Swapping Tires Question

My M3 ZCP came with PS2 RFT 245/35 & 265/35. There's an opportunity to swap them for a set of RE11 235/35 & 275/35 from a C63.

My question, is this a good idea? Would you do it? Also, would the 245/35 be okay on a 19x8.5?

Consider that the cost is only at the tire shop.

Thanks

If you got your M3 new, your car did not come with runflats (did you buy used?) I wouldn't switch to those front tires even if free, 235/35 is quite a bit shorter than stock and you will lose grip from arguably an already under-tired front. 245/35 is perfect for an 8.5" wheel, that is what comes from the factory if you get the stock 19s. ZCP wheels are 9" wide in the front and work best with a 255/35 front. If you can get just the rears from the C63, get those and pair with RE11s in 255/35 for the front, that would be a great setup on ZCP wheels. Check the load rating for the rears though.

I am currently running a 19x8.5 245/35/19 tire and it fits perfect. Offset is +35 on my Volk Magnesium Blue CE28 but today I move over to 18x9.5 +22 front with a 255/35. Probably will swap out to 265 though. That 19x8.5 with a 245/35 is a E46 M3 offset/size though.

I'm in Hong Kong, my car is Right Hand Drive and specs are different (no ugly yellow sidemarkers, folding mirrors come stock), and yes the ZCP comes with PS2 RFT (as denoted with a star on the tire).

Thanks for your recommendation.

The star means it is an OEM BMW tire, not a run flat.

Good to know, thanks

Then I'm having some mighty traction issues.

Was in a clear, flat, and dry road (rural); car is wheel spins on hard launch, then from 1st->2nd, as well as 2nd->3rd... And I thought the PS2 was supposed to be some sort of a good tire. It really takes an awful long time to warm up.
