If not, they would probably only last 100,000 miles!

Question for you other "truck" tire users
What kind of pressure would you recommend for my "H" Range, 285/70R19.5's?? I have them at 100psi right now, and traction isn't a problem, but ride is. Just wondering how low I could go without sacrificing too much tire life??
Thanks Guys,
Chris

Really...don't have any swaying or cornering issues, even empty??
I might try going down to 60psi and see what happens..I don't really need to go down to 35, but we'll see!
Thanks Guys,
Chris

With these tires, they are so stiff, you need to factor in what they were designed to do. For example, my tires were meant to haul up to 6K per tire at 75 MPH. On the rear, they have about 800 lbs. on each of them; 13% of there actual capacity therefore you could run 13% of their max psi rating (120). 13% of 120 is 15.6 so you could run these down to 16psi and you would be within your limits. These tires are 16ply! You need to air them down just to get some flex in them!
I can tell you right now, go as LOW as you possibly can in the rears. the difference in ride and traction is night and day!

Well I never thought about the percentages like that...I assume you'll air yours up when you hook to your trailer? I never know when I might need to hook to something, so I won't go too low as to not be safe when I'm loaded.

That's why I went to 25psi instead of like 16. This way, I can go up to 6000 lbs. on the rear tires and that would require about 2500lbs. worth of tonque weight which is more than I will ever have since I don't tow with anything other than bumper pull. I think 30-35psi in your case would be perfect.

With the tires aired down, I notice no difference between them and the stockers and after my Thuren suspension is on, it will be like an escalade.

TOTALLY agree. That's why I am doing the 295s. They not only are wider by 2", but they have "beefier" tread on them as well. If you want highway tires, Michelin makes a 295/60 tire that is beefy and will fit on a stock heigh truck. It's just not for "bad" weather.
