ST Tire "Plies" Question and a PSI Question

Thanks guys. Ok I will run them at 65 lbs even though they will not be "worked" to that level of weight carrying. I was worried about the middle of the tread wearing from "over-inflation" and maybe the trailer being bounced too much back there.

Yes, I have the "Radial Trail RH" tires and the "plies" are as marked on the tire is as stated in the OP.

The 12 year old Marathons lasted this long because they were mostly out of the sun and only had about 10K miles on them. However they did have a couple of flats from nails/screws and one with a sharp rock that needed a patch, so one of those repaired ones sort of disintegrated the other day. People were passing me beeping and pointing, so that was my clue! Pieces of tire going from my trailer as seen from the driver's side mirror! Luckily I got to a road-side turn off spot before the wheel rim was damaged.

Saved by Good Sam since I didn't feel like changing the tire with my spare (which I could have with a lot of work) and I have paid up to Good Sam over the years so I thought I would just get some of my money's worth. :) (Thanks, Mill Bay Towing)

Anyway, after that little episode, I got all new tires figuring my luck had run out on those old ones! (Instead of getting just one new one) It turned out that local shops' availability and prices left me no choice but these Carlisles. (at KalTire) I figure I can ignore the usual "issues" on that brand because of the low mileage they will ever get.

At this point there are not any issues on the NEW Carlisle RH. FYI-The old tires were Carlisle Radial Trail. The NEW tires are signified by the "RH" designation after the name. The tread design is similar too. They improved the tire but did not purchase new molds for the new design. If you go here it looks like subtle tread pattern differences-Clicky

Some of the images are of the old tire-some are the NEW tire.
