Truck Guru's
Any truck/auto experts out there? I bought a new Chevy Silverado Black Widow a few months ago. Has all the upgrades and 35 tires.
Got a screw in one tire today and brought it back to dealer to fix.
After fixing, they noted my tires had standard 32 ish psi.
They said, "these tires need 70 psi" and put that in them.
I asked, Black Widow built this truck, and delivered with 32 psi, wouldn't they have known that?
They said not sure, but they need 70 psi.
I am obviously not an auto expert - does this sound right?
I'm relying on my gun expert friends for this one - lol
Thanks!"Tastefully Pimptastic"

I don't know what a Black Widow truck is but there should be a sticker on the door jamb with recommended tire pressures.

Re: Truck Guru's
they are probably delivered with the 32 psi for comfort. however i would go by the door jamb psi. 70 psi is more then what my f250 calls for.

32 is too low for any vehicle on PA roads short of Hoosier or Mickey Thompson racing slicks.
E rated or heavy load truck tires cat be set up to 90 psi but they don't have to be. Mostly for trailer towing or hauling heavy loads.
Play around with different pressures and see what gives you the best ride. I'd try around 45-50 and go from there. The more PSI the harsher it will be.Accuse your enemy of what you are doing as you are doing it to create confusion -Karl Marx

^ This.
When the weather is better do a "chalk test". Pick up a small box of sidewalk chalk
and use one of them to make a wide chalk mark a couple feet in front of each tire.
Then drive the truck over the chalk and try to get the chalk on the tire so that you can
see where the tire picked up the chalk, it should be on the tread from edge to edge.
Adjust pressure accordingly.
The max pressure on the sidewall of the tire is based on the max load range for the tire,
but the PSI seen on the door jamb sticker is for your vehicle's weight and GVWR.While many claim to support the right, precious few support the practice.

Re: Truck Guru's
Should be right on the tire what pressure needed.
Today was a good day!

Re: Truck Guru's
I run 65psi in my truck. It's higher but the tires can handle it, and i get more mpg. 32 is to low any way you cut it, especially for a truck.
