i have done a search on here and on a couple search engines and nobody seems to have a definate answer as to what tire pressures work best...they get too technical about loads and ambient temps. also it seems to be about 50/50 to inflate to what the tire says vs. what the door sticker says...i know different sizes require different pressures so i cant go by what the door says...my sticker says to set215/75-15's at 35psibut i have 31x10.5x15. the tire says max load at 50psi which i think is way too high for normal driving so i put them at 40psi...ill see how that works i guess

i would like to know what you all set your tires at with just average daily driving for best wear and mileage, not hauling anything or towing anything.

 

mine say 35 max i inflate to about 33. mine lose pressure quick tho .. seems i have to check them every month to keep them steady.

 

Your proper pressure for 31x10.50s is 35 psi in front tires and 41 psi in the rear tires. I also have a Dakota that came stock with 31s while the door sticker does say 215/75R15. And, my information comes from a Michelin MAST Fitment Guide, which is basically the bible for tires.

 

I keep mine at 36 psi, but I haul with mine. Our winters can be brutal, with as much ice as snow, so I may drop them down to 30 psi maxwhen the weather gets bad for traction, although I've been told that will not help your traction ?

 

i was keepin mine all at 40 over my christmas break and was getting some good gas mileage.

 

i keep them at what the tires say
50 in the rear 31x10.5, 40 in the front 30x9.5
no problems, good mileage, tires still look new after a year and 15,000 miles

 

that is normal to check them about every month...tires lose 1-2 lbs a month on average

 

Is there a web-site you can direct us to or somewhere we can buy this Michelin tire guide?

 

batman13 and dragon8master----why should the rear tires have more pressure than the fronts? what does that do?

 

idk my door says 30 something but i run a little over 35 and it seems to be doing me good
