Tire Pressure?

All my past vehicles have had stock tires, or the equivalent size, so I've always used the sticker inside the driver's door to determine tire pressure.

The 2022 I just bought has larger tires than what's listed on the door sticker. How do you go about determining the proper tire pressure? Is there a better way to calculate it, other than the old chalk test?

It's mostly for city use, with some occasional fun up the dirt roads.

 

Size of new tires?

Inflate until one explodes. Replace tire. Run less than that.

 

For a P/Euro-metric; until it has 2,149 lbs of inflated load capacity.
For a LT: until it has 1,954 lbs.
Use a chart...

 

Deflate until one unseats its bead. Seat bead. Run more than that.

 

I run 34 to 35 PSI to start. Then monitor thread wear and adjust PSI accordingly if needed.

 

Check inside door post and you will find the PSI that is for stock tires unless you have bigger then I am not sure, I guess you could also have to look on the tire itself. just saying

 

Use this calculator. It will give you the new equivalent pressure.

 

We Need to know size of tire and load rating.

 

Chalk test is best indicator of what pressures your truck wants

 

Do you do that with the tires cold or at operating temperature?

 

OP said the tires are larger than stock. Tires themselves don't list the recommended PSI, only the Max PSI (which is not what you should be running). The tire doesn't know if it is on a Tacoma or 4Runner, for example. Both have different weight properties and may require different things.

 

Perfect, thanks!

 

I’ve always done it after a 5 mile or so drive.
