Is anyone running 33/12.5/15 tires on a 15x7 rim? Just got some new tires and want to use the AR rims that I already have.Is it safe to run a 12.5 wide tire on a 7 inch rim for every day driving? Thx MM

You'll end up with the middle of the tread bulged out badly, so it will handle weird and wear badly, so I would say no, it's not a good setup.

Welcome to the board. There are a lot of good people here. Also and endless supply of information. Would you please fill out your profile. I'll just about guarentee there's another member in your neck of the woods. There are students here trying new stuff and old geesers(sp) that know every nut and bolt. Years ago I had 11-15's on 8" wheels and had to keep them down to 20 psi on the street to have even wear, then I would bounce over any uneven intersection. PIA! Stick around, by helping other people here they will get to know you and maybe somebody will swap or sell you some wider rims.

I run 33x12.50 bias Swampers on what I believe are 15x7 rims. Prior to that was 2 sets of 31x10.50s, 1 set of 32x11.50s (all 3 sets on my brothers CJ), 1 set of 33x12.50 radials, and the current rubber (on Mossy). Other than shredding one of the radials, there haven't been any problems. I keep them @ 25-28PSI on the road and about 10-13PSI offroad.

I running 33X12.5 on 7 inch rims.
but they were used tires. $25 each. even though I've had no "tire" problems over the last 2 years/10K miles ( can you tell I drive my jeep allot), I would not put $600-$800 worth of new tires on 7 inch rims.

I also discovered 2 weeks ago that my rims are bent. cheap AR outlaw2s, they have not been able to handle the mild abuse I dish out. and I though the week link would be the Dana 35.it is funny cause my tires got nosier after my last off road trip

Ok, Thanks all. I think that I might just buy some 8 inchers.

Might as well go for the 10"

If you're goning to air them down off-road you'll be better off with 8" than 10" rims.

 

[2344]

wouldnt airing down make the tires want to roll over more if you were running the 8" ?

 

[Frosty]

Tires will stay on the narrower rim better aired down. It's not rolling over that's a problem, it's separating from the rim.
