I have a 1995 Cobra convertible. I am thinking of getting Nitto NT555 tires all around. Car is mainly daily driver but will do occasional hpde and light track fun. I am going to use stock cobra wheels, 17x8 all around. I want to preferably run same size tires all around. Stock size tires are, 245/45 17. I would if it makes sense to have tire fit correctly on these wheels that hangs out a little more over lip of rim than the stock 245/45 17 tires. Height of tires is decent but would like them to be slightly wider. What size do you guys suggest? Also, I notice that on this car the back wheels appear to be pushed in further than the fronts, maybe wheel spacers? If so, what size would make it look better? Anbody else make these besides maximum motorsports?
Thanks, Gerald.
