Check your valve stems!

Well, it happend... First flat on the trailer.

I got new tires when I bought the TT 3.5 years ago, I opted for 10-ply to replace the 8-ply that were shot. Took it to the local Goodyear shop and they provided the tires and did the install. Well my last trip, I decided to air them up to the max 80PSI (I had been running them at 65) and 30 miles from home, I saw the tread of my tire fly off in my mirror! I was able to get right over to the side of the road and stopped with no further damage than the tire. Long story short, got to les schwab and got a new tire. They found the cause, the Goodyear shop used rubber valve stems instead of metal, and the valve stem blew out. The rubber ones are only rated for 65PSI... Go figure! They put a metal one on there, and got me on my way (after setting all the tires to 62PSI) Now I just gotta get the other three changed out...

  • Seriously? so rubber valve stems won't take the 80lbs? I just bought new tires for TV. Should I be going back to tire shop and telling them to put on steel valve stems? there is rubber on there now. It's a max air pressure 80lb tire.
  • I didn't know that about the stems! Learn something new all the time.

    Hbill, what tmps system do you use? I have been looking now.. Ha!
  • I've noticed that my TPMS seem to be beating up my rubber valve stems.
