Hey all,

I need to replace my stock RFTs (already!!!) and wanted to search the used option first. I'd really like to avoid getting RFTs again, but for the right price I'd stick with them. They'd be going on a E92 335xi so:

Rear: 255/35-18 - I'd also take a 255/40-18
Front: 225/40-18

Let me know what you all have!

Thanks!

I have 2 245/40ZR18 that came off the C6 Z06. It has 5/32 left which new is 7/32. Michelin Pilot Sport. Don't know if that will help??

As noted, I have a OEM set of Potenza's with roughly 50% of the original tread depth left (fronts a little more, rears a little less).

Nothing wrong with them at all... no patches, plugs or curbage. I simply replaced them with all-seasons and it's not worth switching back for summer to me.

I live in Golden.

Let me know.

I have 4 sitting in my garage off of the sport package. I don't know how many miles are on them as i changed my rims completely as soon as I could (maybe 5000 miles max) but, I'll take pics and post them up in a little bit.

How many more times do we have to go through this...

Read the xi forum. If you want your transfer case to last more than a few months you can't use the 255/40s. Different rolling diameter than the fronts (3.6% difference according to the wheel calculator in the wheel and tire forum of this site. Not good in an xi. Actually, quite BAD. Please search first before asking follow-ups. Dozens of posts about this out there...

Good luck.

Well thanks for the blast, nomile!

I obviously wasn't aware of the rolling diameter difference or transfer case issues if I were to use the other option in the rear. The only reason I even mentioned it was because a dealer said I would be fine with them.....clearly he was wrong and clearly I was wrong for not doing the proper research.

Anyway, I decided to just bite the bullet and buy a new set. I bought the Michelin Pilot Sport PS2 (non RFT!). I'm having them installed tomorrow morning. I can't wait to drive on them!!!

Nice, those are very good tires. Cool looking sidewall as well.

I might have been a bit stressed that day and that questions does come up a lot - sorry for the shootin'. It is interesting that your dealer recommended those sizes. It would be highly unfortunate if dealer-recommended tires damaged the car.

Have fun on the new tires!! Those are high on my list for the next round of rubber. Great reviews.
