber problem in the rear.)
Can a wear problem with a new tire reverse itself?
If you have a wear problem with new tires because of alignment or parts, you might not notice the uneven wear and you correct the problem but the uneven wear doesn’t reverse itself . There may be only 2/32 difference between the rest of the tire and that edge.
How can I tell if my rear tire is worn out?
If all this wear occurred w/the tire on the rear, the wheel must be slightly tilted out at the top, the top sticks out further than the bottom in other words. A bubble level with some spacers against the top and bottom of the rim might demonstrate this tilt if you want to become an amateur scientist.

What can a tire wear pattern tell you?
A tire can tell you a lot about a suspension. Most specifically, it can tell you if the angles, inflation and components are within specification. Here are the most common wear patterns and what causes them. Tire wear in the center of the tread pattern tells you that the inflation patterns are too high.
What causes a negative camber tire to wear?
With negative camber, the top of the wheels are leaning inward (again, by design) which lean will tend to wear the inside tread of the tire, just as you are observing. Regular rotation of the tires, every 6,000 miles, tends to minimize that effect.
