Hey guys I ordered up some new 20" wheels for the M6 and they come in in less then 10 days. Can some one help me with tire sizes?

New wheels are

20x9" Front
20x11.5" Rear

I know stock is 255/40/19 on a 19x9" rim and rear is 285/35/19

so I was thinking 255/35/20 Front and 305/30/20 Rear .... but there is no such size as 305/30/20 that I could find and I was hoping to stay with the PS2s :p

It depends on your springs as well...if you want to fill in a nice wheel gap along with a drop, the 255's and 285's have an appropriate sidewall amount to fill in the gap. So the 305's will have a lower section height, but more wheel gap.

Are you sure about the 11.5's for the rear? I was under the impression that any wheel over 10.5's could rub...? I heard this from a couple of wheel venders but not 100% sure. If it works out, a fat rear is always nice. A little junk in the trunk...Yah! :thumbsup:

11 with the most perfect of offsets will be ok, 11.5 sounds a bit big to me.
