My old Goodyear Marathon tires on my 34' Jayco were getting some age on them, so I decided it was time to replace them. I tried to do a lot of research on tires, but seemed to get more confused, the more I read! In the end, I settled on 205/75/R14 Goodyear Endurance. I read a lot of promising things about them and coupled with the fact that they're not made in China, I figured I'd give them a shot.
The sidewall indicates that they should be inflated to 65 PSI. The sticker on my trailer, however, states that my tires should be inflated to 50 PSI. My concern is that I've read that under-inflated tires tend to build up a lot of heat. So, on my first run with the new tires today, I left them at 65 PSI and drove two hours. Within about 25 minutes, my tire pressure monitoring system showed their pressure at 73 PSI and the average temperature of the tire at around 97 degrees. Those numbers stayed consistent for the duration of the trip. In case it matters, it was in the mid-80's for the outside temperature and my trailer's weight is usually just a little under its maximum of 7,500 pounds.
So, my question is this: Should I continue to run them at the tire manufacturer's recommended pressure of 65 PSI, drop it down to the trailer's recommended inflation of 50 PSI, or inflate them to some pressure in between? I'd really appreciate any insight or advice anyone can give me.
