Tire Pressure

[97t4rnr]

Just had 4 new Pro Comp AT 285/75/16's put on the 4Runner.

What inflation pressure is everyone running in their 285/75/16's. Currently I'm at 35 PSI, but want to get the most out of the tire.

did you read the side of the tire re max tire pressure? hard to give you a number without it. also, depends on what driving you are doing. higher pressure for better fuel mileage, lower for cushier ride and offroading. so what im' trying to say is, you determine your own psi within the psi rating of your tire

32-36 is a good place to be between. I've seen some go above 36 but like Bob said the ride will get firm.

i ran mine at 40 for about 3 miles, couldnt stand the ride. now i run at 35, and its perfect. offroad im down no lower than 12

That's probably right around where you should be on a tire that size. The larger the tire, the more pressure you'll need to run to keep the tire feeling responsive yet keep the ride from becoming harsh.

I'm running 50 psi all around in my load range D Revo's, and admittedly the ride is a little rough (but I get good mileage in the process). Max PSI on these tires is 65, btw. At 35 these tires squat too much for my taste on-road, and I lose 2-3mpg. if I wanted a softer ride, I would go to 40 or 42 probably.

Off-road is another story, about 20-15 psi depending on terrain. The 16" rims make a big difference in usable pressures, I used to run 10-15psi on my '92's 33x10.50's (under 10 in the sand), but they were load range C and on 15" rims. I'm not sure I would be comfortable going under 15psi on these 285 Revos.

I have to say, I am VERY impressed with the wear on these things. Their traction is average off-road, but they have almost 60k miles on them now, and still have usable tread (although not much). When deciding on a running pressure, always be mindful of uneven treadwear patterns, too much or too little and you'll lose tread life.

Max pressure is 65PSI. I just wanted to find out what everyone was running in their's so I might be able to maximize my fuel.

Thanks for the input so far.
