I noticed that on my door the tire pressure says 50/60 f/r psi for light load... but when i look at the tire it says 35psi max for light load. which should I go by? the front tires just look too low with 35 psi

 

What brand/size/rating are your tires?

If they are factory, I'd go by the door sticker. I don't believe the tire manufacturer would consider the 1500 pounds of the cummins/tranny to be a light load...

 

35 psi MAX ??

For a TRUCK tire ??

I'm running 70 psi in mine. Re-read the tire and make sure you weren't reading the MINIMUM.

I really wish they'd make that print a little bigger on tires. It's almost like you need a Harry Potter secret decoder ring just to read the print on tires.

 

It is possable that if he bought it used or changed the tires someone could of put/sold P/XL rated tires and put on it if it does say 35 psi max.on the side wall.

 

I'd go between the two. I know the tires can carry more pressure than what is printed in max... but that is a HUGE discrepency

 

if those tires are really only 35 psi max than they have no business on a truck!

You want tires that are load range "E", with a typical maximum tire pressure of 80 PSI and rated for 2,680 Lbs. Single or 2,470 Lbs. Dual. If your tires are showing 35 PSI Max, then they are passenger car tires, with less than 1/2 of the load rating you need for your truck.

 

MAKE SURE THE TIRES ARE RATED FOR YOUR TRUCK THEN FOLLOW THE DOOR STICKER. ON THE TIRES IT TO FOLLOW THE MANUFACTURERS TIRE PRESSURE RECOMENDATIIONS.IF THE TIRES ARE ONLY RATED FOR 35 POUNDS OF AIR THE ARE CAR TIRES, BE CAREFULL
