Tire valve Stems

Use metal ones, with urethane gaskets.

I have the metal duly kit, easy access for airing and TPMS.

getting old if they have been in that long.

All the truck tire shop did on my last big truck was replace the rubber gaskets used on the metal stems, not replacing the complete stem. That seems to me not a needed thing to do, but don't know for sure. I would ask why and maybe even ask other truck tire shops the reason for replacement.

I had mine replaced with the second set of tires, just because....be proactive. After 14 years on the coach, I figured it was time.....Dennis

$14.15 for parts and install on each wheel. Do it for the peace of mind and value. One service call to change out a flat due to a leaking valve stem will set you back a lot more than that.

Always use metal stems and replace sealing washers with each tire exchange and enjoy peace of mind and safety. Whenever we go cheap on our own projects we know who stuck it to us when we have a failure.

IF this is the first time you got new tires consider a company called Duly Valves or something very close to that.

I know on my Workhorse checking the inside dual was.. not easy

Till I had duly valves put on and then it was about as hard as the tires on my car.. Easier in fact.

All are metal on 22.5s as far as I know. The small gaskets need to be changed even if the stems themselves are uncorroded,bent n holes or otherwise damaged plus the valves inside the stems themselves and the caps.
Only stainless steel or chromed stainless steel is acceptable. The caps themselves should be the best with the rubber gaskets inside.
The valve stem caps saved us once, on the left front wheel. The valve had been loosened and pressure was down but the cap kept most of the pressure in and if tighter it might have kept all in. The disaster awaiting from a blown low pressure hot tire makes the price worth while perhaps. The trend has been for shops to use the cheapest Chinese junk. Ask to see what they install and where it came from. Freightliner put on wheel nut covers that were loose and rusted in a few weeks from rain. They had barrels full of them they damaged our originals.Said that was all they had. Called Freightlner South Carolina. They had the American made stainless ones. They didn't want to pay for them and lied. hd them order the right ones.Caveat Emptor is the rule of the day.

You can't go wrong with metal stems but if you can find stainless ones, that would be better.
