You have more pull than I do. R1R and ZII's are available in the 225/45/16(decent price on the ZII). I like the BFG Comp-2 for DD Summer duties, but I've yet to really see some decent tests out of it against, say, the Conti DW or something else in the category. BFG C2's are cheap and WIDE, too. Really wish I had a set of 16x6 wheels to try the 205/50/16 BFG C2 out on.

225/50/16 Rival is what I'll try to cram under this turdbox for autox next year if nothing else surfaces in the 225/45/16 size. I'll probably try to scrounge up the lightest 16x6(or 15x6) in a 4x114.3 bolt pattern I can and run RE960AS's for daily. Really liked those tires on my Integra, did pretty well the handful of times I autocrossed it.
