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 three crock pots on the way home. Does anyone else experience this?

No body mentioned about getting a good air hitch either a 25k air safe hitch with the binkley holland head or a Hensley air hitch. That makes a difference on how the RV and the truck rides.

Weigh your tires, use the weight/inflation chart for the heaviest tire on each axle and add 5psi. Each axle may have the same psi or may not.

I'm betting 80-85psi.

Thanks for all of the replies. I'm going to play with air pressure a bit, and see if I can mitigate some of the issues. Selling/replacing the tires is not a realistic option, since I don't want to throw $700-800 bucks away.

Bet you could put Endurance on the same wheels and sell the Sailuns and wouldn't be OOP more than 200-300, at most.

Which Provider do you like?

Lyle

oops...slow to answer as we had a water line break and flooded the house so were in one hell of a mess around here.
Taskmaster has only one Provider ST series tire.

Taskmaster has the Provider ST and a low cost very cheap made Contender ST.
Some adds are calling the Contenders a Provider....which there not.

Check out Taskmasters products website.

I went from "E" to "G" GY's. The "E" tries were ran at 80psi because the load dictated that. The G's were ran at 85 because load dictated 80 and GY recommends when up sizing load range to add 5psi to what the chart says.

The tires wore perfectly and ride was great over many thousands of miles. Weigh your rig!

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.

BALANCE YOUR TIRES! Tire shops do not usually balance trailer tires BUT if you don't it can shake the camper to bits.

Running G rated tires at less than maximum pressure will not likely cause shaking as long as the pressure used is adequate for the trailer weight. Goodyear publishes an inflation chart for their G614's for that very purpose. On mine I run 90 psi.
