What size tires should I run?
 

I will plan to pick up some 17x7.5's in the front (+45mm) and 17x8's in the rear (+48mm) sometime in the near future. What size tires should I run? 245/45/17's in the rear? Front? I'm new to buying tires for a car with a staggered set up. thanks.

215/45/17 front, 245/40 rear

and if you plan to lower your car, get more negative camber alignment in the rear like UK alignment

my car is already lowered a little bit on some teins. i do plan on getting coilovers but not quite yet. wheels and tires will come first. it was just aligned after the springs were put on back a few months ago, i shoulndt have to get it aligned again after throwing new wheels/tires on will i?

It depends how much your car is lowered. It might rub. You don't have to get the alignment again if it doesn't rub.

ok cool. they are just tein s-tech's so very minimal drop for the time being
