Rough Ride
Last fall, I installed a set of Sailun tires on my Montana, upgrading to G rated tires. I’m running only 90-95 pounds in the tires. They are shaking the camper quite a bit. Last week, we cravked th...

If a tire is rated for 110 psi and ran less psi, wouldn't this cause a issue due to "under inflation"? Still think a name brand E ply LT tire is best bet. Ran LT's on our '06 Cedar Creek (13,800 fully loaded) at 80 psi for 12 years and no probs.
I ran Michelin XPS Ribs and Bridgestone Duravis R250s on our 12,400 lb 5er for years. Original LT235/85R16E china bombs called for 65 psi. I found that the Ribs were wearing a little more in the out edges so I upper inflation to 71 PSI and had even wear. Inflation is based on the load the tires actually carry, not their maximum inflation. In several calls to Michelin, they always stated that over inflation for the load carried can lead to impact damage and reduced braking ability.
Tires state MAX Load XXXX at YYY PSI. On passenger car and LT tires there on inflation charts that are universal across all brands for the same size and load range tire.
Along came cheap ST tires and it is my belief that inflation to max side number is just a bandaid that manufactures tried to stick on the tires, because high failure rates. Finally after many years there are now better ST tires available.
Inflation charts for ST tires seem to vary by manufacture if they exist at all, as they comply with different standards(think lesser).
Still a little puzzled because most blowouts from what I gather are due to underinflation.
