I just put E rated tires on my 2019 Titan Pro 4x. Looking for any advice (based on actual experience) on best cold pressure to run them at. Max pressure is 80 psi. The shop that mounted them set them at 35 psi (what???). I have seen posts of some running them around 38-40, but the suggested pressure with the factory setup is 44 psi. I now have them at 50 psi just to see how that does. Interested in your experience if you have E rated tires. Thank you for any help you can give.
