Should Tires Always be Set to PSI Rating on Tire Sidewall and Where Should TPMS Alerts be Set

Question:

I just bought a TPMS for our Cherokee Grey Wolf 26dbh. on the side of my tire it says 65 psi cold max. Does this mean i should always have my tire at 65 psi or is that mean that is the max? Should i set my TPMS to warn me if it s below 65? just confused lol. thanks!

Yes, you want your tires, like the Kenda # AM32418DX, to be at that 65 psi they are cold (or have been sitting for quite a while like overnight). When you start heading out the tires will naturally heat up and expand due to the friction with the road so it's usually a good thing to set the alert for the tires about 20 psi higher than the cold psi rating.

It's also a great idea to set your TPMS to warn you when the psi rating falls below that 65 rating. I recommend shooting for 5 - 10 psi below so you'll be well aware before the tire is flat. When the temperature changes this will affect the psi rating as well which is why it's good to have these parameters.
