E46 Tire Wear - BMW Forum

clarkinc · 02-24-2005, 04:22 PM

Hey guys, has anyone witnessed excessive tire wear on both the rear tires? My 3er is equiped with factory sport suspension and the tires are incurring sharp wear on the inside at about a 45 degree angle. Ive had an alignment done three times... the first time by an after market tire shop the next two by the dealer. Still the same effect.

I have heard this could be the shocks but have also heard it could be something in the suspension bent. Can anyone help?

it could be something bent but i doubt it since both are wearing, and an alignment wouldnt help you since its in the rear, and you dont align the rear. yes shocks will have that affect, wore out springs will affect the camber more-so than the shocks, shocks dont usually affect the camber too much

^ What he said, but I would like to add that it could just be the tires. Being that our cars are rear wheel drive, there will be more force applied to them, hence, making them more susceptible to wear. On my 328i, I've got snow tires. The ones in the front still have PLENTY of tread left, however, the rears are bare right in the middle. I'm assuming by centrifical force as I do alot of highway driving. Just something to think about.

true, but you prolly had too much air in the rears to begin with, you do make sense though. A 45 degree angle is a little extreme to be just the tires

Yea I went through at least three sets (moving the front to the back). It has to be something besides the tires, I don't think the sport suspension could be doing it alone. Thanks for the input.

Thanks alot guys...Youve been a big help in searching for the problem.

Any of you guys think it could be the bearings and or hub causing this?

e30fanm3 · 03-03-2005, 05:07 PM

no, you would hear that

I have been fighting with my dealer about this problem...my '02 330ci with sport package is on its 3rd set of rear tires, all because of the right rear wearing to the threads on the inside of the tire...I PAID for an alignment after the first right rear wore out and replaced with two new rears...and after 15k on the new ones, same thing happened. I've read where it might be camber? And i have to buy a camber kit?? Is this true?

Doesn't the sport suspension have -0.5 degree camber. This would cause more wear. I just can't remember if it is on the inside or the outside?

e30fanm3 · 03-27-2005, 02:09 PM

it would be on the inside but i dont think the sport suspension has any more camber, and you wasted your money on the alignment cause that has nothing to do with the rear tires

The second time I went in the dealer said it was the alignment again and wanted me to pay for it AGAIN...which I did not. Anyone have any guesses what the problem is then?

E46 rear suspension is adjustable so you DO align the rear. Just thought I'd mention this.

adjustable camber or toe?

Where are you located? I believe if enough guys gang up one one dealer they would have to at least look for a solution. Maybe we're too scattered to make a real differance.
