Would also like to know what rim size you are using and its backspace if possible. I was looking through tirerack and they claim a 10.50 tire will not fit on a 10" rim, is that true? Anyone care to explain? Would like to see this tire without a lift on the truck.

I've had plenty of 33/12.50-15s mounted on stock 8" ralleys no problem. Also have had 32/11.50-15s mounted on stock 7" wheels. Sorry, no pic right now but I don't know what they're talking about!

edit: Forgot to mention, I mounted 33/12.50-15s on stock 8" ralleys at stock height on my old '72 Blazer. Definitely filled up the wheels wells. They fit but rubbed a little making sharp turns. Only had them on a short while before I installed a 4" lift.

Here's a pic of my '71 4x4 with stock spring height and 6 lug rallye wheels running 31x10.50x15's on it. Need to take another pic as since this one was taken I installed new springs on the rear but maybe it will give you an idea. New springs are on the front at time of pic.

Better side view, new springs on front but not on rear yet in this pic.

33"x12.5" mounted on stock 8" ralley's(6 lug).
Stock suspension,no body lift on my 71 Blazer.
They fit fine with NO noted rubbing even at full stuff.

i got the same setup as bobby, 33,12.5 15` on an 8inch rim, no prolbems, and no rubbing.

I would not run a 10.5" tire on a 10" wide wheel, bead with let go EASY.

And if you run a 15x10 with no lift your going to rub, you need a 15x8 with about 3.75-4" BSing and you can clear them.

I'm running 33x12.5" tires on 15x8 with 3.75" BSing with 1-ton 3 leafers in the front.

A 10.5 tire will fit on a 10 inch rim but it is not a good idea--it tends to make the tire wear faster in the middle.

Not to mention this kinda crap happens even running 25 psi

I agree, but Destructo, we're talking about the thread starter's '70 K10 that has much more big-tire-friendly fender openings than 73-87s. Apples & oranges.

Here is a pic of my truck it is stock height with 33x12.50's on 15x10 rims no rubbing at all
