Getting Motegi Touge 18x9 front 18x10 rear. I want to use the tires I have now, which are 225/45/18 front and 245/45/18 rear. Will this stretch the tires too much? The tire shop told me it would be fine, so did a rx7 mechanic. I plan on eventually putting the 245s up front and buying 2 new 265s for rear. Has anyone had any experience with slightly stretching tires temporarily? Thanks in advance.

 

Are these any good???
