I cannot find the pressure recommendation for my 2000 Chevy Silverado 1/2 ton Pickup anywhere. The owners manual stats "see door jamb", but the door jamb has no labeling at all. I cannot find the spec on line, either. Anyone know for sure without guessing? Thanks.
 
Good thought, but unfortunately, no. This has befuddled me. The door jamb shows no evidence of a label that possibly fell off.
 
First, the vehicle tire placard might be on the door itself.

Second, there are so many different configurations for "2000 Chevy Silverado 1/2 ton Pickup" that is almost impossible to figure out what you have and what the placard would have said.

So spend some time looking for the placard. It is the best source of information.

But assuming that it has fallen off:

1) Is the vehicle a 4X2 or a 4X4?

2) Regular Cab or Extended Cab?

3) Long Box or Short Box?

4) 1500 or 2500 or 3500?

Lastly, I suspect the vehicle placard said P235/75R16 106S. It is NOT an "LT", it is a "P". LT tires will be dual labeled like this: 110/106Q (with a couple of exceptions!)

::pssst! LT235/75R16's don't exist!::

And since it is a "P", that means the vehicle tire placard will say to use 35 psi (according to Tire Guides).
 
I too have seen the recomended PSI listed in the glove compartment of the center arm rest compartment when you can't find the information on the door jamb.
 
Like CapriRacer mentioned, give us all the info he asked for and I will drive down to my shop and get the Tire Guide out and let you know, even though I am closed today and tomorrow. Whatever you need man, just let me know the following info.

It's just not there, on door or jamb, or glovebox or owners manual. No evidence of an area where it fell off.


1) Is the vehicle a 4X2 or a 4X4? -------- 2WD

2) Regular Cab or Extended Cab? ---------- Extended cab.

3) Long Box or Short Box? --------Short bed.

4) 1500 or 2500 or 3500? -------- 1500

It must be a "P". I assumed it was a LT because GY Wranglers are percieved to be for trucks.


Thanks to all of you for the replies. I normally run 36-38 PSI, but the guy at the used tire shop told me my broken belt was caused by too much pressure. I disagree, I think 38 PSI is OK, but thats why I sought out the official recommendation.

I think 38 psi is fine. My tire placard lists 35psi for my LT265/70R17's and I run them at 40.

According to Tire Guides, this is incorrect. They list 35 psi front and rear.

mjoekingz28: What is the source of your info?
 
In my experience, it's highly likely that your truck requires 35psi (COLD psi) all around. 36-38 psi is not unreasonable at all, especially when warm. Furthermore, tire belt failure can be attributed to a wide range of variables and probably not the 1 or 3 psi.

I apologize if Im wrong. I 'thought' I remembered it stated on the placard from airing up the tires in my grandpa's circa 2000 model 2wd Silverado 5.3.

I'll have to go over there and find out for sure now!
 
Old rule of thumb is to add more air if you can't jam a business card 1/2" under the edge tread, and drop pressure if you can.

As I said, old and rule of thumb.
 
Best way to optimize your tire pressure: Per a Porsche factory racing team mechanic years back...

Measure cold.

Drive.

Measure hot.

You need to see a 2 psi difference after driving. If it's greater than 2, ADD pressure. If it's less, reduce.

This has put most of the passenger and light suv vehicles I've known from 30-34 cold. It puts my grand cherokee right with the door placard (35??? IIRC???)

My Saturn manual states to add 4psi when hot....when checking the pressures.
