im going to be moving down to tx next week and am wondering what my tire pressure should be in my tires. the tires i am using are 275/65/18 goodyear wrangler duratrax load range e. the side wall says 80PSI max but the door says 35PSI. So i dont know if i should go with what the truck says or something different. I will be towing a 6x12 uhaul trailer but it shouldn't be super heavy because i dont have much to take with me. any suggestions on what i should be running would be appreciated.

 

Go by the door. Even better, check the print of your tire and adjust . Most likely towing you want a bit more in the rear.

 

print of my tire?

 

I run 60 all around in my duratracs. I feel like the duratracs feel too mushy with any less

 

i think im running 45-50 all around (its either one or the other, just dont remember which) but am just worried about chewing them up on the 1500 mile trip.

 

Run your pressure up to around 65psi. Dont go by what the door says. 35 psi is way too low for an E rated tire.
Actually E rated tires are made to run at 80 psi.
In my old truck (GMC 2500 Duramax) I ran my E rated tires at 80 psi when hauling or towing then backed them down to 65 psi for everyday use.

 

50 PSI summer/ 40 PSI winter

 

The sticker on the door jamb always refers to tire pressure recomendations for tires that are stock. If you have replaced the rims with larger diameter ones, or have replaced the tires with a slighly larger width or height, then the door sticker recommendations are no longer valid. Go to a tire store (if you bought them, go to that store) and get their recommendations and write it down and use that.

 

80 psi holy crap id be paranoid the tires gonna explode in my face airing a tire up to that much.
