I heard something that you need D or E rated tires if you are going to tow. But it looks like my tires can handle 2535 lbs each, so shouldnt i be fine?
Pump those rear tires to their max sidewall pressures which can be 44 psi or even 51 psi on some P tires.
Sway issues can start with using the door sticker 35 psi. The sidewalls are to soft for towing/hauling a load duties.
I pull a 10k trailers with the wifes 1500 chevy rolling on P265/70-17" tires. Their max is 44 psi. I don't mess with the front tires psi as their load never changes.
Years back or passenger tires pressure was limited at 32 psi. Radial tires came out with 35 psi....and now were up to 44-51 psi for a much stiffer sidewall.
I'm not a fan of a LT D or E tire on a 1/2 ton truck. BTDT and always came back to a P tire.
