Default 14X32 tire on 12" wheel?

I screwed up. I had my rear end set up for 15x12 wheel with 5 1/2" back spacing and a 29.5x13.5 tire. I need more tire. Can I put a 14x32 on this set up?
Thanks

MT recommends 12" wide minimum, and a 15" max wide rim for a 14x32, it would be fine. could go to 14" wide rim with a 7 1/2" BS if you have room,

Thanks Boosted
I think I have the room but I don't want to buy another set of wheels right now. They ain't cheap. Plus I screwed up a second time by not changing bolt pattern. I had 5 on 5 axles so when I ordered new wheels I ordered same bolt pattern. That's not a very popular pattern so they are hard to sell. Should have done 4 3/4" since I was going to have to get new axles anyhow. Didn't plan far enough ahead. Act in haste, repent at leisure.

We ran Firestone 14X32 tires on 12" rims on my dads car for years going 9.60's. We did run tubes on them since it was the mid 80's.

I run tubes in mine to keep them from wrinkling too bad. It also quickens the reaction time.

I ran a Hoosier 32x14" on a 12" rim, know others that do also.

That's a lot of tire on that small wheel. What kind of air pressure do you run?

7.125 to 7.25 psi according to my Rebco gauge. Goes down track straight and smooth. Anything more it squirms a bit at the top end. Goes through at about 138.

Wow, if I go any lower on my 4000# truck my rims will hit the asphalt. Mine hits real hard when I let go of the button.

it will be fine but it works better if you use the stiff sidewall tire.
