Hey Guys,

Looking at new wheels for my M6, ACS Type V's (9x20" & 10x20). Not sure which tire size to go with but I do want a wider tire which is not recommended by ACS. Will be fitting PS2's.

I put together a little analysis comparing factory 19's, ACS's recommended fitment, and my proposal. Notice how the rolling diameter of my proposed fitment on the 20's and the factory 19's are about the same whereas the ACS's are a bit different.

Which is the preferred fitment and why? Your opinion is appreciated.

Thanks
