What psi do you air your 285's to?
Called Firestone for the recommended psi for a 285/75/r16 tire and theytold me to put whatever I wanted in, they didn't have a recommended level. Right now they are at 45 and look fine but can they go higher? What do you guys air'em to?

I've been thinking about starting a tire pressure thread. With the price of gas I've been trying more and more pressure in all my vehicles. With my truck (33s) I'm running 43 psi cold, which gets over 45 psi hot. So far no problems.

What kinda rims are you running? I have 285/75's on my stock 16 x 7(?) wheels and if I inflate over 33 psi I will end up wearing just the center of the tire. I did the chalk test to make sure I was getting an even foot print; turns out about 32 psi is my magic number.

I run my Cooper STT's at about 43-45 psi, they wear fine in that range. Higher and ride quality suffers greatly (and wears poorly). It was suggested by Cooper rep that I run around 50, but it seemed too high for 4Runner (versus a truck that they would normally recommend pressures to)

I have collected some tips on determining proper tire pressures on the web page below:

I highly recommend the chalk test 4Crawler has on the website.
Remember, everyones truck, tires and load is different-so no one will have the same pressures you do. My T100 is heavier than your truck, I have 31's and run 41 in back and 38 in front, max is 50psi.

I am running Cooper STT's 285/75/16 on my stock Taco wheels (16x7) and am currently running 32 in front which seems perfect, and 30 in the rear and am not riding on the whole tread. The edges of the tire are not contacting. i am wondering how much lower I should go as there is just no weight in the back of a Taco and I even have a 140 pound canopy on it..

30psi is about right for me, but I upped it to 35 to see if I can improve mileage a bit. Jury is still out on that. At 35 I expect to see the center of the tire wear faster. I run them between 12-18psi on the trail and around 8-10psi in the sand.
