What is the correct tire inflation size for a Hummer H2 with stock tires?
I've heard of people having their tires between 41-45, Is that correct?

 

Look at the sticker on the edge of the drivers door. It's usually 37PSI. I run mine at 40PSI and pick up 1MPG. I run mostly highway. Not sure how the tires will wear or how much traction you wll lose if you go over 40

 

Hi,

Look on you tire by the rim, thats where the (cold) tire pressues are listed,you also have the DOT number and when the tire (date) was made..........

When i buy new BFG tires from tire kingtom, i check made dates for fresh made tires, they last longer and are smoother than old tires left in a tire rack for a couple of years..........

Each tire has there own pressures due to size and ply rating............

but if your going mudding/rock cralwing you can lower you pressure for better tracking and less side wall damage..........

Have a great day...................Rick H2/H3
