Abnormal rear tire wear

djantlive · 12-11-2012, 01:13 PM

Both of my rear 19" tires have severe wear on the inside of the tire, not the middle of the tire but the side that is inside. tire is sumitomo hrz and replaced this year. but the tires are showing the cord already on the one side.

Suspension is stock and wheel is stock too. Sounds like an alignment issue but I wanted to check if anyone else get this.

Car tracks straight and does not pull on one side or another under WOT or freeway speeds.

Thanks

alignment or its just a guessing game.

silly question, but how many miles on it since you've replaced them; time doesn't much matter.

djantlive · 12-11-2012, 04:41 PM

i think it has about 5-7k miles only.

its most likely negative camber. my x5 corded the insides of the rears as well. have more negative camber on an x5 then on an m3 stock if you can believe that. could be a toe issue also in conjunction with the camber.

you are correct. both toe and camber were adjusted. thanks!

Have you checked the rear trailing arm bushings? it's the most commonly worn out rear suspension part that causes excess tire wear.

tech thinks it's just alignment. let's hope so...

E46s are hard on RTAB, I'd suggest you change them every 25,000 miles.

new tires are holding fine thus far. alignment is fine now too. i have driven the car almost 1500 miles and went to a track also.

RTAB is fine. thanks for chiming in but i think you guys are overly sensitive about it. a new bushing every 25k? c'mon.... do you change oil every 1k miles too?

ghassanm3 · 01-31-2013, 04:22 PM

Bushings.. get them replaced. I went through 3 sets of rears before I realized it was the bushings. Since replacement the rear tires have been great.

Rear bushings. My brother went thru rear tires in 3k miles lol

Hey guys im having the same problem but my tires are running smooth evenly and not just on inside or out :-( I had to fit new tires today (3rd set since December) and no one here in Dubai knows why. does the fact that im running normal tires on run on flat rims matter?

So tire wear is even just too fast? How many miles and what's your tire pressure?

Yeah very fast, dont know in miles but i only get 10 000km on a set. pressure is at 2.4, and i dont have a wing that could cause a lot of down force
