proper tire pressure

Keeping your tires at the right pressure is one of those simple things that makes a huge difference. It improves your gas mileage, helps your tires last longer, and gives you better control on the road, especially in wet conditions. I always check mine when I fill up, using a cheap gauge, and it only takes a minute. It's worth doing, even if it's not the most exciting task.
