I was wondering the same thing?

My fire dept. Just got a set of used 14.00 X 20 wheels to put on our 5ton we use to haul water with. Problem is most of the wheels leak air. I personally am not familiar with this rim system. is it just a matter of braking them all down and then reinflating or is it more then that? what's your thought? Thanks

My M813 (governed 2100rpm) will run around 65 on 14.00's. Hard to know exactly, because my speedometer only goes to 60..

However, at that speed I feel a bit like a missile, and I don't like that.
I have found that the truck "likes" 57mph indicated, as in, if I drive on the highway and don't look at the gauge a lot, it will almost always be at 57 when I do. The truck and I are both quite comfortable cruising at 57, and will do so without a hiccup for several hours at a time.

That said, when I go long distances it is usually to a show and in company with Deuces, so cruise ends up being around 52mph. (Or 48mph if one of our members is in the column, he has an 'anchor' deuce..

)

Cheers

DLC, not sure what type of rims you are using. 5 ton super singles & HEMIT rims are bolt together tubeless. Leaking can occur at the large O-ring or the valve stem. Most likely the O-ring. These can be converted to tube & flap type but the rim has to be modified.

I had to replace a bad "O" ring in one of my wheels. Got the ring from Memphis.
It was a lot of work, but not terrible. I have an old forklift which helped a lot. The beadlock was a pain too, but I'd do it again before I'd pay someone else.
