Bigger wheels and tires are a desirable upgrade for not only the off-road extremist but many everyday drivers as well. For example, you can go to Wal-Mart and count several SUVs in the parking lot with 20-inch rims because even “Glamma” wants to look cool. Tires can really make or break your vehicle in relevance to style and performance. Driving on bad tires can take a toll on your vehicle, and upgrading to new tires can make your vehicle drive like new again. When upgrading to bigger tires y...

Whether it’s the price of gas, the people you spend time with, or the level of satisfaction you have with your job, one thing in life is certain, things change. It may not be a surprise your vehicle, the way it works, and how much it costs has changed significantly over the years. But have you ever thought about how much tires have changed? Before air was introduced into tire designs, they were covered in wood, iron, solid rubber, and even leather. Although these weren’t the most shock absorb...

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....

Ever wonder what the designations stamped on your tire sidewall actually mean? We’d like to break it down for you. Let’s take for instance, “P195/60R15 87S”. This is a full service description of a tire. In this case, “87S” denotes a tire’s load capacity and speed rating. The higher the number, the greater the load capacity – an 87 load capacity means that tire can support 1,201 pounds. Speed ratings range from L (75 mph) through V (149 mph), and an S speed rating means the tire is good...

Every year, about 290 million tires are discarded; of those, about 233 million are recycled in one way or another. Shredded tires can be used for playground surfaces, welcome mats, hot-melt asphalt, bark mulch and even made into building material for “green” construction. But what can you do with your old tires? Here are some ideas: --Fill a tractor tire with sand to make a great sandbox for kids --Hang a tire from a rope as a tire swing --Stack a couple of tires on top of each other, bolt th...

Ever think about all the different vehicles that use rubber tires? Tractors, industrial equipment, everything else that rolls on rubber? Each specialized type of tire requires a specialized design for its specific purpose. Aircraft tires, for instance, have to be very robust and handle a great deal of weight and stress, but for only a short period of time. Aircraft tires are often filled with an inert gas such as nitrogen, for more stable inflation levels, and are designed with specialized fu...

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...
