21 TRD Pro

I’m running Nitto Ridge Grapplers 275/65R18 what is the psi they should be at? Thanks for the feed back.

 

Do a chalk test

 

I was debating on doing it but thought I would ask because I know a lot of people have probably done it already. So I was just trying to get some input.

 

Need more info if you want us to do the work for you...

What load range are the tires??

What is the weight of the vehicle in 'normal' configuration (people, dogs, other payload in the cab and bed, etc...)???

 

Oh yeah forgot to add that, they are the 275/65R18 116T. Normal use some payload and some hauling not close to max just normal truck usage. 21 TRD pro Crewmax normal bed length and just my wife, my small dog and I daily for the most part.

 

This is a great tool for getting air pressure in the ballpark when changing from stock size or load rating tires
