Is front and rear alignment always recommended when going to wider wheels/tires?


Never thought a vehicle needed an alignment based on wider tires, however yesterday I followed my wife in another vehicle as she drove the Sol home and admiring the recently installed and used staggered set of 18" Gravanna wheels (275s rears, 245 front) and noticed that the rear tires from certain angles appeared to look more splayed than usual.

I understand IRS tires never look/are sitting perfectly vertical in the wheel well but for whatever the rear wider rear tires was enhancing the splayed look.

Meaning / \
Instead of I I

Has me concerned the inside of tires are wearing faster than the outside?

Hmm. I would've thought that you might well want to change your alignment when you get new wheels - depending on the offset change (if any) since that would change your scrub radius.

Having it rechecked and just reset to factory specs wouldn't help though, of course.
