Im reading that 235/45/17 is the closest to stock height (tire) I need to know so my speedo stays pretty accurate I want wider tires and a wider looking stance therefor the 7.5

that will work just fine, ive had this set up for about a year and a half with out problems.

if you're on stock suspension you might have an issue rubbing on 235's

nope...

i said MIGHT. some do, some don't, it depends on the tire and rim combination. just check before you spend the money on it.

The other might is lock-to-lock turns. Otherwise it works, but a 235 is considered too wide for a 7.5" rim by most tire companies standards. It weakens the sidewall. Its tehcnically not safe, but people do run it.
