The P tires called for 35. When I switched to LT I still used 35. I actually aired up for towing but eventually concluded that the LTs did just fine and rode and wore well at 35.
Thanks for this info. Based in generic load index tables, 35PSI would be fine for regular daily driving for me too. It would even be fine to support the actual weight put on the rear axle when towing my specific travel trailer. However, I would need 45PSI to obtain the max rear gross axel weight rating though if I was towing something heavier.
I'm curious but what psi were you using in those P tires.
P metric tires max capacity comes at 35 psi even thought the sidewall may say 44 psi.
Bumping them on up to 44 psi stiffens the sidewalls for hauling or towing conditions.
If you notice the P metric sticker pressure is at 35 psi for a specific load. The same size LT will need another 15 psi or so for it to meet the same load.
However your hard part is finding a psi compromise for handling/ride/less rolling resistance/etc from those heavy E tires.
