Wheels and Tires

Currently on my 68' im running 235/75/15 but would like to have a larger tire. What is the largest tire I could put on this truck? Feel like the tires are small looking for the truck and would like something larger. Would 30x9.50R15 fit?

Yes.. 30s as spec'ed above will fit. My 70's spare wheels still wear em.

I run 31x10.50r15. They fit nicely and look good. I have seen a couple of trucks with 32x11.50r15. They fill out the fenders completely and give a big meaty look.

I am running 33 x 12.5 x 15 with no issues on my 68 4x4

Correction. The issue that I do have is that with such a wide tire, and no power steering, I believe that the bushings in the steering components prematurely wear out. That's why I have a lot of play in my steering wheel.

Btw, my response above assumes the OP has 2wd and stock wheels... 15x5.5.

Yeah if you want to run a bigger tire, your gonna need some wider wheels. I would recommend 8" wide.
