So I bought the xxr 526 18x9 front and 18x10.5 rear. ..I used the tire size calculator and decided to put 235/45-18 on front and 275/40-18 rear...that's only a 1.3% difference in size...so why the hell is it throwing a vdc lights on if it allows for 3%....now if I run a 245/45-18 in the front it is the same size as the 274/40 but I just didn't what that much meat up front...can someone shed some light on this for me..I'm new to the g35 stuff..owned a 500+hp Evo for the past 3 years so this is all new..any help is greatly appreciated. .thanks*
