I have a set of almost new 33X10.50X15 BFG KM's and wondered if I can put them on a 15X10 wheel with a 3.75 BS? I can get a good deal on a set is why I'm asking. I plan on 33X12.50 on the next set.

Will work as long as you dont air down too much while wheeling. If you plan on getting 12.5" you wont have to swich wheels. BTW kinda odd size..33-10.5?

I'd recommend an 8" wheel. A lot better off road because you can air down a lot farther. The rim is just too wide for that tire width anyway, especially with the taller tire. It'll have more sidewall flex which can make it easier to break the bead.

A 10" wide tire is better suited on a 7-8" wide wheel. I certainly wouldn't wheel a 10" tire on a 10" wheel as your sidewalks would be way too exposed and not to mention popping a bead would be a huge problem when aired down.

A 33x12.50 is doable on a 10" wide wheel though if wheeling I would suggest a 8" wide wheel to protect your sidewalls and beads.

Do you happen to have any photos of these 33 x 10.5's on your jeep?

This is the size I have been thinking about, I currently have 32x11.50's. I want a taller tire but do not want anything wider than what I currently have

I recommend a 7" wheel with the 10.50 wide tire.

I routinely air down to ~12 psi for offroad without any problems, as I still have a 3.5" difference between the wheel width and tread width.

With an 8" wheel, you only have a 2.5" difference. This can cause you to lose the bead seat or pack the bead with mud/gravel, making airing back up impossible without cleaning the bead. (BTDT ;) )

Here's a couple pics of 33x10.50 MTs on 15x7 wheels with 3.75 backspace and Rubi flares (stock flares in the first pic).

Thanks for sharing photos, I really like that size of tire. I have stock wheels, not sure of width, will have to do some looking
