Rear end sliding... HELP

This issue has been happening for a while now and I'm starting to actually get a little concerned as a safety issue. Tonight in the rain driving home I kept getting a sliding feeling in the rear and it causes me to fish tail or slide a little and then the steering wheel will follow and I have to fight it a little to keep me under control. But tonight going no faster 40 around a slight on the boulevard it went ape Sh** and went sideways completely. At first I thought it was the subframe bushings and replaced them with powerflex and it didn't solve the problem last week cause it happened last week also. . So I got home tonight and looked under the car and everything from what I could see is sound. It happens when I'm just driving straight too or when it's dry out I feel the rear end float or move a little when going over a bridge and going ober the expansion joints or hitting a dip. Has anyone experienced this problem? I'm putting the car on the jack this weekend and really checking everything out. Want to get everything checked out before the snow comes and I end up in a ditch. I know xi's are a little floaty but I don't think its supposed to be this severe. Sorry for such a long thread. Just need some help

I had the same problem with my E92 328i before too, my rear would slide and I would fish tail around corners. This was with my old tire setup, it was going bald so I changed my tires and it fixed the problem. I still get it now and then when roads are wet but it's because i'm running stretched tires on my new setup so it's expected.

When was the last time you got an alignment and maybe your car was hydroplaning?

I honeslty didn't even think of an alignment. I'm putting my winter tires on this week so I'll have it aligned next week and cross my fingers

Check tires and alignment. Ccheck codes being thrown by the TCU. Also try holding down DTC to turn off traction control for testing, carefully.

I think it was the tires. Threw on my winter set up and it's fine. I have a feeling the side walls on the tires were just super weak and had no real support. Scrapped those tires and getting some faulkens for the summer set up

Its your tires set up for sure. If the diameters of the front and back tires aren't the same even going in a straight line is going to be hard because the front or back tires will be rotating more then other causing a spin out.

Hope this helps!

What size do you think I should go with? I was running 275 (19x10) in the rear with a 235 (19x9) upfront. Should I go with a 265 on the new set?

I would stick with those sizes. (Assuming they're 275/30/19 and 235/35/19) That will give you the closest rolling diameter front to back.

When I had 19' I went with 235/35ZR19 and 265/30ZR19 it was perfect because the Overall Diameter was only off by .1 that is the biggest thing you have to look at when buying tires. You can check tire rack. com for more information on every tire before buying it somewhere else that's what I do. I have 20' on now.

only my e46 m3 did that and it ended up being loose trailing arm bushings.

Wow our (AWD) cars are really sensitive to the tires not wearing out evenly. This is one of the few times I miss FWD and rotating tires.

Nobody says you can't run a square setup, so that you could actually rotate the tires!

No, your setup is perfect! Rolling diameter is well within tolerances. You probably just had worn out tires.

Thanks guys for the replies. I'm almost positive it was the tires cause I have my winters on and no issues

+1 on tires

On this car and my old STI, nearly bald tires would cause the car to fish tail. One time I went sideways. Not fun and yet fun at the same time. I did recover without incident
