For those running KO2 265/70/17 C

Been looking around and can't decide on tire pressure.

I do some what heavy hauling once a week (about 20 to 30 cases of waters etc.). I just got C rated Ko2s and the tire shop has set them at 31 all around warmed up. Just wanted some advice from you guys on what tire pressure I should keep the tires at the set 31 from the shop or go up to the 35 to 38ish range I've been seeing around on some threads. Your time is greatly appreciated.

Thanks.

 

just got my 10K service today and they adjusted to 30psi. It was 32psi.

 

Lol my tire shop set them at 40. I immediately lowered it when I got home And now keep mine at 36 psi. I try to leave some squat in them, chalk test checks out as well.

 

I've had mine for about 10k miles so far and have always run them at 32psi. Never had any issues and they ride fine to me. When they warm up they're at around 34-35psi. I've never done the chalk test but they're wearing very well, still looks like brand new tread.

 

You should be at 37 psi, cold.
This gives the factory load capacity; adjusted for size and P-to-LT.
You'd probably be fine at 31 psi if you never hauled any weight.

For your tire size and load rating, it equates to 37lbs/1 psi.

37-31=6psi
6psi x 37lbs x 4 tires is 888lbs of load capacity difference.
30 cases of water is about 900lbs.

 

I run mine at 37.

 

I run 36ish cold. Wearing evenly.

 

My tire shop set mine at 55 psi. Lol

 

I had mine set 37 psi. Runs good and mpg seems the best here for me.

 

I dig the maths, will be going up to 37 psi. Thank you to everyone else as well

 

You can also email or call BFG. They emailed back to me within a couple of days with the correct psi for my 4Runner. I also called them to double check and a nice lady looked it up on their charts and told me the same psi.

You could literally call BFG today and get your psi for your particular truck.

 

They have a habit of not derating when going from P to LT.
