    Temperatures are dropping!

    This weekend is a good time to check your tire pressure and top it up.

    With lower temps you may be a few pounds low- maybe not enough to trip the TPMS (if any) but you can still lose fuel economy before that tire light comes on.

    I'll also suggest basing your tire pressure needs on the roads you drive on rather then what the tire maker's lawyers decide to stamp on all the tires. As in add a couple few pounds of air at a time and then on a rainy day if your tires slip a little accelerating hard away from a stoplight you know to lower tire pressure a little to improve traction. And as always, because the engine is in the front you'll want a couple pounds more in the front than in the rear. In winter for me that works out to about 45psi in front and 43psi in the rears and higher than that in the Summer.

    Saturday bump- all 8 tires in my family fleet needed a few pounds each, how did you do?

    And check tread depth. 3/16 of an inch minimum here in Colorado.

    Also check tire rating. Must have either a M+S symbol or a three-peak-snowflake symbol, or both. (Unless it's an AWD or 4WD, in which case in Colorado you can legally drive around on summer tires, something that I do not agree with).

    Similar here several weeks ago, will need another check soon as temperatures continue to drop.
