Moving from a 31x10.50 to a 35x12.50 here in the next month...and wanted to know if my soft 8's would do. All the other posts i've seen don't so much as bat an eye at talk of 12.50 on 8" wheels?! so....am i a go??

 

your good, when you hit the trail air down to 10-12 pounds, its great. i run 35/12.5 tires on stock 7" wide wheels.

 

I have two trucks with the same set up and have never had an issue with either one of them I SAY DO IT!

 

i have 15 by 8 on a 35 12.50 km2 and aired down to 3 psi no problems

 

NIMYAD......how do you like the KM-2's?? On the same note of rims, i also need to find a good brand of tire for a DD/ Moderate trail rig. I like the KM-2's but wasn't sure how guys liked um?!

 

i love the km2's. smooth on the road, great off-road. i wen't up a 10 mile creek run with big rocks no problems, also led the way through 3 ft of snow with no lockers.

 

you running beadlocks @ 3psi?

 

no, you don't need beadlocks if your unning the 12.50's on a smaller rim, I've ran 35x12.50's and 33.12.50's on 8 inch rims, it's my rim of choice Becaue I can air down so much

 

You're lucky - flirting with disaster.

OP,

Running a 12.5" wide tire on an 8" rim is fine.

not quite, i used 12.50" wide tires on narrow 7" wide rims and also prefer it over a wider wheel. I ran below 10psi every time i hit the dirt in my '88 pickup.. in 8 years of california rack and trail running I had a bead pop off once, my front brake line busted on a 5' drop off at a bad angle with 5psi on 33/12.50r15 procomp M/T's. that is why i always carry a can of starting fluid, instant inflation..

but 2 people getting lucky isn't that uncommon. in your work, you should know this more then most.. (and thank you by the way)

 

Not really, I usually stay around 8 psi, and here in Florida there are no rocks, in Colorado when I used to live there iwould pop it off occasionally, but I wheeled a K-5 and it's a bit heavier, so I had to adjust my amount of air to compensate for the 4 tons...;p

 

/I also wheel a full size rig and 16.5" rims with 36/12.50 and would not recommend lower then 19psi per tire. the weight does not allow it.

 

I'm glad to know some people still know how to wheel their rigs then.

I've seen many a rig trapped on a trail with a popped bead because of narrow rims with no bead locks and a heavy-footed driver.

you guys are lucky...have blown several beads on 8" wide rims with 33's & 35's in the 8-12 psi range...

 

nope no beadlocks. the other people i run with have 35 12.50 or 13.50 with no beadlocks on a 10 in rim. rarely ever pop of beads. gone down to .5 psi (yes .5 psi) before in the snow too. nk. in the past 3 years we've destroyed more sidewalls then we have blown off beads. we're all running aluminum wheels too, seem to hold the bead better then steel

 

That's insane.

ya i agree it is. but it works.
