Ideal tire width on 15X10 w/ 4" backspacing?

[Iron_Weasel]

Going to be putting a 4" suspension lift on my 79 K10 and I'd like to know if there is an "ideal" width.
I plan on running 33's unless I get a killer deal on some 35's and can't decide between 10.50 or 12.50.

For instance, I'm considering BFG AT's which come in 33x10.50x15 and 33x12.50x15. Also in the running are Dunlop Radial Mud Rovers..but those only come in 12.50 width.

Any insight as to which would be better and why?

i have 33 12.50's BFG at's and they are good. the 10.50's would look too skinny.

Pick a tire and get a rim that works with your tires. Don't pick tires based on rims.

A 10.5" tire on a 10" rim is going to look funny IMO. All the G-ghetto mexicans do that around here. They run 12" or 14" rims on 12.5" tires to get the balloon look.

For a truck that sees offroad use that is not what you want.

I run 8" rims on 12.5" tires. I like the look but for me it is about the function. 8" rims will help your tires stay on the beads when you are offroad.

12.5 is the minimum width I would even think about running on a 10" wide rim. I think my 13.5" wide tires are a bit to narrow for my 15x10's.

What tires are you running? I am running a 13.5" wide Irok on 15x8's and kinda wish I had 15x10's...too much crowning IMO, but thats with Irok's.

I'm running 36x12.5x15 TSL bias plys. They are marked 12.5 on the sidewalls but they are actually 13.5" wide if you look at the specs on the web site. I've seen guys run them on 8" wide rims and don't know that I want that...Just need to find some 9" wide rims (or 8" wide with weld on beadlocks)

i had 35x12.50's on 10" wide rims it looked funny to me the side wall was flat no bow in it
i put the 15/35/15 tsl's on them look much better and the tsl's actually say 15x10 rim recommended

good rule of thumb is min. 2" bigger tire width vs rim width. so a 12.50 tire is the smallest you want to go on a 10" rim.

i had 35-12.50 bf mallterains on 15x10 looks funny.now have 38.5-15 boggers on 16.5x8.25 not too bad.

i ran 35 12.5 on a 8.5 wide rim for years never had any problem now i have a 15 on a 10" no problems yet and on the side of my tsl 15/35/15 it even says rim size 15x10

I'm running Pro Comp 31 x 12.50 x 15's on 8" rock crawlers on my stock '87 Blazer and I think the look and work fine.
