Bicycle Tire FAQ

There are a large variety of bike tires available on the market from various manufacturers. Different types of tires are intended for different riding applications. Choosing the correct tire, and maintaining it properly, will improve the quality of your ride and increase your safety.

What Type of Tire Is Right for Me?

This depends entirely on what type of bike you own, and how you plan to ride it. Consider the tire's tread pattern. If you only plan to use your bike for on-road commuting, look for a tread pattern that is smooth in the middle, and slightly knobby on the edges. This will allow for low rolling resistance and additional traction while cornering. If you ride a road racing bike, a very low-profile tread pattern, without knobs, is desired. Most off-road mountain bike tires will feature a completely knobby tread pattern

How Much Air Pressure Is Necessary?

This depends on a few factors: your weight, the type of terrain you're riding, and your skill as a cyclist. Surprisingly, the recommended tire pressure listed on the sidewall of your tire is largely irrelevant. If you are a heavy rider, more pressure will be necessary to support your weight. If you ride over rough terrain, consider lowering the air pressure slightly to provide a more comfortable ride. Skilled riders can get away with lower tire pressure finessing the bike over rough patches to avoid pinch flats.

Should I Worry About Hydroplaning?

No. Hydroplaning is a concern only for automotive tires. Bicycles simply can't hydroplane, for a number of reasons. First, bike tires have a rounded contact area, pushing water to the sides. Bicycle tires are also relatively narrow, minimizing the amount of water present underneath the tire. The high-pressure of bike tires also helps to squeeze water out from under the tire. Finally, bicycles simply don't travel fast enough to make hydroplaning possible.

How Important Is the Tire's Weight?

This depends on what sort of riding you intend to do. Many bike manufactures, and tire manufacturers alike, will tout the low weight of their products. If speed is a top priority, light tires are important. This is because "rolling" weight, defined as anything moving on the bicycle during riding, including the wheels and tires, will slow you down more significantly than stationary weight, such as your handlebars or seat post. Keep in mind that lightweight tires are generally more expensive and less durable than heavier tires.

When Should I Replace My Tires?

Cyclists often make the mistake of replacing tires too quickly simply because the sidewalls look old. Riding on old, worn tires for too long will sacrifice both safety and ride quality, it's true. But the truth is in the tread. Compare your tires to a fresh set of the same make and model at the local bike shop. If the tread of your tires is significantly worn, or you experience frequent flats or loss of traction while cornering and accelerating, it's time to purchase a replacement.
