275 70R18 Tire Question

There's an easy way to sort this ought: Do the Math.

Calculate what pressure is required to carry the GAWR for the size listed on your truck.

If you do that, then you will find that vehicle tire placard will have enough load carrying capacity for the rated GAWR - even if the max pressure of the tire is more.

60 all around once the camper is parked for the year. Then I bump the rears back up to 80ish when it's time to get it out again in the spring. 80 is too high unloaded but I don't enjoy deflating and reinflating my tires over and over.

I have a clip on air chuck. Without it on an air hose it makes a great way to deflate tires. I can tell by the sound of the air escaping when it is getting to around 44 pounds(Rears empty). Chris

Offroad jeeper's have de-flators that are adjustable. However they are not settable to higher pressure ranges. Chris

I run 65PSI year round loaded and unloaded and got 56k miles on my last set of 20" tires.

It's really that simple.

Fish, what tires are you running?

I've got the OEM Firestone H/Ts and I'll be lucky to get 27K out of them. I'm a little over 26K now and they're close to being worn out. Need to try something that will last next time.

Sounds good but I'm just looking for a highway tread. Never off road, don't need ano A/TV tire
