Hmmm, sometimes I think I force the titles for these posts. Anywho, the Alliance of Automobile Manufacturers is promoting a new safety feature for all new cars in 2008. It’s TPMS, tire pressure monitoring system – the name explains it all. When your tires are under-inflated a light will come on your dashboard and tells you to get more air in them.
Why the heck should you care about tire pressure? Well for every 3psi drop in tire pressure you can expect a 1% decrease in fuel efficiency. If an average Nova Scotian was low 2psi in each of their four tires, they would be using an extra 85L of gas a year, that’s about $100 and .2 tonnes of CO2. Even more staggering is that a recent pan-American survey by CarCare found that 70% of cars had at least 1 tire improperly inflated. If you don’t care about saving fuel, at least this’ll help you save your tires. Under-inflated tires will lose their tread about 15,000 km sooner and this system will also alert you as soon as your tire flat. Not a bad idea, but tire pressure gauges work pretty efficiently as well.
