There are so many tire designs on the road -- all-season, high performance, touring, light truck -- and even within a specific tire design, there may be several choices of tread patterns. What differentiates them, and what are the pros and cons of each tread design?    -- Directional tread has a pattern of grooves and chevron shapes, all pointed in one direction. This design makes it easy to direct water away from the tire's contact patch and prevent hydroplaning in wet weather, and also offers...

The tire is such a commonplace item -- it's on every car, every truck, every bicycle, every aircraft. It's easy to not give the tire a second thought, but like every other technology, the tire has an interesting history of advances and failures.    In the 19th century, carriages and wagons used steel strips for "tires" on their wheels, with the punishing sort of ride that you'd expect. In later years, they were shod with strips of natural rubber, which was an improvement but was still problemat...

Nobody ever looks forward to a flat tire, and nobody ever says "well, that was a really good time" after having one. You can at least minimize the damage to your tire and danger to yourself, though. Flats vs Blowouts If you get a blowout, you'll know about it right away. Sometimes the tire can fail dramatically, with a bang as loud as a shotgun going off. Other times, it might just be a loss of air and a sudden change in your car's handling, followed by vibration, noise and a pull to one side. ...

When it comes to your car, oil isn't the only thing there's a finite supply of. Rubber has its limits too, and it's estimated by 2020, the supply of natural rubber in the world may be outstripped by demand. And of course, tires require a great deal of oil to produce as well. Tire manufacturers are constantly looking for ways to innovate and conserve resources in tire production. Here are some recent advances: Dandelions: Yes, those humble yellow flowers you try to eliminate from your yard. Da...

Tires all look sort of the same…round and black…and people tend to think tires don’t change much over the years. That’s really not true, though – engineers and designers are constantly working on advances in tire designs for more miles, better fuel economy and better performance. Here’s a rundown of current trends in tire technology you may not have been aware of: Tall, skinny tires are coming back. If you’ve ever ridden a beach cruiser bike vs. a racing bike, you know that skinny ...

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, an...

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 i...

Your tires are a pretty big investment. Even with the cheapest set of tires, you’re going to be spending upwards of $400 on the tires, mounting, balancing, disposal fees and taxes. Since you laid down that kind of money, doesn’t it just make sense to make sure you get the most miles possible out of them?  Here’s some advice on long tire life:   • Regularly check your tire pressure. This one is really, really important. Underinflated tires will wear  unevenly and reduce your fuel economy ...

In a lot of parts of the country, the winters are tough enough that all-season tires just won’t get the job done. All-season tires are a compromise; they offer good year-round traction with a quiet ride, good handling and road manners. They tend to perform well in wet weather and light wintry conditions, but when the snow is more than a couple of inches deep, all-season tires are out of their league. That’s when it’s time to consider winter tires.    Today’s winter tires are a long way...

Winter tires versus all-season tires…which is the right choice for you?   The two designs are quite different and deliver different levels of performance and winter-weather traction, so let’s discuss.  • All-season tires are designed as an all-around compromise. They feature a tread pattern that evacuates water from the tire’s contact patch to prevent hydroplaning, with plenty of small, textured slits (sipes) to add extra biting edges for traction in wet or slushy conditions.  ...
