Ply Rating
Having all bearings replaced. Discussing getting new tires with mechanic. He was saying that the higher the ply rating, the more heat the tire generates/holds? Make sense. Still, thinking higher the ply rating, the safer the tire. How high a ply rating do you think I should go with? Thoughts? 21,000 GVW on triple axle Voltage. Thanks
Rusty

If sticking with 16" tires here is what quite a few have gone to Sailun ST 235/85/R16 which are 14 ply load range "G". In a 16" I'm fairly sure that's the max load range made. My 17.5" tires are load range "H" 4806lbs rated.

Rusty, I just went to the Sailun ST 235/85/R16, Mike is right, its a 14ply tire and I just came back from a run to AZ, which I put about 2K miles on the tires, because they were new, I watched the heat and it was lower then the China Bombs and I ran at 70, where I ran at 65 with the China Bombs....

After delivery of my 3970, after a few dry runs locally for weekends and such, We are going to go the route DesertRat did...17.5 inch rims with the Hankook H rated tires. Costly? Yes, but needed insurance to help with the longer road trips we intend on doing in the near future.

With me only putting on 5 or 6 thousand miles a year (Sturgis and Florida), I'm going to keep the 16" and also go with the Sailun ST's sometime this year. I was wondering about the ply and heat (14 significantly hotter than 10 or 12's?). For what it's worth, my Westlakes' (I check them every gas stop) only heat up to around 105 degrees, which is pretty good I think.

I wouldn't be concerned about heat. Heck it's 105 here today and I'm not towing just riding my Burgman home from work in another hour.

Rusty,
I've always heard the reverse, the higher the ply, the less tire squirm. Less tire squirm means less friction and less heat. Another contributor to tire squirm, is the rubber compound and tread depth. ST tires (properly constructed ST tires) have a harder rubber compound and a shallower tread.
I don't like the numbers games that are played by the RV and auto industries. I've never had a problem with anything that is over built, can't say the same when the liars are figuring the figures that don't lie.
In addition to the increase in ply rating, I went from a 235/80 to 235/85 16.
Here's a FAQ on ST tires from the Goodyear web site. Goodyear RV Tires – Frequently Asked Questions
Somewhere in the flotsam and jetsam from the www thing I have a more info on ST tires I'll try to track it down for you, but this also has some good info on the ST vs LT tires topic. https://rvingwithmarkpolk.com/2012/1...s-vs-lt-tires/
I'm just putting this out there for folks to do with what they wish. I'm certainly not trying to start the ST vs LT tire debate AGAIN.
