Whats the best tire size to run on the stock v rims.

Im thinking of jumping to a 255, so it will be even with the rim edge and alittle more contact patch.

Can i up to 255 without issues of rubbing up front?

I dont think im going to go staggerd , just same size all around.

Im tryin to decide between nitto 555 or the bfg gforce t/a


Ive had nitto 555 before and loved the grip, but my buddie has these gforce and he says they are the best thing since sliced bread.. plus the gforce are a bit more money

I just went to 255/45/18 Nitto Invos on my V, and the sidewall is a bit larger than I expected. They were only supposed to be like 1/8" thicker sidewall and ended up being more like 5/16", so over 1/2" taller overall. They ride great, but the feel a little soft in the corners, although I have run it to 1.00 g's without trying very hard. I wish I had gone with the 255/40. I would recommend the tires to anyone.

I run the Team Dynamics wheels, and I'm very close to the spindles, but good enough to clear.
