My Hankook 265's

They say 80 psi on the sidewalls, I suppose b/c they are 10 ply or something like that. What should I be running them at? The dealer took them down to 35 and told me they were at 60 (Discount Tire mounted them) What I am looking for is the best psi for gas milage/anti-wear, etc. Any suggestions?

Due to the size your running i'd recommend keeping them at 35 psi. The 80 psi on the side wall is the max psi for that tire. I have the same size as you and im running 35 psi and have even tread wear. If you want you could alway run it a little higher but I wouldnt go over 38 psi. Thats just my .02

So it's ok to run less than half the max?

Different size tires require different PSI to keep proper inflation. As 07 said, 80PSI is MAX and it is so high because of the ply rating. I have found that 40 - 45PSI is a good pressure to run that size tire. However 35 would not be too low because a tire with a wider surface area would not require as much pressure to provide the same amount of support.

I dont see it being an issue.

On the trail guys air down to the single digits without any problems. Obviously beadlocks are recommended when your running them that low. Without beadlock I have ran my tires at 15 psi while offroading.

Thanks guys. I will give 45 a try. It is still lower than what Discount sent me off with albeit just a hair higher than what the dealer did.
Appreciate you guys.

Exact tire pressure to run is a combination of tire construction, rim width chosen and vehicle weight. You have to figure out what is the right pressure for your tire/vehicle/rim combo.

Put about 1/2" of flour on the road the width of a tire. Drive through it. Look at the pattern made in the flour. If the tread digs in deeper in the middle, then your tire pressure is too high. If the tread digs in deeper on the outsides, then your tire pressure is too low. Play with your pressure until the depth in the flour made by the lugs is the same across the entire tire. My guess on your vehicle you'll be at around 30+ psi when you get it right.

It doesn't hurt to do this test front and rear and set pressures accordingly...different front and rear. After all, the front of your vehicle weighs more than the rear and may require slighly high pressure to get proper tread wear.

Too high of pressure and you'll burn your tires up faster and have a rough ride. Too low of pressure and you'll get worse gas mileage and generate excess heat in the tire (what lead to the Ford and Firestone Wilderness AT lawsuits and tire failures).

For the offroad comments, I run my tires at 8-10psi when offroad (38x15.50-16 tires on 16x12 wheels). Haven't lost a bead yet.

Some people aren't sure where to set their tire pressures. The one thing that is certain is that the maximum inflation pressure on the sidewall is not the right one to use.

Good info from everyone. Thanks guys. Going by that chart, I may try their formula. That would be 48psi in the front and 46 in the rear.

OR---I could just put them all at 45 like I said earlier, lol.
