Problem with 15.5 80 20 on 20x11 wheel

[FM5332FF]

So I brought my new wheels and tires up to my buddys shop and planned on mounting the tires on the wheels today, but i went out to eat last night with my parrents and now i have food poisoning, so needless to say i wont be mounting my tires today, so i get a phone call from my friend and i told him what was going on and he said that he had already mounted one tire on the wheel but he cant get it to air up, he said that the bead wont seat because the sidewalls are so thick, so i was wondering, have any of you had this problem? if so how did you get your tires to inflate, i have one piece 20X11 wheels and my tires are 15.5 80 20 ? what do you think?

Are the wheels designed for MPT tires or the standard bead tires? That could be the problem.

they are designed for military tires, the place that i got them from has the same wheel with a 1600R20 on it

might of got lucky with that one mounted one... any pictures of the wheels tires? also does he have a cheetah that he can use while trying to inflate the tires at first?

Where did you get the rims from?

Even non MPT tires as they are should air up (and hold air) well on MPT wheels, which these most probably are!

Maybe the sidewalls just have flattened a bit from being stored stacked…
Tell your friend to use a “bead-up” tool. It’s very simple and safe to use, and cheap to make, too! (need a little drawing...?)


Also, cold (and old?) tires are pretty stiff to work with… heat them up or put them out in the sun for a while.

Keep on trying, it’s only a minor initial issue, I'm sure!

with big tractor tires i blow a little either in them and hit it with the torch....they blow right up and then hit them with the air chuck......Be carefull............know what....I don't recomend that at all, to dangerous!!

I don't know if it would work, but on car tires I've had luck with wrapping a come-along around the tread and tightening it up to balloon the bead out some. Then take it off when you get the bead to seat.

A great trick - SAFE TOO

Here is a freeby. Take a 20" bicycle innertube. Lube, lube, lube, lube it up and put it between the bead and rim. Put a few pounds of air in it so it swells and "seals" between the tire and wheel. Now air up the tire. Pull the tube out when the tire swells to seat.

SAFE and handy on the trail.

We mounted my 1400x20 tires last week on marsh racing wheels,we had a hard time even with the cheeteh air tank.Either works also, but be careful with it.

well, when i started feeling half okay and no longer had anything in my stomach to throw up, i went to my buddys shop, the tires had been sitting for a bit of time and they were cold so we layed them out in the sun for a little bit and then used a cheetah and that didnt work, then we used alot of tire soap and that didnt work, so we did what i did not want to do and used ether, well that worked first try. so needless to say a long day and many trips to the porcelain throne with wonderful food poisoning i now have my tires mounted. there are pictures of them in my Bobbed Deuce Bed Thread, Thanks for the help guys.
