hey all, ive owned my 2002 e46 m3 for 1year and a half now. I havent had any big issues with the car besides my tires. the inside of my tires wear out wayyyyyyy to fast(3-5k and inside of tire is shot), but the rest of the tire is fine. Ive been through 5-6 sets of rear tires in a year and a half now. the fronts are fine(still with the original 2). ive done everything to try to solve the inside wear issue and nothing seems to help, that im considering trading in my car for something else. ive done so many alignments on the car(prob around 8 alignments), bmw says nothing is wrong with it, that all m3's come with a slight negative camber, which i understand for a performance car, but wearing out inside tires in just under 3k miles, is not normal. ive been through all different size tires as well, i had 255s/225s stock rims on it for about a year. this past summer i picked up a new set of csl 19' wheels, 275s rear/ 245s front. and guess what? same issue, inside of the rear tires are shot just after 3k miles. ive used michelin ps2's(worst tire wear, they were completely wore out in 3.3k miles), continentals(tried all weather tires, loose some performance for thread wear, but that dint matter much, inside of tire wore out the same as usual), Brisgestone's s03( wore out in about 5k miles), and some other cheap brands i cant even remember. anyone experience this problem with their m3? and what did you do to solve it???

I do not burn out or do donuts btw. i drive hard once in a while, but besides that i do regular daily driving.

I would check your alignment specs again. sounds like too much negative camber. Have some one other than the last person you had it aligned with to align it with a street setup. I had two M3's and the tires never wore like you described and I had over 5K miles on a set before I sold it and it was even across all the tires.

2 questions:

1) is the car lowered at all (that greatly increases negative camber)
2) Has the car ever been towed? If so, the tow guy could have damaged the rear camber arms (tow drivers love to put the hooks on them) and when they bend or stretch, rear camber is all out of whack.

Have you replaced the RTAB bushings?

1) the bmw did tell me the car was lowered and had after market springs. not sure which springs, i bought the car like this, and they quoted me $800 to replace the after market springs to the stock ones. they also said i had offset wheels(275s rear/245s front)which is why my tires are wearing, but thats definately not the case, cause i was running stock tires 255s, for a year.

2) never been towed while ive owned it. maybe in the past.

Do you beat the hell out of your car? If not i wouldn't say that is normal for your tires to wear out that fast.

Actually, based on the BMW Service Manual, the wear you are talking about is normal. Check the alignment if you want, it could possibly help reduce the wearing if you tweak a bit.

12,000 on my PS2's and still might be able to coax another 3000 out of them. Even wear, if anything a little more worn on the outside shoulders. I'd take it to the best tire/wheel/alignment shop in your area - they'll sort it out for you.

:wowee:1) Find another dealer. 2) find another alignment shop/specialist.
the surest way to not change the results is to not change those who are working on it.
I got 26k on the original Contis, 24k on the Potenza-S03s and now 13k on my Potenza RE 050A Pole Positions after H&R sport/lowering and they look like they'll go 20k more.

Sounds like a set of adjustable rear control arms, and GOOD alignment shop might be your best bet. I know there isnt a lot of room to adjust camber in the rear with the stock set up, which makes lowering springs push negative camber out even more than stock with no way to correct it. But adjustable arms will provide you with the extra room to straighten everything out so your sitting evenly on your rear tires.

they quoted you $800 for STOCK SPRINGS ZOMG!!! Unbeleiveable, but so not surprising..

you say you've aligned it 8 times so I don't know what to say to help you, but I will say I go through tires rather quick too... if it makes you feel better

I know everyone likes to believe negative camber... true, but toe is the main prob with excessive inner tire wear... Hence the RTAB someone mentioned. If possible, may you post up your past alignment specs? Have you ever replaced the RTABs? I would also suggest like others have stated... go to another place if you haven't already.
I live in NYC and I run a staggered setup as well as do most, and I am lowered on TCK c/o no tire wear like how you describe.

Well, either you drive like an idiot 99% of the time or you have some major alignment issues. My 330Ci man wore the outsides of the rear tires first at about 30k... Michelin Pilots.... My M3 has 34800 on the Contis and wore the same... Yes, 34800 miles on the original tires from new. They are getting replaced this weekend. I have tracked it and I do drive it hard on occassion. Probably about 20% of the time. It has had it's share of drifts and flat out stupid acceleration around corners. The cornering loads are no doubt what contribute to my outside wear.... Your inside wear with the negative camber leads me to believe that your toe in is way too positive(tires pointing out from straight line) should be a few degrees in on the rears) or you habitually drop the clutch and smoke your tires or just pound it on a daily basis in straight line acceleration....There has got to be something causing it...
