2nd Gen Non-Engine/Transmission My New Ride...... Tire Pressure ???

[sanyata]

..... well sorta !!! I just installed new Bilstien Shocks (Blue/Yellow) and Toyo Open Country MT's. What a difference. The shocks definitely smoothed the ride out a lot. The originals had about 102k miles on them. I put them on first and rode around to check the ride and was very pleased. One side effect I wasn't expecting was the rear sits a little higher than before. I'm somewhat surprised at that.

Then I had the tires installed and they just added to the ride quality. They replaced worn out 265 Bridgestone Duelers that had a far amount of sway in them. I went with 285/75/16, they're 10 Ply, E Rated @ 3740lbs max 80lbs pressure. I luv the look of the bigger tire filling the wheel well. They're on stock 2002 rims so they are a perfect fit and the stiffer sidewalls sure added to the tracking ability while eliminating the mushiness.

Now the question, with these tires rated up to 80 psi, what pressure should I run them at when running empty? I'm thinkin' maybe 60 front / 50 rear but not sure. These puppies where expensive and I wanna make 'em last so whadda you think?

TIA

I have a 2001. 5 Standard Cab and the factory 265 Mich's. I run 57 in the front all the time and rears at 42-44 empty and around 67-70 with the 5th wheel. Wearing fine. Drives trouble with 70 in the rear empty! SNOKING

That's about what I run. It all boils down to tire wear when unloaded. As long as the tires don't overheat and the contact patch is right, you should do OK.

Thanks for the feedback guys...

Snoking, are the 265 Mich's rated at 80lbs max pressure like the Toyo's? I'm just wondering if being 10 ply / 80 psi would require a slightly higher air pressure than an 8 ply at 60 or 70 max psi.

Rated to 3415 lbs at 80 lbs of air, which is over the rear axle rating of 6084, which matches two 245's at 3042 each. The 245's were the stock tire, and the door sticker matches that. 265's were an optional tire. SNOKING

So, you just divide the axle rating in half to get the tire rating needed to support the max axle load rating? If that's correct then anything over that rating would just be an added measure of safety I guess.

Thanks for your replies!

I have been running 285's on my 97, Yokohama's. I usually run the fronts at max pressure because of the weight up there. Then for the rears I will lower the pressure, run down a dirt road, then some ashpault for a little bit and take a look at if the whole width of the tire is contacting. Then if I am going to haul something I will air them up to the max just to be safe.



You will have to let us know how you like the Toyo's, I have been thinking about getting a set of them myself, they are the highest rated 285 I have found, granted I havn't been looking hard.
