| Stock Rear= 16" + (0.45)(245mm) = 24.6470588 18s= 18" + (0.35)(275) = 25.5490196 Yep..you're right...It would make you accelerate slower, but get better gas milage on the highway...but probably little...no biggy i would think though...If it is, then just go with a 30 tire instead for the rear. That will get you a little under actually... 18 = (0.30)(275) = 24.4705882 Atleast you don't have 19" 295s like me...that is a pain. I'm just gonna keep waiting for them to come out with the NA gear that you can put in the TT diff, cause I have 19/35/295...and that is just way off....like...27.0980392 :\
