Types of Tires: Which Should You Use?
While there are many types of vehicles to choose from, each type of vehicle excels in one way or another, but certain sacrifices are made. For example, a sedan might be a comfortable and thrifty commuter, but it would fail miserably on a mountain trail.
Similarly, many types of tires are available, each one balancing a number of factors — traction, ride comfort, road noise, lifespan and fuel economy are just a few of these. For each tire, manufacturers use different combinations of rubber compounds, tread blocks and tire construction to deliver the required characteristics.
These tires are meant to be driven in summer. They offer good traction in high temperatures. Grand touring summer tires offer a balance of wet and dry traction, exceptional ride comfort, and low road noise. Extreme performance summer tires excel on dry pavement, but sacrifice wet traction and ride comfort to get there. Summer tires’ hard rubber compounds become extremely hard in winter, offering near zero traction on anything but dry pavement. Sports cars and some sports trucks may benefit from using summer tires.
Snow and winter types of tires are, as the term suggests, meant to be driven in winter, even from late fall to early spring. The softer rubber compound remains pliable and delivers traction in the cold, even on ice. Tread blocks are spaced wider and deeper to cut through snow and slush to firmer surfaces below. Studless ice & snow tires offer better ice and snow traction, while performance snow tires offer better dry pavement traction. Winter tires’ softer rubber compounds become extremely soft in summer, improving traction but wearing out much faster. If snow is expected in your area, practically any vehicle can benefit from a set of snow tires, sedan, truck, sports car or SUV.
All-season tires offer a good balance of summer wear resistance and winter traction on dry, wet or snowy surfaces. At the same time, though, they don’t particularly excel in any one area. Grand touring all-season tires offer the best comfort and all-around traction, while an ultra-high performance all-season tire might sacrifice ride comfort and lifespan. When you ask for tires, unless you specify otherwise, these are usually the tires suggested for your car. It’s a good option for both budget and safety on almost any vehicle.
Run-Flat Tires (RFT)
These tires are usually fitted to vehicles with no spare tire, often on sports cars where ride comfort is less of a consideration. The stiff sidewalls of a run-flat tire will help you get off the road or to a garage without ruining your car. If you have a flat tire, though, do not exceed 35 mph speed or 50 miles distance. Traction and handling will be reduced until you get your tire replaced.
Low Rolling-Resistance (LRR) Tires
Fitted to many hybrids and commuters, low-rolling-resistance tires are easier to roll than typical tires, so they reduce drag on the vehicle. The end result is a 5–15 percent improvement in fuel economy. Today’s LRR tires are nearly indistinguishable from non-LRR tires in terms of traction, road noise, ride comfort and lifespan, so they are a good option for any vehicle they can fit.
We haven’t covered all types of tires in the spectrum — these are just the basics — but this will give you enough information to get started.
