Sorry about the lack of clarity in description guys, Was on my way yto work this morning so a bit of a rush. I meant the width, as in the lexus website lists the fronts as 225 and the rear as 255, where as i have 235 for front so i wasn't sure if having larger than the listed 225 would cause problems.
Spot on! When i full lock there is exactly a fingers worth of gap in the inner plastic guard and i wasn't sure if that would cause problems when braking and turning? In regards to understanding offsets i kind of do :) I know it has to do with the amount that the tyre sits inside or outside of the wheel bay and that its important...but that's about it, im more of a computer guy not a car guy..i just know i love the is250 :)
when i look at the site for the wheels it says the wheels i got come in +35 and +45 offsets, looking at what you guys have written in regards to the pictures sounds like he has used the right offset, its just i have read things like +45 and +50 on US sites so i wasnt sure if there were goign to be issues with my set.
I rang Lexus today and asked if having 235 all round was going to be an issue wih warranty and in general and he said allthough the 18's from lexus come as a staggered setup, having 235 all round shouldnt cause any problems. When i pick up my caps later this week ill post some full shot pics.
Thanks for all your help so far guys!!
