i'm a newbie here and just wanted to ask a few questions. i'm interested in getting the 5zigen gravis 1 in chrome 19 x 8.5 +45 offset. will it fit my 2007 g35. if so, what would be the best tire size to use. my other choice is the 5zigen sport engine in hyperblack 18 x 7.5 with 245-45-18 tires. please advice. thank you very much.

 

18s look too small. If you dont plan on lowering your car, a +45 offset will still be conservative but look ok. I'de recommend a staggered fitment where the rear wheels are thicker than the front ones. (i.e. 19x8.5 front & 19x10 rear) and then go with a +30 offset and +40 offset respectively. Tire sizes I would run either 225/40/19 or 245/35/19 front and 275/35/19 rear. Hope this helps.
