i have a question that i need help with. i have a 3h lq trailer loaded weight around 14000,00lbs. my tires are max air 80lbs. we are getting ready to start trail riding i checked them today they are at 68-71lbs.(new tires) less than 100 miles on them..my question is i have read here to run tires at max. we trail ride and camp 3hrs away (interstate driving) 90% of it.dont your tires heat up when driving at ave 65mph for 3 hrs.. if i put the tires at around 75+ are they going to be over 80lbs by the time i get to trail/camping..thanks for in input on this i have learned so much from all of you on here... happy trails

dont your tires heat up when driving at ave 65mph for 3 hrs.. if i put the tires at around 75+ are they going to be over 80lbs by the time i get to trail/camping..
Take it from my mistake... After two blown tires - an expensive lesson to me.
Yes... the tires will heat in use. BUT the tire pressure is specified as COLD inflation pressure.
Anything else will cause them to be underinflated in use. Another way to think about this is ... Why not start with an under inflated tire... the added heat will cause the tire pressure to build ... Right ?? WRONG >>> the tire will be damaged and blow out.
Here's a link to trailer tire info from a tire manufacturer.
First point is to keep the tire at max cold inflation pressure. (in your case : 80 PSI) Second; All tires lose air pressure over time. This is a point in justification of having a small air compressor (or a large compressor, good for all the air tools you'll just have to have!) at home. You can adjust your tire pressure absolutely cold and at the start of any trip.

I agree with Hosspuller, and another way to think about it is an underinflated tire will heat up faster than a properly inflated tire. You aren't doing your tires any favors by keeping them at less than the proper air pressure.

Agreed. COLD air pressure is what is on the tire side recommendation. We carry a medium-small air compressor that we can run off of the on-board generator, so that even on a boondock camping ride, we can "touch up" the cold tire air pressure to max recommended before driving off. Has been very successful for us.
