I've only taken it out 5 times and all of those trips were 1.5 hours each way, so not a lot of miles. One was a freak blowout, the other I don't know. While the tries don't look bad, they are obviously the originals, so time to change. I was reading your post about the Sailun brand. I also don't want to pay $500 p/tiire.

I have an interesting dilemma. My model's specs everywhere - even Keystones site and brochure - say I only have 2 axles and 4 tires. Even the pictures show just 2 tires p/side. my 2019 380TH has 3 axels and 6 tires. Can't find anyone to explain that, but it is what it is.

This is what is currently on the RV,

Manufacture: Rainier ST
Series: ST 235/80R16
12 PR load range F tubeless
Max load single 3860 pounds at 95 psi cold
Max load dual 3420 pounds at 95 psi cold
Tread 2 steel +3 polyester +1 nylon
Sidewall 3 polyester

The tires you mention are G rated and 14 ply. I was going to go with 12 ply, but obviously would prefer 14. I realize you can't tell me if those tires are a fit for me, but at the price I find them listed would probably let me get 6 tires replaced and balanced for under $1,500.

Anyone have thoughts?

In your case I would install 6 Sailun S637 14PLY tires in 235/85 x 16 tires and run them at 90 psi.
