Watch the outsides of your treds and side walls.....

 

You belted your daughter in both seat belts.

Hahaha, that's so funny! Strap 'em down and keep rollin!

 

I have 275/65R18E and i run 41psi on the road and 25psi off road. Anything over 41psi has been extremely rough and I would be too nervous to run anything less than 25psi off road.

My gas mileage is averaging about 12.5mpg and the tires haven't worn at all in 2,000 miles. It does ride a little rough but I almost never have anyone but me and the dogs in the truck and they never complain - LOL.

 

How about running Discovery Discoverer, size 265 65R18?
Beefy tires and they rub a little turning tight. I'm getting 14.2 mileage at it's best running max 50 psi.
The ride is very stiff. I think I may loose 10 psi and see how the ride is.

40 pounds all the way around seems to work best for most people.

 

Don't ask on the internet for what the proper tire pressure is.

Unless someone is running the exact same vehicle equipped the same way with the exact same time (this doesn't mean just the same tire size), you're wasting your time beacause any answer is pure guesswork.

There are only three ways to get the correct tire pressure.
1. Call the mfg, provide the tire specs and your axle weight and ask them the correct pressure.
2. Mark a section of the tread with paint and roll your vehicle over a clean spot of pavement and adjust the pressure and repeat the test until you have an even tread pattern.
3. Drive the vehicle and use an infrared thermometer to check the tread temp across the tread, adjust pressure and repeat until the temp is even across the tread.

You'll get better mileage the higher the pressure you run, but the tradeoff, if it's higher than ideal, is quicker tread wear, less traction and rougher ride.

Started off at like 45 PSI thanks to the friendly tire install folks. Took 'er on a road trip and got good mileage, but ohhhh man was it shady as F*@%. Looking at the wear pattern (chalk/paint/dust) I'm now at about 36 PSI all around. Think I may have to go a bit lower up front, and maybe go up in the back. Time will tell. Still trying to work "the importance of correct tire pressure" argument with the better half so I can get an air compressor. Hoping she doesn't notice both an on-board ARB and portable compressor in the garage.

 

Run your tires at 40 pounds all the way around , when off road and you want to air down drop to no lower then 30 for better traction and a smoother ride.

 

Well, it's an easy argument. proper pressure means proper tire wear means longer life means less money. It also means safer driving. Who can argue with that.
Keep checking as you are to get the correct pressure. You're on the right track.
