My fronts are 7" wide with 3.5" of backspacing and the tires are 24" and some change, I figured I can go an inch taller and adjust the torsion bars if needed.
The rears are already custom made, based on what they are charging for custom wheels now, it is definitely not in the budget.
I was trying to get more of a street tire out back, which was the reason for this thinking. But based on my current budget, there aren't really any viable options. Maybe next set of tires I'll look at it again.
