Finally got some free time today and ran the Vengeance up to Snider Tire here in Raleigh. They're a heavy truck tire shop and some really good guys I've dealt with before with our city fire trucks.
Upon pulling into the bay, they were quite certain my stems were not the full 110 psi stems. At 90 psi, you could take your finger and push the stem sideways and it would start leaking. Looking at them closely, it seriously looked like they were about to bust through the wheel.
They are TR801HP stems. That's 100 psi rated. But as I said, 90 psi was giving them fits. The shop pulled all six wheels and installed new 150 psi stems. They look great and I love overkill when it comes to issues like this.
Then they only charged me $6.50/tire to install the new stems. That was the price of the stem. They wouldn't charge me the dismount and mount fee of $25/tire because they never had to dismount the tires to install the new stems. I told the guy I felt I was cheating them.
Headed to a state park this weekend for a little getaway with the wife. A tire problem is definitely not a big concern for me now. I have emailed my dealership and explained what all happened and how disappointed I am; especially since I was charged $50/tire to have the G614s mounted before buying the camper. That's $50/tire for improper valve stems, only 70-80 psi in each tire, and the Equa-Flex hangers screwed up when they put the wheels back on the camper. Fortunately, I have fixed all the dealer screw ups I know of. At least the camper itself has been awesome!
