How big of a tire....

How big of a tire can be run on a 72 4x4. I am looking at a set of 31x10.5 Mickey T's. I would like to go taller and/or wider. When will I start to run into problems? I have 8" ralleys on the truck.

Thanks!

Re: How big of a tire....

I have 33x12.50x16.5 on a '71 k20 and they rub the fender wells on a stock suspension. So I would think the 31" would fit without to much trouble. Not sure if the K10's have the same clearance as the K20's though.

31's will run with plenty of room.

I have the same, on a '72 K20. Many years ago, I notched the lower front fenders and clearance was good, though I also had add-a-leafs. I have since replaced the front springs with 2 1/2" Softrides.

No problem with 31" tires on stock suspension.

Re: How big of a tire....

One of the best riding stock trucks I ever drove was a 69 burb with 31x10.50x15 ATs. It was for sale in very decent on-frame resto for $4K. Man did I miss out on one there. (about 14 yrs ago)
