I'm in Connecticut and was 30 seconds away from putting down a deposit on a six-speed G35 Coupe last night, when I mentioned snow tires to the salesman. He then explained that nobody makes snowtires for the 18 inch wheels that are standard on the six-speed, but that Infiniti is "working on the problem." Does anybody know anything about this, or had any luck finding snow tires for these wheels?

 

Lots of posts on this at the FreshAlloy site. The best set up appears to be 17" Mille Miglia HT3 alloys with Pirelli Sno Sport 210s: 225/50/17 Front and 225/55/17 Rear. TireRack will fit you up with this combo in the USA. Ask for Luke. I just put this setup on my 6MT (with the original 18' wheels and Brembos) and it works fine (tho' I have yet to try them in the snow...its coming!) Good luck.
