All 2008 cars will be equipped with TPMS (a Tire Pressure Management System) to let you know when you need to add air to your tires. Don’t rely on these systems to keep your tires at proper inflation, they won’t. These systems don’t warn you until your tire has lost 25% of its pressure, the point at which danger may loom. Besides, there is a huge correlation between tire pressure and gas mileage so driving around 15% low is environmentally irresponsible and will cost you money in the long run. Tires will lose pressure over time regardless of conditions, so checking your tire pressure at least once a month should be on your don’t-screw-it-up checklist. The temperature has finally dropped in any part of the country that actually gets a winter. This means your tire pressure has taken the plunge along with it. Did you know that for every 10 degrees the temperature drops, your tires lose 1-2 psi of air pressure? That’s enough to give your gas mileage a punch in the stomach, for sure, not to mention the safety concerns that arise from low tire pressure. Don’t delay, check your pressure today!
