i have some pro comp xtreme all terrain 325/60r18 on eagle alloys 102 18x9.5......what tire pressure is the best bet???? thanks guy

 

40psi would be a good starting point.

 

Thanks wandell ill set it too that...but how often should i check up on them to make sure they are properly enflated??

 

I try to check mine every oil change while Im waiting for the oil to change...the tire pressure can have a pretty big impact on gas mileage. Once my tire pressure got about 10 PSI below normal on one front tire and my MPG dropped a good bit.

At least try to check it every other oil change (thats when I try to rotate my tires as well).

 

I just went and checked mine for the first oil change a few days ago and they all ranged between 29-33 PSI, needless to say I went to air up right after that and now all are sitting between 40-45 PSI.

 

Seems a bit scarce on the tire checks to me, unless you change your oil monthly. I check mine tires at least once a month. If you developed a tire leak soon after changing oil, you wouldn't want to wait until your next oil change (3000 to 5000 miles?) to discover it, would you?

 

If those tires are p series tires 40-45 is way too high. What is the max pressure on the side of the tire. If 50, it is probably load range C and 40 would be about right.

 

35to 40

Well since you started this. have a question on tire pressure. I just bought a new 2006 F150 Super cab. I now have 35" BFG M/T'S. on the stock 18" chrome rims. what tire pressure do you think I should run. I have it set at 38 right now, But I think that is a little high. What do you all think??

here is my gallery

38 would be just about right. Those are max 50 psi load range D tires. Recommended tire pressure for my LR C with a max of 50 psi is 40.

 

thanks bud. I also added my gallery so you can see the truck if you want to check it out.
