Correct PSI

[Guest jerrynmn1]

I have a 1997 Pathfinder SE with specs for P265/R70/15 tires I just bought 4 Pirelli scorpion tires in that size. The Pathfinder tire label in the glove compartment calls for 26 psi in both front and rear tires but the tire dealer I got the tires from said to put in 32 psi- Who is right as I have always been taught that the tire label in the vehicle is the only correct psi to use for that size tires for the vehicle and not to use different psi not listed on the label in the vehicle-Opinions????-Thank you- Jerry

I run my ATs at 34-38 PSI. Awsome for fuel economy.

I run 45 PSI on my 02 but I also use LT rated 10 ply tires. I always rely on the tire shop, the sticker is just for the stock tire.

28-30lbs here. BFG AT TA's. I like the cushy ride. (and fewer rattles)

 

Here's the question(s), do you want a softer ride, or are you willing to sacrifice a softer ride for better gas mileage? Do you spend most of your time on road, or off?

 

Lower pressure will have a softer ride and more rolling resistance. Higher pressure will get better gas mileage because of lower rolling resistance. Too low of pressure and the tires will wear on the outside edges. Too high of pressure and the tire will wear in the center.

 

Lower pressure will also give you better traction. When offroad, I run 12-20lbs, depending on conditions. This makes a bigger contact patch and allows your tire to "wrap around" an obstical. Drag racers also run lower pressure to get better grip on the track.

 

The 26lbs Nissan recommends, imho, is just a good place to start. Drive it for a while at 32lbs, then drop to 26lbs. I bet you feel a difference in ride. Then try airing up to 36lbs and see how it feels there. Before you do this I would reccomend you check the pressure range on your tire and not exceed its limits. Experiment.

You just need to find a balance to your liking.

i go with tire manufacturers recommendations although BFG wants upto 50psi in there.. i run around 35psi for regular driving.. offroad: well that depends but 15-35 is the range..

BFG's rating of 50psi on the AT's is for attaining the maximum load of the tires (i.e. when your towing/hauling an extremely heavy load).. not for normal driving
