HI,

I have a general knowledge question for ya.

You know how on the inside of the driver side door it says what pressure (psi) to inflate the tire to.
Well stocks on this blazer are 16's so that pressure is for the 16's.

But I now put 20's on my blazer. How do i know what psi to inflate my tires to?

Thanks a bunch

 

Look on your new tires. They will have recomended tire psi stamped on them. you will have to git up close and personal with your tire. The writing is usually fairly small. The little writing will inform you of max load per tire, rated and recomended psi, plys and stuff.
