The cornering and rolling forces on each of your tires are different.  If you have a front wheel drive car, the power and most of the force is transmitted to the front tires while the rear tires pretty much just follow along like fixed wagon wheels.  A rear-wheel drive car or truck sends power to the back while steering forces are handled by the front wheels.  All-wheel drive and 4wd have their unique power, steering and cornering characteristics as well.  The point is, your front left tire is ...

With all the tires you encounter every day, it is easy to forget their humble beginning and just how far they have come since the early days of automotive development. Follow along as we recap the incredible evolution that has taken us from simple rubber rings to the products we see today. The tire had rather humble beginnings. In the late 1800's the invention of the automobile necessitated something for them to roll on. Until then, wheels were rolling around on hard wooden rims or metal bands....

Believe it or not, many new vehicles come without a spare tire. Manufacturers have a few different reasons for that, including weight savings, space efficiency, and cost. When you're stuck by the side of the road, though, none of that really matters much, does it?    Instead, these vehicles come equipped with an inflation kit and/or a can of sealant.    Sealant is a gooey substance in an aerosol can that's designed to coat the inside of the tire due to centrifugal force once you get rolling aga...

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...

Don’t let tire problems get in the way this Valentine’s day. How is your tire pressure? Do my tires need to be rotated? Is it time for an alignment? Do I need new tires? While these questions can seem daunting, with the help of tire professionals and various routine self-checks, any driver can maintain proper tire care and not miss that big date this Valentine’s Day. From tire rotations to air pressure, learning what signals might indicate tire replacement or repair is important for every ve...
