just go with 10" wide rims. trust me, its exactly what you want. 12" wide rims just look goofy unless you're running a 15.5" wide tire or more.

with 35s, i wouldn't go wider than a 10" rim

 

My buddy uses 15x12 rims





















ON 44" SWAMPERS not 35x12's

 

Yea Andy's right, 15x10 is what ya want unless your gonna run a 14 inch or wider tire....

 

Running 15x12 on a 35x21.5 tire would be a very bad idea .

Here is a shot of my friends truck with 15x12 Welds and 38x15.5 .

 

sorry for digging this thread up, but i saw a rig on 12" rims the other day and took some pics to show everyone why a 12" rim and a 12.5" tire doesn't really work:

notice how the wheel is actually wider than the tire?

notice how the bead is also just hanging out, waiting to get caught on something. this is a 35x12.5 BFG

heres my 10" wheel. notice how the bead is tucked in farther?

its also quite a bit more protected.

i see a lot of people out here who run 12" wheel because they are "cool", but what you must realize that air is the only thing holding your tires bead out that far. on narrower rims, where the tire sits on the wheel is more like the natural state of the tire when its unmounted/has no air pressure. also, don't forget that if you wheel it, the bead will be that much more exposed to danger...

 

:stupid Good post Andy. You even have a scuff on your sidewall which if that happened on the 15X12 with 12.5" wide tire it could be enough to break the bead and instant flat!

 

yeah, i agree, a 15x10 is perfect, even if you want to run 14.5's i have 35x12.5's on 15x10 eagle 589's

 

i have 15x12 on my bronco with 35x12.50's havent had any prodlems with them, look on my superford page, theres a coulple up to date pics with the rims on the truck

and when was the last time you aired down below 10psi?

 

12 is crazy for only a 12.5 tire. if you are only going to be running a 12.5 wide tire, you only really want a 8" wide rim, 10" rim does alright, but once you air it down, you will be leaking and blowing beeds more often than if you had a 8.

 

you think 12 inch wide wheels are too much, i have a buddy that had 15x13 wheels with 35x12.50 bf all-terrains. looked like shit. but atleast now he has 35x13.50 maxxis muddzillas

 

and when was the last time you aired down below 10psi?

never had to air down below 10psi, and dont plan on having to do so, not many sandy places around here :toothless

with all due respect, you must be outside yo freakin mind! I run 33x12.30s on 15x8s and the truck will damn near change lanes without touchin the wheel. I run them at the suggested pressure and sidewall movement is scary when the wind starts blowing, or when you go to change lanes, basically anywhere you are required to turn the steering wheel :wacko

As a general rule i would keep your rims not more than 2" narrower than your tires. I have a set of 15x12's that I'm mounting my 33" dunlops on (13.25 actual section width) hich should handle decent on the street and still be able to air down (which is why I bought 12.50's, so I wouldn't have to air down) Maybe you guys with the BFG's have a section width that is smaller than advertised, like 11.50 or 12.00... my dunlops are almost an inch wider than advertised :shrug

(ps, I used to sell tires for a living, don't preach to me about how to measure the section width of a tire)

 

i had absolutely no problem whatsoever running 33*12.5 or 35*12.5 on 15*8 rims. the only reason i switched to 10" wide rims was to get the tires a little further away from the radius arm to help with my turning radius.

oh, and i dont recall SizeMatters ever saying that he was going to be using them on 12.5" wide tires....

dont shoot the messanger. lol. im not shure what to think. i herd this outcome from the mailing list from a local 4wheeling club. what was said is the 10" rim with the 12.5 tire doesnt air down to 10psi well, it will leak on you and is more likly to loose the bead. just what ive herd.

in the sand, my 35s are frequently below 10psi

 

Not to mention; anybody ever try mounting a 12.5" tire on a 12" rim? Way more of a pain in the ass than it's worth if you ask me.
