33x12.5x15 What wheel size?? 8" or 10"

Heres the deal! I'm going to order black steel wheels for 33x12.5X15 and I want to get the correct size wheel and back spacing the first time. My jeep has a 3.5 bds 5/8 shackles and a 1" bl . I was going to get 15x8" wheels but the guy at the tire store really thinks I should use 15x10". Whats the correct size for this tire size? I like the crager wheels but do they give the correct back spacing for my needs?

Thanks!

spark plug,

The correct width rim would be 10" for 33" tires but most people don't go with those due to the wider footprint, most run 8". With 5" of total lift you should be fine with 33's on 10" rims and check with the store rep on the particular crager rim you want in regards to backspacing.

There are numerous reasons why a 8" wheel is better suited for a 12.50 wide tire. Try a search on it.

I ran 33x12.50x15 tires on 8 inch rims for years, I never had any problems when aired down and never blew a bead. I am now running 35x12.50x15 (same width) on 10 inch rims and have blown a bead twice. If you are going to wheel it stay with 8 inch if not go with 10 inch it will make the tire look wider.

Sometimes it depends on the make of tire.
Some manufacturers list 8" rims, while others recommend 10".
I believe the major factor is the tire contstruction itself.
Both of my YJ's and two of my other 4x4's running 33's all use 8" rims. I have never had a problem with that width.
Mind you, I have run mostly BFG MT's or AT's, and my current YJ runs Goodyear MTR's.

Check out National Tire at: http://www.natltire.com/
They have a great wheel and tire fitment chart, as well as some really good package deal pricing.
I have bought several tire and wheel packages from them and have never been disappointed yet.

Just my .02

I wouldn't get too concerned about the backspacing unless you're planning on wheels 10" or wider.

I believe that most 8" wheels will have similar, if not the same backspacing as the factory wheels.
Even many 10" wheels will, although that is the size that many manufacturers seem to offer different backspacings on.

Most of the time the extra width is put towards the outside if the wheel, creating the wider track. That's another reason why you will go through wheel bearings faster with wider wheels that have all the extra width just thrown towards the outside (instead of having the proper backspacing)

Just a thought from a lunatic mind.

Go for the 8" you'll get wider foot print on lower air.
