A dumb question

[thecraft]

How much air pressure should I have in my tires? Heh heh...

 

Hear me out guys. I know there is supposed to be a sticker with this information on the driver-side door jamb, but my truck doesn't have that sticker anymore. A few years ago (when the previous owner still had the truck), someone driving a van ran a red light and sideswiped the truck. They ended up replacing all of the body panels on the left but not that sticker. I can't find any info. in the glove box or manual, can anyone help me out? My truck is described in my sig, if you need any RPO codes, just let me know.

 

Alrighty then, so here's the story. When I returned from hunting this morning, I noticed my right rear tire was bulging "more than normal." When I kicked it, it wiggled like Jello! I grabbed my tire gauge and checked it... 20psi! That can't be right... so I tried using my dad's tire gauge, sure enough, 20psi. I checked the other tires while I was at it. I got 30psi in the left rear, and about 27psi in the front tires. Since I didn't know what my tire pressure should be, I just added 10psi to the right rear tire and left the rest alone. I still believe that 30psi seems a little low... am I right?

 

Thanks... stop yer laughin'

The sticker on the door will only be as accurate as the tires on the truck. ;)

30psi is a little low.

What type of tires do you have on the truck? That'll make a difference. And the tire will specific the MAX tire pressure.

I usually run 32-35 in all of em. Makes the ride a little smoother, but some will say it lowers your gas mileage.

 

By the way, I've got the 4wd version of your truck, so it'll be the same.

I run 32 all the way around for ride quality

Okay, thanks for your help guys. I will bump them up to at least 32psi tomorrow when I get the chance.

 

@ pwall: They are Highway Terrain All-Seasons.

I have Toyo MT's which are 10 ply's and I only run 32psi in them and they can handle upwards to 50psi depending on your load ratings. So it totally depends on the brand and size and ply of your tires dude.

It does depend on the tire construction and brand/size. For example, the original tires on my old Jimmy actually stated that they couldn't handle more than 35 PSI but they were load range C...The tires I put on it could handle up to 50 PSI and were also load range C...However, I've always found that experimentation is about the best thing you can do to get even tire wear and the best gas mileage. I usually start off at about 35 PSI and go up or down from there.

35 is what they should be at, but depending on what tires youre running , it could be 40+. Our 2500hd was running 8 ply tires when we got it @ 80 PSI
