When the car is on the ground, the size of the wheel tub can't be discerned anyway unless you offset the wheel/tire way too much inboard.

245/45-18 = 26.7" tall.

I'm doing a 255/40-18 on a 9" wide wheel @ 26" for the front of a g-body Malibu & that's considered 'tall' for a mid-size "pro-touring" ride. Most are less than 26" up front for sure.

A 315/30-18 = 25.4" for reference of a very common 18" pro-touring rear. Many are opting for staggered 18(F)/19(R) combos now w/a 325/30-19 @ 26.7" tall.

I'm all about a 4" tall sidewall (as close as possible if not 4") for best ride quality.
