On my old silverado I had falken 265/75/16's that I ran at 40psi. Found that to be the happy spot for wear & handling, etc. On the new rig there are 275/65/18's which are currently sitting at 38 psi, which has a lil bulge look going so time to add. Was just curious as to what some of you with a similar tire size run or recommend.

Thanks.

Sounds like you have stock tires. The door jam will tell you the exact number. I think it was 35-36psi.

Whatever's on the door jam... 36 I think.

Door Jam Sticker - 35 psi for my truck.

I always see 36 on my in-dash computer screen, but I just remembered that hot air was increasing the PSI! 35PSI cold!

Right. Never fill tires based on look.

Was the falken An A/T ?
They usually have stiffer sidewalls.
You should be fine as long as you don't exceed the maximum pressure stated on the tire itself.

Yes the falkens were a/t's. There are goodyear wranglers series on this rig, ats's if I recall correctly. Sidewall says max pressure is 65psi. Recommended doesn't always mean required. Every tire & driver are different.

35 PSI seems to be the sweet spot for wear and ride quality on my truck. I have 15k miles on my BFG's and they look brand new still. I also rotate them every 5k miles when I change my oil. I'm sure that helps.

I'm running 38-40 psi. in 275/70/18s BFGs
35psi. felt a little soft..... but I drove a SD F-250 13 yrs. prior.....
So the whole F-150 platform felt really soft and squishy to me already.
Thought I read on the forum that people were recommending 50psi in the BFGs because of the E rating, are your 17s D rated?
