Im up to 27,200 on my rear 20's..i think i have another 3k left in them
 

how many miles did you get out of your rear dunlop 20"s?

22K all around. My rears looked like a ocean wave on the inside. Switched to the Bridgestone after them, got 38K out of them.

Do either of you rotate your tires?

didnt rotate since i had the other rear replaced due to nail
 

in tire plus i dont think your supoose to rotate on X

We're at 25,000 with probably about another 1k or 2k left. The Conti ExtrContact DWSs are sitting in the garage, waiting.

I just put those on! you're going to be amazed how much better the X is on those.:thumbup:

UPDATE AT 28,800..TOOK THE X TO THE DEALER AND ASKED TO CHECK TIRE..THEY TOLD ME IT HAD 4/32 ...NOT BAD I THOUGHT.. MAYBE THE TIRE WILL MAKE IT UNTIL 32-35K??? WHAT ABOUT U?

I have done 41,000 on the original Michellan run flats. BMW Service reckon I have at least another 20k left in them.

Mozzy you have 18" rims, the tires will last a lot longer. The OP was asking about 20"ers... they will wear much quicker.

None the less, good wear on those RFT's at any size.

I had about 23K on mine and the fronts were done but the back looked ok so I bought two used ones for the front for under $100.00 with 4/32 left on them. When they are done, the backs should be done too and I'll replace all four. I couldn't see replacing all four when the backs still had plenty of tread left. Those Dunlops are well over $400.00 each. I'll most likely go with the Michelin's when the time comes.

12k and was down to cords on the inside..high heat, coral content and aggressive driving killed them fast. I've got about 6K on replacements and they already howl, hoping they make it through the remainder of the lease (11 months).

My buddy with 22" Conti Ex DSW's is at 8k and looking to replace cause they are now noisy and almost smooth on the inside.

We're both jealous of all these miles you guys seem to be able to get..just not fair!
