2004 HR Ambassador 38PDQ. New to me Oct 2017. Previous owner had experienced a blowout [inner curbside dual] in 2016. They installed 6 Sailun S637 275/70R22.5 tires. I've put 2,000 mi on the tires with 95psi on the drives and 100 in the steers. I used a Goodyear inflation chart and 4 corner weights. I also installed Balance Masters on all wheels. The ride was quiet, smooth, and I have no complaints.
My problem is that I can find very little info on these tires. I find a number of user posts about installations on RV trailers and 5ers but nothing on Class A's.

Can anyone point me to applicable inflation charts?

The only DOT numbers I can find on the tires is 5379 which returns an error code for incomplete numbers. Has anyone experienced any recalls or other problems with Sailun tires?

Some manufacturers may not publish load/inflation charts. There is no requirement to do so and the truckers just run them at the minimum pressure on the sidewall as that supports the maximum load on the tire.
Truckers don't bother with fide qualoty, they want best fuel mileage and weight carrying capacity.

Just google Sailun Truck tires and you will get some info.
I had a set of Sailun Tires on my gravel truck and I was skeptical at first. They were good tires for traction, ride, and I got good wear from them.
The next set the company put on were Bridgestone. They were good as well but I have to say the Sailun's were just as good and alot cheaper.
I would not be afraid of running them on a coach.

I have to replace 6 supposedly 2 y/o Chinese Hercules H-209 275/70R/22.5 tires due to a 1/2 inch deep crack in my left steer tire. I inspected all the tire sidewalls that were visible without getting under the coach. All I could find was "DOT 5379" embossed on the sidewalls. A tire dealer explained to me that the #57 denotes what plant produced the tire(Sailun in Shandong China) and #79 identifies the size of the tire in a code useful only to the manufacturer. Letters can replace some of the numbers.

Apparently, all my tires were mounted with the sidewall with the DOT date code on it on the inside of the wheel.
