Tires are load range E and are at best load carrying capacity at 80 psi. However, the truck is only 7000 lbs (give or take - you need to fill in your signature so people will know what year and type of truck you have). 80 psi empty is way too much inflation and will "crown" your tires very quickly. Early on, many dealers were setting the fronts at 45 psi for "drive comfort" that ATE THEM UP with the weight of the diesel engine. After 119,000 miles and three sets of tires on my shortbed extended cab 2500, I run 55 front and 45 rear unloaded. I air the rears up according to load and take them back down when empty.

First, hi and welcome.
Second, hide your wallet- we'll get you in trouble here.
Third, fill out your sig. so we know what truck we are talking about.

Good rule of thumb, max psi (80) while towing, and 50 - 65 cruising town for a softer ride. I tow off and on alot, so I just leave mine at max pressure the ride is fine.

Just go to 'user CP' at the top of the page, then click on 'edit signiture'.

55 is a good starting point, I usually set customers HD's at 55 for a good allaround feel.

There is a file size limit (can't remember the exact limit wanna say 5mb though
) AND a pixel size limit (think it 800x600).

Need to resize your pics to the required limits. It should tell you what is too big.


IF you don't have a special picture editing software, just use MS Paint to shrink the picture.

If you look at the tag on the door jam on the driver side you will find that it gives you the psi.'s for the 245/75r 16 tires that came with your truck. What I did was check the temp. of the tires on the sides and middle of the tires after driving and add or remove air till the temp was as close as the same then let them cool and check the psi. than drive it agian and check the temp. and if the same that is how much air you need in your tires to get the best traction and ware from your tires.
