Tiresome Details

When we ride our motorcycle, the two things we tend to take for granted but are the only two things that keep us rolling, are our tires. There are 2 types of tires, bias and radials. Bias is the type of tire found on older bikes, and the radials are the types found on newer bikes.

The radials tend to be better handling and run cooler than the bias type tires. However, due a shorter sidewall they have less flex. Also with the lower profile, they may impact handling and have a lower available load rating that the bias tires may have.

If your bike came with bias tires, they may not be able to use radial tires due to the narrower rim size and the frame may be too flexible for the higher capability of radial tires. You also may not be able to "stuff" all that tire in the same place of the old bias. There may not be the clearance between the driveline and the lower height may reduce your cornering clearance. Make sure you check with a tire specialist before purchasing the tires to make sure they are suitable for your type bike. You also need to consider the type of riding you do. The harder compound tire will last longer but may not be as "sticky" as a softer compound tire. The softer "stickier" tire will corner better but not last as long. Pick the correct tire for your specific riding style and type bike.

The side wall tells a history of the tires, for example a 120/80/17 tire means the 120 is the tire width in millimeters. The 80 states that the tire is 80% tall as it is wide and the 17 means it goes on a 17" rim. It also includes the recommended air pressure, but you should also consult you owner's manual as well.

Over and under inflation are important things to look for while checking your tires. Overinflation means too much air pressure in the tire, which makes the tire stiffer and causes a harder ride. This will also give you less contact area to the road surface. Underinflation means too little air pressure in the tire, which makes a tire softer which causes a larger contact surface, higher tire temperature and higher wear. It may also cause handling problems.

Check your tires often for correct pressure, side wall cracks or foreign objects imbedded in your tires. Tires, they do your body good&ldots;&ldots;
