get 18x10 with 42 offset and roll the fenders front and rear
then put on 295 30 18 all around

thats about how wide you can do...with some moding of the car..and you might have to eliminate the fender liner in the front.

i have 285 30 18 advan A048 on mine. unfortunately i only have a 9.5 wide rim so thats why im stuck with 285.

30 profile is just too much for me. or should i say, not enuff. i live 10 mins outta philadelphia and i commute to work TO philadel[hia and i cant ride on 30s on those garbage things pennsylvania calls "roads". 40 is my personal limit but will budge to 35 if need be. is 255 40 on 18x8.5 reasonable? or is a 35 profile suggested?

 

You have the right size in mind. 255/40/18 on 18x8.5.

 

i thought so, falken doesnt make the 615s in 35 on 255's anyway. im set.

 

what wheel offsets would be best for this setup u mention???
255/40/18 w/ 18x8.5 front
255/40/18 w/ 18x10 rear

 

shameless bump^
