Low Tire Pressure Light

Update (from an earlier post): the last time I went up to the mountains to snowboard the TPMS light came on after my 4R was parked for 7hrs. After about 30mins of driving, it went away. I initally thought it was the 4 tires and not the spare because I usually keep the spare @ 40+psi. It's been awhile since I've last check the spare (approx 10 months or so) it must've lost a decent amount of pressure to trigger the light when it got cold.
Anyways, what I find interesting is that about a month ago, I started hearing a clunk/rattle coming from the rear of my 4R whenever I went over speed bumps or make sharp turns. I thought it might've been from either the snowboard carrier or my roof cargo rack, but sure enough, it was the spare tire shifting around. It lost enough pressure that it was no longer secured snugly and had enough play to swing around a wee bit. Interesting enough though is that my TPMS light hasn't come on at all since that skiing trip. I haven't had any time lately to bust out my 15gal air compressor, but I did tighten the spare tire carrier cable a little bit more. Just curious if anyone else had their spare tire come a bit loose due to low pressure.

You can put up to the maximum on the tire sidewall. It might be around 40psi or so. The ride might be firmer and your tires might start wearing out the center thread. I would recommend 35psi. Also when you're adding air, do it when the tires are cold. If you've driven to a gas station or some place to get air the pressure can be off. One way to get around that is take the pressure reading when cold and subtract the reading from where you want the pressure to be. Once you get to the gas station, take the pressure reading again and add the difference to reading for your final pressure.

Fly,
I have been running 40 psi in my Cross Terrains for over 50,000 miles. I measure tread wear with a depth guage and the wear is surprisingly even across the tread (and overall very low). I still have plenty of tread on the original tires.
However, this tire is rated for 35 psi so please don't take this as a recommendation but rather as relating my own positive experience.
