so like the title says. i am bout to buy some m45 rims this coming week. and i looked up the tire sizes that come on the m45 sport and they are 245/40's. Do you guys think i should just stick to those? or do u recommend any other sizes? thanks.

Those M tires are the closest (almost identical) in diameter to the stock G35 tire. Keep it for now. If you don't like it, you can change to 255/40 which is the next closest, but your tires will bulge out just a bit more, and your speedo will be off by ~1.5%.

^when you say buldge out, do you mean like kinda look puffy on the side walls?
ok i guess i'll just keep them the same. i dont care much about the speedo, just what looks best, thats all...ya kno?

also do you have pics of your ride, or a link to pics of ur ride/
