Tow Vehicle Tire Pressure
Do others increase / decrease the tire pressure in their tow vehicle when they are pulling the trailer? My truck specs say 35 psi for all 4 tires, but nothing about adjusting when towing. I'm thin...

To all, Thanks for the responses. I've actually been away traveling and working so have not been able to check back in. Anyway, yes my truck is is GMC Sierra 1/2 ton. The door sticker refers to a P rated tire. I did put a 10 ply tire on (I think that is a E rated tire). The door spec is 35 pounds. The tire says 40 up to 80 max. If I run over 40 without towing it is very rough and shaky. Maybe another issue, but many parts are new except for shocks and really can't believe that will cause that issue. Anyway, thanks for the input and I think this did spark some other questions and answers.
