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 that 60 to 80 percent of the vehicles on the road are rolling on tires that are low on air.The tire pressure monitoring systems on newer cars are all well and good, but what can be done to ... read more

Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road.As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair work starts: Does your shop work on any kind of vehicle? Of course, most shops can service a product from GM, Ford, Chrysler, Nissan, Toyota and the other leading makes. Some makes, however, require a lot more training and experience, or even factory certifications. Vehicles from Mercedes-Benz, Volvo, BMW and certain other makes often require specialized tools and training; that’s why many towns have repair shops that are for specific makes of vehicles. What kind of equipment does your ... read more
