2017 FORD F-350 Tires Problems

I have experienced multiple issues with my wheels valve stems leaking. I have gotten a couple stems replaced and the problem persists. I am adding air to my tires nearly everyday. I have read a lot of threads online with owners of the same year, make, and model are having the same problems. This is a safety concern because my family and I use this vehicle for travel and I cannot be having flat tires or be stranded because my tires won’t hold air. This truck has been to the dealer multiple times for this. Ron Tirapelli Ford Shorewood IL. The vehicle was also purchased there. I receive warning lights for low tire pressure regularly.

The VIN is from my tow vehicle, your system wouldn't take the VIN of my Fifth Wheel RV (4YDF37329J4700954) which the tire that failed is installed on. The tire in question was purchased in April of 2021 and had approximately 500 miles on it when the tread separated from the tire and became wrapped around the axle of the RV. The tire is a Sailun S637 ST235/80R16.

The Tread on these tire started separating prematurely. I Purchased 4 of these at the same time and fear the others may do the same. Others using the same tire with similar manufacture dates report the same issue. Tires are being used on our Fifth Wheel Trailer but the previous page would not recognize the Vin. That vin is [XXX] Tire Size ST235/80R16 INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
