Mein Auto: 2011 BMW 328i Coupe
Conti RFT with 3 1/16 left, how much longer?

Hi-I bought a 2011 coupe with 15K, 5 months back. Now I have 18.5K on it but the Conti ProContact RFT still have 3 1/16 tread front and rear. Some members say that they wear out after 20 or 30 thousand miles but mine seem like they are almost new.

Since this was my first BMW I really didn't know the Coupe was a bit more hard riding and noisier than the Sedan. I love it but a bit quieter and softer would be nice. I can't wait to put some Conti Extreme Contact DWS non run flats. (per members' recommendations)

Anyone have any idea how many more miles I should get with 3 1/16 tread left??

This means 3/16" or 6/32"? If so when do you plan to replace them at 2/32" legal depth or 4/32" typical depth to avoid hydroplanning?
I replaced mine at 4/32" which was 38K miles. I would guess you have 10K miles to maybe 15K miles before hitting a depth that would make them wise to replace...

3/16

Sorry I edited the post to change 3 1/16 to 3/16 but for some reason it did not change.

I measured 3/16th front and rear

6/32 left and change them at 2/32 you should see an easy 20K miles. If you go to 4/32 you are looking at 10-15K miles before hitting that limit...

My Contis are just at 4/32 and it's starting to show when it rains. Going to swap them out soon.

Our owner's manual recommends tire replacement at 0.12 inch, or 3mm; a wise choice IMO...particularly if you live in a rainy area where hydroplaning could be an issue. The traditional 2/32nd" (down to the wear bars) is only a "legal limit," not necessarily a safe limit for rain soaked highways at speed.

+1

I've read several articles recently that testing is now showng that wet traction degrades rapidly when tires hit 4/32 tread left, even thoguh dry traction will usually stay reasonable until only 2/32 left.
