R is a designation of the tires construction, in this case meaning radial ply. Apart from radial, the other carcass design is the bias, which is represented by ‘B.’ The ‘16’ value refers to the wheel size, which is the diameter. This tire is made for a wheel with 16 inches diameter. If there’s a specification that you must get right, it’s the wheel size rating. In the same example, ‘67’ denotes the load index. If you pick this tire, you can carry a load of up to 661 pounds. Another vital feature is the last letter, ‘H,’ which denotes the maximum speed that the wheel can support; in our example above the maximum speed is 130 MPH. Apart from the H rating, there are 14 other speed ratings.

Take it from the experts, who’ve had the chance to try out all the latest rubber on a variety of bikes—there is no single best set of tires for any one motorcycle, only the best riding tires for YOUR motorcycle and how YOU use it. Have a sportbike that you use more for sport touring rather than the track? You’re going to want to look into the top-rated dual compound tires for the longest lasting reliability and best cornering performance. Ride a cruiser you use for commuting AND for long trips? You’ll need an all weather tire that performs in any conditions, and touts high mileage durability for consistent handling, mile after mile.
