Trailer tires for jayco 1992 1006

Hi, not sure if I'm in the right section but I have Carlyle USA Trailer tires with my pop up camper. Specifically, 5.30-12. They're rated at 80 # psi at maximum load of 1050 pounds per tire. If my camper and load weighs approximately 1500 pounds, does that mean each tire should have about 55 pounds of psi? In other words about 70% of maximum load? Any insight would be appreciated. Right now my tires have 32# each. Thanks everyone.

You definitely want more than 32 # in your tires. Most load/inflation charts for trailer tires show a proportional inflation pressure based on load but not necessarily a direct proportion. I have the same 5.3X12 tires on my Jayco 1006 with the same load/inflation ratings. I've actually stripped a lot of weight off my camper so I'm estimating it is abut 1,200 lbs. I still plan to run about 60 psi (I haven't taken it on the road yet). I haven't tried this but I've been told that you can rub chalk on your tread and then drive around a bit to see how the chalk wears off. If it only wears in the middle then you have too much pressure. If it wears evenly then the tread is staying flat all the way across and that is about where you want it. If it wears only on the outside edges then you don't have enough pressure.

When we had our pop--up I always ran the tires at max. Heat is your enemy and 12" tires make a lot of revolutions at 60-65 mph.

Trailer tires should always be kept at maximum inflation. If you do not the sidewalls can flex, and cause terrible sway.

Even on my small utility trailer, I always keep 80 PSI in the tires.
