2005 GT - wearing out tires on rear too soon

My daughter drives this car and while she drives aggressively, there is no reason they should be wearing out on the inside like this. I have had it looked at by many techs. The last one simply said the axle is not right. There has never been any damage to the car in the rear. I think it may have been assembled badly?

And What tires are you putting on there? the cheapest tires dont always have the best tread wear.

On a side note, my 05 gt's stock pirellies looked like that before I got my new tires. I presumed that they were rotated from the front to the back get some more life out of the tires. Is somone rotating your tires? And if they are not rotating your tires rotating them properly can help with tire wear problems. Rotate the rear tires to the front before they get that worn and run them on the front. Then you can use the good tread on the fronts for the rear.

If you rotate freaquently enough some odd ball wear problems can be evened out buy rotating tires so the wear can scrub even or close to it, while getting better life out of your tires.

hmm...

check up on all tire brands you used. you can usually view customer reviews for most tires on tirerack.com. some people report very short lifespan of certain tires.

if you used only one brand every time you replaced the tires, those tires may have a serious defect, or are just poorly made.


BUT if you replaced them using the OEM Pirelli PZero Nero M+S all season tires, its almost definitely not the tires' fault... they lasted me FOREVER.
or, if you have the 18" wheels and replaced using the OEM BF Goodrich G-Force KDWS, those generally have at least average lifespan as well.

if the tires you used seem ok after research, look into having the rear axle serviced or replaced, perhaps even the differential (especially if it is a limited slip differential).

I was going to say check the balljoints but then I remembered its the rear of the car you have problems with... perhaps get more opinions on the alignment situation.

good luck!


P.S. I just realized, maybe your daughter is doing burnouts in secret! lol, probably not though, just a thought :yelpleased:

Tires aren't your problem.

You sure you know how you're daughter is driving it (i.e. Not doing burnounts, or allowing a boyfriend to do so?).

Not likely a manufacturing problem...or an issue with your rear end.

My $.02.

I usually don't get time to rotate before the wear is so uneven it is not safe to put them on the front. You can't align the rear axle - it is straight through.

true, but what I meant by alignment was checking the thrust alignment angle.

usually this is kind of a b.s. procedure, but I prefer to be thorough in my answers.

is the car actually your daughter's primary car or do you just let her drive it sometimes?

Only 2 things can cause that wear. 1: As many have stated (Burnouts , Doughnuts, Skidding with the Emer.Brake, or if they are really good Drifting). 2: Check the angle of the rear end. From the front lip of the rear fender opening measure to the rear of the rim. Do this on both sides. Measurements should match, if they don't check for bad bushings or bad lower control arms.
I have had 3 sets on the back of mine. All BFG's and I get atleast 20K out of all of them. And I do drive spirited and have been known to smoke them up now and then.

I have 23K miles on '06 and my rear tires still look brand new...I measured them 9/32nd tread depth when new...and now they're about 7/32nd tread depth (according to VA State Inspection they should be replaced when you hit 2/32nd tread depth)...so there's plenty of life left to them...sounds like someone is hot-rodding to me. :yup:
