Guys - This may be one for the record book of dump questions.

But I have a tandem axel trailer towing about 7k.
Has a max load tire pressure of 65 PSI. Do I want to tires at the max load pressure?

What is a good PSI - when I check the all looked firm and were around 50 or so.

They was not other pressure rating on the tire so I guess 65 is what they want but just seems a bit high.

I would run them at 60psi cold.

This is a NO brainer !!!!!!!!!!!!!!! If the tire calls for 65 psi put in 65 psi !!!!!!!!!!!!!!!!! or carry a good spare x 4 and a jack .

If you're running at highway speeds, the 65psi pressure results in less tire deflection and therefore builds less heat, which is a tire's worst enemy.

The load your tire is capable of is determined in large part by the tire size itself, so the tire pressure that meets the load capacity depends on that. At lower speeds at a lower pressure, if you're towing short distances to a launch ramp, would result in a more civilized ride over bumps, but it's important to make sure you have enough pressure in the tire to meet load (again depending on tire size)

I would hope it meats the load. - Wow sounds weird to say

Each tire at max laod 65 PSI is rate for 3950 lbs.

The most I have ever gone to launch is about an hour so nothing real excessive here.

You guys impress me.

Good advice from all these guys. Tire pressure is the most neglected maintenance item. I always test my tire pressure cold, (less than 5 miles running), and put it at the rated pressure on the tire. An underinflated tire will run hot and wear out prematurely. Watch out for signs of age, like small cracks around the bead. Dry rotted tires are the ones that leave you out on the highway.

always run them at the cold psi pressure printed on the tire.

Earlier in this summer I set out for the boat ramp for the first or second time - looked back in the middle of a fairly sharp turn and both tires were flat and had pulled off the rim as I turned. Needless to say all 6 were underinflated - learned that lesson the hard way....

I check our tires before every trip and $hit still goes bad . We had to replace all 6 tires on our 2007 trailer only 2000 miles on them F--- a Carlisle tire .

Stay far awayfrom the Carlisle tires. Out here on the west coast, you would not believe the horror stories from guys running these on their toy boxes.
