Hello everyone. Please help this confused newbie out!!! (Long explanation incoming)
My husband and I bought a Class C motorhome in September last year. We did lots of research and thought we were going in at least somewhat educated.
We took the MH to a tire shop and had the tires checked and got a new spare as the old spare was obviously dry rotted. Our first main outing we had a blowout on the drivers side back inside dually. Getting the tire change was a wakeup call on Roadside. The blow out also cracked our grey water tank and ripped our gas cap off! Got to our destination and picked up a new spare. Once home we took the RV to an RV shop and had full inspection, oil changes and 6 new tires put on.
We also ordered a TPMS.
We got the TPMS on the front tires and outside duallies and the passenger side inside dually (pain the the butt because there is NO hand room and the valves sit so close to the rim so we were not even sure we got it on good enough). We had a trip planned and decided once we got back we would go to the tire shop have them remove the outside dually and put the TPMS on the inner dually.
On our way home from our trip the TPMS goes off for the one inner dually we have the TPMS on saying its at 20PSI. We pull into a Lowes and check the tires. Everything looks good the moniter in still on it the tire looks fine (brand new tires with maybe 200 miles on them at this point). We think maybe we got a bad TPMS sensor.
We drive the remaining 60 miles home taking it easy going no more then 60 MPH.
Hubby decides we need to get the dually valves replaced with the long metal ones so I call the tire shop. They will do it but we need to order the dually valve kit. I have ordered that and it will be here next week.
Now I am reading all I can on dually tires and how to check air pressure and read about wacking the tire with a stick and listen for the difference in sound. So i go outside and whack the tires with a stick and sure enough the inner passenger dually SOUNDS DIFFERENT
Now I think we may have drove about 60 miles home with a low PSI on our inner passnger tire. So my questions are:
1) When the valves come in and I take the MH up to have them put on do I ask them to inspect that tire? Tell them we drove it 60 miles with it possibly being very low? Replace that tire? Inspect the outer tire on that side?
2) What tools do we need to have to be able to keep our tires in good condition and to check for problems? We have a TPMS but being newbies, knowing that our tire was brand new, and not seeing a problem we assumed maybe the sensor itself was bad instead of trusting it and assuming the tire had indeed lost pressure.
I am terrified of another blow out and I thought we would be good to go with 6 brand new tires!
