So I've been looking for solid information on how much pressure to put in tires, when moving away from stock tire size or type ("P" vs LT, different load range, etc).

I never found anything to-the-point, except I remember someone talking about using GVWR and max tire load to calculate pressure. And I can't even find that post anymore.

 

 

Anyhow, I decided to make this from scratch:

It doesn't mean that it's exactly the tire pressure you should use, but I guess it's a good start.

 

I hope it might be useful. Cheers!
