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]
In a perfect world, all four tires would wear out at the same time. In the same perfect world, everyone would be able to afford a whole set of tires all at once. Unfortunately, things often just do not work out that way.
Sometimes you may just have to replace tires as you can afford them, one or two at a time, but there are some important things to bear in mind if you have to do that.
If you can only afford to replace one or two tires, it’s essential that you go with tires that are identical (or at least as close as possible) to the car’s remaining tires. That means that internal construction, size, tread pattern and design should be close to the same. Don’t mix winter tires with all-season tires, don’t mix run-flat tires with ...[more]
- Battery: Extreme heat and extreme cold can both stress your car’s battery. At 5 degrees Fahrenheit, a fully-charged battery can only deliver half its rated cranking power; cold temperatures slow down the chemical reaction in the battery that actually provides power. In addition, motor oil thickens and becomes more viscous at cold temperatures, making it harder to turn the engine over. Remember that your battery is only as good as its connections; chec ...[more]
- Everyone tends to think of tires as being round and black…but black is not the natural color of tires. The zinc oxide in early tire tread compounds resulted in a grayish-white color; it wasn’t until years later that carbon black was added to tread formulations. Carbon black enhances wear and durability, and conducts heat away from the tire’s internal structure. Early tires only had carbon black in the tread area, hence the first whitewall tires. Today, whitewalls and white-letter tir ...[more]
We often see customers who are a little overwhelmed by the tire buying process. There are so many types of tires for different vehicles and different driving styles, all at different price points. Here are a few things every driver needs to know about tires:
· A tire is constructed from the inside out, starting at the inner liner. There are 20 to 25 different components in every tire; fabric belts are wrapped around the inner liner, with steel belts, more fabric belts and other materials layered between the tread surface and the inner liner. These layers provide strength, noise suppression and ride quality.
· Newer low-profile tires are popular with many drivers, if only for aesthetic/style reasons. It’s important to know low-prof ...[more]
So your closet has a pair of flip-flops for the summer, a pair of heavy boots for the winter, and a comfortable pair of sneakers for most of the rest of the year. If you live in a climate that doesn’t have harsh winters, you might just be able to wear those sneakers year-round...and all-season tires are the equivalent of your comfortable sneakers.
So what makes all-season tires so special?
Winter tires are excellent for severe conditions like heavy snow and even ice. They feature specially-designed tread patterns and “sipes”, hundreds of tiny slits which offer biting edges for traction in snow. This means shorter stopping distances, better handling and better control in winter weather. Winter tires are not d
esigned for temperatures above 40 degrees Fahrenheit. The do ...[more]
