Got new trailer tires and valve stems last summer. They were OK for a while,now two of them leak around the stems. What can I do other than dismount the tires and work on the holes and put in new stems.I'm not opposed to slime or any other product but will that get up to the stem.

ou can try slime, etc., but when you finally bite the bullet & dismount, you have a mess & some of those flat-fixers rust the devil out of wheels, essentially ruining them. Dismount, grind clean around stem seat, paint & it will hold air. Check bead seat while there.
 

Assuming those are the normal rubber valve stems and not the metal ones, I went through that on a car. They were a bad lot of Chinese valve stems. If they were recently installed new, the dealer should replace them. I would take them back to the dealer. If they are the metal ones, I would thing they could be tightened. I could not put the metal ones on the car, different hole.

You say it is a trailer??? Then put good STEEL valve stems in them. If they put the pop in pieces of crap from China they will keep leaking. The steel ones have an oring and rubber washer that sandwichws the rim. They do not leak very often. They cost a few dollars where the cheap pop in ones are less than a dollar.
 
Agreed. Local tire dealer, neighbor, put steel ones on the pickup last time I got tires. Said he was having a lot of trouible with rubber one's. Didn't charge any extra, said it was worth it to him to not have to fix a bad rubber one.
 
something like this just make sure the installer knows how to do it. I bought a new pair of tires once and they leaked from day one, not to bad but had to be checked before hauling heavy loads. When I went to a different place to have a set of tires for the front, the guy checked the others and said they were put together wrong he fixed them and they never leaked again.

I had a set of new name brand tires on my F150 a few years back that were *leaking through the side walls*! The local dealer replaced 3 of them - (separately, of course!) but just couldn"t justify replacing the last one - which also leaked down.

That was 6 years ago in NC. It was an old company with a good rep at the time. A while back I heard they were having some problems staying in business.
 
I have taken the old ones out cleaned up the rim /wheel around the stem hole then put silicone on the stem and reinstalled it or used new ones. That sealed it up. Just use enough to fill the groove in the stem then pull it in. The silicone seems to seal there. I inflate immediately.
 
They make a slime-filled tube for smaller tires. I've got them on my little fence row sprayer cart. The package said that the slime only works in the tread area, so I'd think it wouldn't help your valve stem leakage. When I was a young man and worked in the local filling station, we always dipped the tubeless stems in a can of sealer before we installed them. Don't remember the brand name of the sealer, but it was meant for troublesome situations where the tire didn't want to seal against a less than perfect rim. I have to agree with the others who recommended the metal valves though. I've got a couple of trailers with those valves, and they've outlived several tires.
 
We put new drives on the semi and they all leaked. Ended up pulling all the tires to tighten the valve stems. Shop didn't have them much more than finger tight.
