What P.S.I. do you run in your tires?

At the dragstrip 65 to 70psi in front tires,18 to 22psi in rear drag radials depending on traction,what else do you want to know,lol.
You should qualify your question a bit better,what are you looking for "best ride" , "best mpg" ,"best tire life" they all dictate a differant pressure depending on what you want out of your tires
Chalk test is a myth. Just got done explaing this in another thread on herechalk test the tire for best wear, obviously higher tire pressure if hauling/towing.
Don't know what to tell you, it works for me for the driving that I do.Chalk test is a myth. Just got done explaing this in another thread on here

Just saying, it's not avalid test, laws of physics can't be changed. Measurement on a tire at almot null speed vs that tire at highway speed, the contact area is vastly different.Don't know what to tell you, it works for me for the driving that I do.

Like I said, for the driving I do it works. Now if I was doing a lot of hiway driving I would have different psi's or if pulling / hauling stuff I'd probably go with another psi. Absolutely physics is the big factor. I don't think there is one right answer for what psi to run. Maybe I should have said that at the beginning [emoji848].Just saying, it's not avalid test, laws of physics can't be changed.

I agree chalk test shows 15 psi to 50 psi all being fine on my jeep. Never worked for me. I use the 10% rule and that has always given me even tire wear.Just saying, it's not avalid test, laws of physics can't be changed.

This is goodThere is one fairly simple way, it is getting a bit more difficult now days.
Go to your tire manufactures web site and find or contact them for the pressure to load data for your tire.
They will have a chart for your tire and the ideal pressure for the weight it is carrying.
With that chart and a scale reading of your trucks axle weight as you are going to use it you can find the tire pressure recommended by the tire manufacture.
Those data charts used to be published and available at the dealers now they seem to hide them at times.
here is a sample;
