Jack up before adding air?

I STUPIDLY hooked up the 25 ft camper THEN checked the air in the rear tires of the Tahoe.
They read bout 35 psi and are a tad flat looking.
Tires are rated for 42 psi at load.

Should I use the jack to raise the campers weight off the Tahoe before adding air in the morning before taking off.
It's 1.5 hrs away.

No need to raise the weight off the truck ; BUT you need to add air before you move and the tires start heating up. Under inflated they will heat up FAST.
Do you know what the weight on the rear axle is with the trailer hooked up?
How does that weight compare to the load rating on the tires?

Thanx Dex

No Skip, I don't know axle weight, but do know the tires are rated highter than the load.

Its about 3 miles to the air station though.

I'll re-measure before and after that lil hike to know how much it went up.

If one tire is at the correct pressure cold. When you get too the air station check it again.
And put the same amount in the low tire.

Get that tire checked. There is a reason why the pressure is down. Adding air is not going to repair the tire. You are flirting with a dangerous situation here.

Suggest you buy a decent 12V air compressor.

What kind of a tire is it (size, ply rating, etc.)? 35 psi is probably not underinflated, just because it requires more pressure at maximum load. Three miles is no big deal, get in it and drive to your air source. Check the pressure there and add 7 lbs if you want the 42 psi maximum pressure recommended at maximum load.

They look low because:
1. They are radial tires
2. You have the hitch weight of the trailer on the rear of your Tahoe

I suggest you check the air pressure with the 25' camper on the ground and then lift the wheels off the ground as you did before and check the pressure again....

The tire pressure will not change at all.

Try it.

Air pressure inside the tire is constant, regardless of the load. Higher load just makes the footprint of the tire on the ground larger, but internal pressure is the same. When higher load, use the higher pressure, it is better for the tire.

I curious, do you jack up your car or truck before adding air?

Well, I added air at the pump a few mi down the rd in town. Bumped it up to 44 psi as the tire says for max load.
Rode fine, except for the winds at 30 mph off and on the whole ride.
At least it was only bout 2 hrs away.

Thanks to all who contributed.
