Spare Low Pressure

So this morning on they way to work the Spare Low Pressure light comes on. It cold here in Chicago so I have had to add air to the front right in the last month but how am i going to get air in the spare?

you lower it and then you can add air to it.

You can also crawl under on your back and reach up to put air in the spare. I suggest when you have the tires rotated you have them inflate the spare also at least up to 35 maybe 37. Easy for them when its on a lift. john

I just had the same problem - they actually had to reconfigure the gage and sensor. The spare is really not in an easy location. especially if you live where salt/sand is used to treat snow/ice.

mine was a sensor problem. The pressure was fine. since it was in for the brake recall I had them deal with it.

I bought me a mini air pump, jumped underneath and aired it up. It's tight under there because the stem is on the top side, but I got it. Also had to air up all four tires due to temp dropping. I bought my own pump because everytime I go to put air in my tires, I end up having to drive to about 3 or 4 gas stations before I find a pump that actually works.

I scratch the belly of my Commander and she rolls over on her back so I have access to the spare to air it up.

This drives me nuts. I have had my 06 for two years, and I have to add air to the tires every time the temperature drops, then usually another 1-2 times during the winter months. I assume this is normal, but I've never had a car with pressure sensors so I have no point of reference. The warnings come on when the pressure gets to around 30-31 psi and I have to add to get it up to 35. I've had to do the spare 4 times in two years, which seems excessive and is a real pain in the *** because of the location of the stem on top of the spare.

This is perfectly normal. You're just not accustom to having TPMS. If you have friends/family or other vehicles, this will hold true as well. For every possibly 8-12 degree drop in temperature, air compresses in, thus your PSI drops as well. A good practice is to add about 2-3 PSI more per tire, when the tires are cold, and your not freezing your butt off too much outside, during the day. This way, when the weather gets colder overnight, the 2-3 PSI you added will eventually level to the manufacturer's setting (generally 35 PSI, which is what my XK requires). As it gets warmer via by season, then you'd just have to leak a few PSI out. In regards to the spare, the tire does not do any pressure changes, so with temperature changes, it'll also go down and down.

The best solution is shoot your tires up with nitrogen. Nitrogen does not change its state per temperature changes. So regardless, your tire pressure will be the same regardless, unless you have a puncture or leak on the tire.

XKJEEP06 is correct, for every 12F decrease in temperature your pressure will drop by 1psi. Inflating your tires to 35-36psi at 70F will typically keep the TPMS in check unless you have extreme cold temperatures (under 10F).

I found that by setting the tires to 36PSI at 70F at a 1100ft elevation, I could travel to 19F at a 7000ft elevation without tripping the TPMS.

Also, feel free to add a few more pounds to the spare. If you ever need to use it you can easily let air out to even it out.
