Correct Tire Pressure
#13
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.

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.

Keep checking as you are to get the correct pressure. You're on the right track.
