Re: Wheel Tire Fitment Advice

Yes, those wheels will fit, front and back without issue. ....with some of the 9.5" wide wheels, and with stock brakes, some guys have an ever so slight amount of rubbing up front, and it's common to use a .25" spacer. -But with only 9" and not 9.5" I don't see you having any issue at all.

FYI, I have to assume they're the right bolt pattern, right!?

Well, that’s my post from January, 2021…I put 275/40/17 tires on all 4 corners, and have been extremely happy with the look, durability, and handling.

Re: Wheel Tire Fitment Advice

Did you install the front spacers too?
are you running oem springs or lowered?

Re: Wheel Tire Fitment Advice

The spacers are really needed, otherwise, the tie rods can hit the inside of the wheel when turning tightly. I replaced my front springs several years ago with new OEM springs, so I’m running at close to the factory ride height.
