3 sets of tires in 1yr... Some help please

Alright i have a 04 m3 with 35k miles on it. I have had the car for almost one year and have burned through 3 sets of rear tires. The tires wore down on the inside part of the tire. I have done 3 full alignments and changed out the rear control arm bars. The stock 19 are on it and these last set of rear tires lasted about 3 weeks so it seems to be getting worse.

So wtf should I do now? I'm spending all my beer money on tires! Gonna take it back to my alignment guy tomorrow.

Ummm... How exactly are you driving it?

If you put soft sticky tires on it and squeal them around every corner, then they will wear out much faster.

Drive it like an old man. Just cruise. Got normal michelin tires.

Does the alignment reading keep changing each time you get it done? If it does, your bushing are wearing

and what have you checked so far? did you get an alignment each time you replaced your tires?
check for bent wheels too

35k is still really low... but... it could be bad fcabs and rtabs. also try to get a tire with a 500+ tread rating. the tires will feel a bit stiffer, but they will last a lot longer.

I'm gonna say RTABs. Upgrade to the powerflex ones.

Yes I got the alignment after each new set of tires.

I'm haven't checked of the specs changed at all after each alignment I'll look into that.

Powerflex (RTAB) rear trail arm bushing...

Search.

3 sets in 1 year. Come on man if someone slaps you in the face dont you want to know who did it?

before you buy new tires or go to an alignment guy search rtabs. they are your problem. ask around for quote on having them installed. Buy them and have them install. then buy your tires and get an alignment.

My guess is something is worn out causing your rearend not to be in alignment when driving. Usually its the RTAB's, but 35k is kind of low for them to go. You need to visually inspect all the rear bushing for cracks.

I had the same problem.
I replaced the RTAB's. No more problem.

Thanks everyone gonna try to swap the rtab's this week.

RTABS are done for, powerflex is the way to go, get the polyurethane ones, i had your same problem, i got those and did an alignment and so far so good

I ordered the rtabs lst night. hopefully it fixes the problem. this is a pic of the tire that i bought about 5 weeks ago

So for all of yall out there, is there any other way of knowing if your rtab need replacing beside just early tire wear? I mean can this be determined visually by taking the tires off somehow?

Does your car move to one side when you stomp on the gas? Or dive to one side when braking?
And when changing lanes, does it feel like the back end is going to come out?

Yes. Take it to a good shop that knows BMW or German engineering in first place. If u upgrade to coilovers or especially diff springs just change immediately. By all means do not go through 3 sets of ps2s in a short amount of time like that. IMO this is one of the first things that should b done to these cars. Just do it right away when u buy it.
