I tried the search but came up with nothing. Is anyone running 33x12.50 x15 on stock 7" wheels? I know it is recommended to have 8" wheels but I am just curious. I would think the front would be very close to the upper arm on a ifs truck.If you are do you like this set up? Do they wear uneven ? Post any pics.

 

jacksonpt is running 33x12.50's on stock rims. look him up, he's got some pics on here

 

The only one other than Jackson that I can remember doing this was Leo. He had a sweet 2nd Gen with BFG Muds.

Actually, 10" wide are usually recommended for 12.5. I'm running 8" and have had no ill effects in the year I've had them on.

Some are trying 10.5 x 33's on the 7" wheels also.

 

That's what I run.

I heard with the 12.50's on 7" the bead isn't as strong when they are aired down?

 

I met a guy the other day who was running 35x12.5's on stock 2nd gen alloys (15x7's) he seemed to like the set up. I met him on a run and he had them aired down pretty low and had no problems.

 

met a guy running the stock 16" taco alloys w/ 33's he was running a 1" adapter he said he had no rubbing in the front just a bit in the rear when flexing

 

I am running 33x12.50 bfg muds on my stock wheels. They seem to be wearing fine. Ive had them aired down to about 12 psi and they were fine.

 

There is a similar post over on Pirate4x4.com. That one deals with 8 vs. 10, but the recommendation over there in that debate is to go with 8s. Apparently, they hold the bead better and keep the tire from popping off the rim at low pressure.
I'm not really sure, but a 7 would seem to putting more stress on the sidewalls while under normal inflation and driving. I bet if you look around you can find a set of plain jane black spokes for pretty cheap. They look good and you don't have to care about beating them up.

 

i wouldnt recommend 12.5 on a 10" rim....i had that set up on my old jeep for a while....i lost the bead on many occasions....12.5" on a 8" is alot tighter, better for offroad, thats what i eventually went too and never had a probably with the bead seperating again....12.5 on a 10" would be better for the street.....

 

ok everyone here is saying i know a guy who is happy with such and such.... let me respond..... a 35 is going to put less stress on the sidewalls and bead area as it actually has less leverage due to its incilnated angle.... you can physically fit a 33x12.5 on jsut about any rim... there is a first gen pickup that belongs to a custom of ours that has 33x12.50x15 general grabber mud terrains on his stock toyota 15x6" wheels... they fit.. look like too much tire for the rim and make it look all bubbly, but depending on what your air pressure is, hopefully the wear wont be affected.... thats another problem with the scenario... the narrower rim wont allow the section width of the tire to be properly utilized and that may contribute to less traction and worse/abnormal tire wear...

 

I run 33x10.50s on stock 15x6 rims and they work OK. Great off-road, on-road it is a bit hard to get even tire wear, the center tends to bulge out unless I keep the pressure in the low 20's:

Alot of desert racers run 12.5's on 7's but it's mainly due to the bead holding TIGHTER on a skinnier rim. Just the opposite of what GRNTACO says he's heard.

As you mentioned, it may be very close or even contact the outer most point of the upper contrlol arm in certain circumstances. This was the case on my stock alloys when I ran 32x11.5s BFG M/T's on my original Tacoma (95.5)

An 8" rim is what you really need for a 12.5 tire. For wheelin' use 10" is just a tad to wide for a 12.5. I run 9" wide rims currently with 12.5's and have never had a problem yet and I air down as low as 8 psi on the Rocks in Disney, OK. Back when I ran 8" rockcrawlers, I went as low as 6 psi without issues on the 12.5's and 8psi on the 10.5's.

I'd say if you go 12.5's on 7's and they clear the upper control arms, find a good air pressure that allows the contact patch to remain solid (do the chalk test) for good wear and you'll have great ability of airing down quite low with very minimal chance of loosing a bead. (I definately woudn't go below 6psi though!)

 

Don't want to hijack the thread but, I have 33 x 9.50 on 7 inch wide rims. No rear lift, t-bars cranked, no rubbing issues. Will 10.5's rub?

my truck is a 4x2, lifted with ford explorer 7" wide rims and i run 31x10.50x15s.... they dont rub.. but ihave also modified the fender and done the pinch weld mod as well....

 

Yep... 33/12.5-15s on stock 15x7 alloys. No problems, looks great, works great. This is one of the better pics I have from the side... so you can get a good look at the tires/wheels.
