I have a 1998 k1500 extended cabwith 245/75/16 tires, what tire pressure should I be running in my tires? The sticker that should be inside the door is gone.

 

Look on the tire

 

should be in the 35-40 range, but it does depend on the tire.

 

I can't find it on the tire, it currently is p rated tires (which are going off next fall) does that help with the tire pressure recomendations? Thanks for the help so far!

 

Some where on the tire should say 40psi cold or or something like that. Mine says like 65 psi maxwhen cold. So look at all four tires it should be on there.

 

Woah! That is the MAX not the running pressure! 65 psi MAX COLD pressure is the highest safe pressure that tire can run. 35 psi should be plenty on a 1/2 ton with C load range or lower (P rated), 40-45 on a 3/4 with D load range or lower, and 45-65 on a 1 ton with E load range or lower. What I do is balance it out better for winter where I am not hauling anything. So I actually run 36 psi up front and 34 in the rear to keep the front off the sidewalls and the rear from bouncing around.

 

No matter what anyone says look at the tire, it tells you what the max pressure is of that tire... keep it under the max but not under by more than 10 psi

 

damn looks like i may to need to inflate some more.

 

The "P" you refer to indicates that it is a Passenger tire,as opposed to a "LT" light truck tire. "P" tires have lighter construction and fewer sidewall belts, and are intended to run at lower pressure as well as handle less weightthan a "LT". My 2002 Silverado 1500 Ext Cab Z71 came from the factory with P265/75/16 tires and the door tag confirms that info and all 4 should be set to 35PSI COLD, again COLD,Stone Cold,not driven as much as 2 blocks to the filling station. Just a very short distance raises the temp of the tire and can change the pressure considerably. Both of my vehicles will change 3-4 pounds in the distance from home to the gas station(approx 1/4 mile) and my Truck with 400-500lbs in the bed going 20 minutes on the freeway changed 8psi last fall. The sidewall pressure tag is the MAX reccomended COLD PSI. All that being said I regularly 38PSI in my SIlverado "P" tires year round, rides alittle harder in the winter,but tires wear more evenly than the same brand/model did at 35PSI ans the Gas Mileage is Slightly better. As a side note a few of my friends have been running "C" load "LT" tires on the 1500 Chevys( at 50-55PSI)and although they ride TOO firm for me, they have consistantly been gettingMPG and the tires are lasting between 80-120K. One buddy had his rims/tires stolen off his brand new 2004 1500 before he even took delivery and had the dealer put Michelin "LT"'s on it, now has128K on it, the tires passed inspection,but weren't really up to this Notheast winter.

 

Jason248:Most max psi's are between 60-80psi. You mean to tell me you recommend 50-70psi normally??? ROFL!
