The other day I knowticed that the outer edge of my pass tire was getting low on tread. Than today when I looked it was bald, but when I looked closer it was only bald in that section. The edge starts with low tread and gets worse as you go around till the bald spot, and than gets better as you come back around. The tires are old, so could it be the tires?

Edit---I did search but I didnt find anything

 

Yup, time for new tires............

 

Well I know that I need to change them but I didnt know if anyone knew what would cause this. Tires, steering, suspention, ect. ??
It just seems like a wierd wear pattern and I dont want to buy new tires and have the same thing happen, my money tree isnt blooming yet.

 

get new tiers have them put it on and make sure to get them allined to were you can let go of the steering wheel and it dont drift , if it drifts bringit back and have them re allined , i never had the probs but my work truck does

 

In the two years Ive had the car Ive had it alligned 3 times. Im about ready to rip out everything that deals with the steering and replace it

 

Outside tire wear is usuall either Camber adjustment or toe-in. since I am assuming the driver side is wearing ok I would say the camber on the right side is too far positive makisg that tires contact patch towards the outside of rather than where it should be

 

Tire wear on ONE spot around the circumference is the fault of the tire. It's called "tread separation".

It is NOT the fault of the car, or alignment, or anything else; purely an issue with the tire. You need new tires.

It can happen to any tire, from hitting a pothole or a puncture you don't notice or any number of other things; but cheeeep tires are FAR worse about it. The old adage about "you get what you pay for" applies to tires, with a vengeance.

Don't use the stock alignment specs. They create that outside-edge pattern of tire wear. Instead, have them put the left wheel at about -0.5° camber and +3° caster, and the right at about -1° camber and +3.5 caster; with about .05" of toe-in. If the caster won't go that far positive on both sides, have them put it as far positive as it WILL go, with a .5° split to the right like the specs I gave.

 

I agree with the alignment spec you suggest I guess that's a problem with not seeing the tire I am assuming it is wearing the outside edge all the way around the circumference. If a tire is separated it can feel like you are sitting in a rocking chair sideways at low speed less that 15MPH or so and rattle your teeth loose at higher speeds which will cause a bald spot in one area, if the alignment is the problem the wear will be relatively the same all the way around the circumference. I have seen a seperated tire cause a false engine mifire code in an OBDII Lumina at speeds above 75. I would venture to say these tires haven't been rotated as often as they should have.
