Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.
A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]
The temperatures are inching upward, the days are getting longer and the first buds are starting to appear on the trees. Spring is on its way, and soon it’s going to be time to do a little preventive maintenance on your ride. No need to dread it -- it’s all pretty routine stuff!
- Air filter - If you haven’t changed your air filter since last year (or can’t remember when you changed it at all), it might be time. It’s an easy and cheap fix, and it pays off in your vehicle’s performance and fuel economy.
- Cabin filter - Older vehicles often don’t have a cabin filter, but it can make a lot of difference in how pleasant your vehicle is to drive. Stale, smelly air? Change it!
- Wipers -- Get a good look at them. Are they showing signs ...[more]
