Currently looking at a set of Halibrand-style 17" wheels from Vintage Wheels. I'll need custom backspacing on the front wheels or 1.5" spacers - obviously the former is preferable.
Tire sizes will be 245/45R17 front and 275/40R17 rear. Right now the leading contender is the Firestone Firehawk Indy 500 tire. UTQG is 340AA.
Tire Rack rates it very highly for dry conditions, not so much for wet conditions - but I'm not going to drive it in the wet unless I get caught in a freak rainstorm.
