Read through the lift and tire info sticky and it said that 33's if they rub the bumper that it could be spaced out, How would I go spacing that out? thinking of just getting stock size tires for a better ride and less noise. Maybe better mpg and power with stock size? But every thinks they would look goofy so idk what to do. Right now I've got bridgestone dueler apt 32x11.50R15LT's on it but they are starting to dry out in treads and walls and getting bubbles on the walls lol.

Wheel spacers. This has been answered on here before 33s are the largest a stocker can fit. I believe a 14 inch tire is as wide of a tire that the stock rim can fit. You can google wheel spacers.

My 32x11.5x15's rubbed on the RA, so I bought a new set of rims that had an offset. That moved the wheel just out beyond the fender but now I have complete turn of the steering wheel without the tire rubbing.

I personally wouldn't go much bigger than 32's unless I installed a 2-4" lift. And, with a stock 5.8 I'd probably do a 4.11/4.10 gear change which is a major expense just to go up 1".

The factory tire size options for your 1990 Bronco was as follows:


P235x75R15 or 31x10.50R15
Lol, better than the early 80s Broncos which were stock 215 75R15s, or optional 235 75R15s.

My Bronco looked awfully funny with 27" tires.

Really a 14 inch wide tire on a 7.5 inch wide wheel? I would not go to 12.5s on the stock wheel, but some say it is doable that way.
12.5 fits fine on my rims. When I wheel I air down below 10psi and never had a problem popping a bead

i have 32's mounted on alcoas and they rub on the sway bar and the radius arm at full lock.
my suspension is stock...well, i have upgraded shocks but it's stock height.
the biggest tire you can have on a stock bronco is 31" without any rubbing issues w/o modifications.

Like I said some do it. I would imagine that you can not run much more than 25pis on the street to keep the wear OK.
That's pretty close to what I run, between 25 and 30 psi...anything much more and she starts wondering around on the freeway.

Pay attention to which years people are referring to. The body style breaks are 78-79, 80-86, 87-91, & 92-96. So 87-91s should be similar to your 90. 92-96s as mentioned above have issues with the front bumper rubbing long before 87-91s do.

I ran 33 x 12.50 x 15s on my 90 for quite awhile. I think they worked out fine. It had 3 minor rubs at extreme positions.
-They rubbed the sway bar at full lock before it was removed. Don't turn so far or adjust the stops.
-They rubbed on the radius arms at full lock. Don't turn so far or adjust the stops.
-The left front barely rubbed the chrome trim over the wheel well at full stuff. If the chrome wasn't there it wouldn't have rubbed.

I currently have 35 x 12.50 x 15s on it. They're too big with no lift or cutting. After running the 33s I wanted more clearance. I bought them knowing that it's getting lifted soon. They're ok on flat ground. They rub at the rear of the front wheel well opening if compressed much, like if I hit a driveway a little quick with the wheels turned. I tested them a little & it looks like there are lots of wheeling conditions where they would rub too much. Time for that lift.

ummm.... yeah, really? way too wide on too narrow of a wheel. I like to run the wheel width specified by the tire manufacturer for optimal performance myself.

What does she wonder about? why she's on the freeway?
