Every year at our annual irv2.com national rally the committee offers free rig weighing, which includes individual wheel weighing. I've known about this ever since attending our first rally.
The importance of knowing my rig weights came to the forefront last month when all four ST 235/80R16, LR "E" tires failed (ply separation). We stopped at a tire store for replacement tires, where they said the tires failed from over-loading/underinflation. Three of the tires were still inflated, one deflated; they still registered 78-80psi after sitting overnight. I showed my completed irv2.com weight form to the owner. He inquired where I got such a form so I told him. He then stated that was the first such form he had ever seen, and I was the first RVer to ever know my individual wheel weights.
Since that tire shop did not sell Triangle ST tires, I just left them there and the owner hand wrote a letter stating the tires failed from mfgrs. defect NOT overloading or underinflation.
The downside_ the original selling tire shop says they will only warranty 1/4 of tire cost because of tread wearl
The unusual tread wear was caused by ply separation!
Moral of my experience, know your rig weights!
Our 5er now has four new Sailun LT 235/85R16, LR "G" tires. Sailun tires are built by Sigma Tire to compete with Goodyear G614 tires.
