Im most likely gonna get 18x10 and(285/35/18) 17x9 rims(275/40/17)....since the sizes of the tires are a lil different...wat do i do to get the spedo corrected? im not planning to buy an xcal II at this point in time...do i just take it to a dealership and have them reflash my computer?

 

?????????????????????????????????????

 

Not sure about that one. Xcal will correct for gear changes but I don't know about tire size.

 

it says tire selection right in the add:


any one else
