Trailer Tire Inflation System...Ever seen them air up a tire broken loose from wheel?

YES!!! Hendrickson HTIS (earlier generation of what is now TireMaxx). Tire flat first-thing in the morning; fellow at the tire shop 20 min away thought I was a nut when he came out and found all tires were up. Oneperfectrun - were you running aluminum rims? My regular tire shop they will break loose easier than steel rims when one goes down.

 

You may want to reconsider running a van with a flat , don't quote me but I've heard with that stupid new 2010 CSA its a 6 point violation . But in all seriousness not sure why you would want to run with a flat tire to begin with ? Under a heavy load you risk destroying and chunking an aluminum rim ,furthermore the tire could inadvertently not inflate and come off bouncing distracting an oncoming vehicle or hitting one and god forbid a motorcycle is in its path . Just some food for thought the next time you don't have time to have it properly inflated with an air tank made for this , of course back in the day and even today people use ether starting fluid to pop the tire back on its rim . I don't suggest it as it can in the wrong hands be dangerous but it can be done. Good luck ! Happy 2013 .

 

Yes, it has happened to me also. I was shocked that it would seat a bead and air up but it sure did.

 

i had a completely deflated tire after sleeping all night. i decided to drive 5 miles to a tire repair shop to get it fixed. when i got there to my surprise the tire was fully inflated.

 

The trailers I pull have them installed and it must be how they are setup as they are practically useless. They will stop filling the tire when the pressure falls below 84psi. The hoses that run from the hub frequently leak and will keep leaking air until the tire is flat. the hoses get "plugged" so you can't add air or check pressure without removing it.

I suppose I'll just have to find a manual on them to figure out what is going on.
