Just bought my first RV. It's used with 2yr old tires.I'm planning a long trip and all the talk about the tires is confusing. My travel trailer is 28ft with dry weight of 6000 lbs.The tires say maximum cold tire pressure is 80 psi.Because the tires are ST are they safe to use with 80psi and an average speed of 60mph? Everybody has opinions but I would like to know if anybody has the same tires with good results?Thank you

Does your RV have a vehicle tire placard - located on the front drivers side lower? What does it say for size and inflation pressure?How old is the trailer? Still trying to sort this out, but it was common for many travel trailer manufacturers to use too small of a tire. What brand of tires? What country were they made in?

Because the tires are ST are they safe to use with 80psi and an average speed of 60mph? Everybody has opinions but I would like to know if anybody has the same tires with good results? Let me see if I can stand under what you are asking; The people that designed the tire have it labeled for 80 PSI max pressure, right? And you are asking random folks on the net if the tire will stand 80 PSI? The fact is it will not only stand the 80, but will not stand the maximum load unless it has 80 in it. You need to weigh your rig to be sure the tires have the weight rating to handle the load. As for speed, the sidewall will be labeled with maximum speed. your average speed will be less than that.

Topic might do better if it were moved to the travel trailer forum.

No, it’s an easy answer. Tires are 2 years old,so unless some other reason for them to be suspect, they’re basically new. If the sidewall says 80psi, then the tires are good for that, IF you need that much air in them. But look up the load pressure chart for them. I’d suspect your 6k “dry” trailer is 7k + and your tires are seeing, idk, 6500lb ish of load. 1600-1700lbs on an E tire which will be in the 2200-2600lb range depending on size doesn’t need and probably don’t want the full 80psi.
