![]() ![]() The tire compounds are harder and the tread patterns more pronounced. You can expect higher mileage and better performance in wet conditions. They still provide good grip, but riders of this kind of bike tend to cover greater distances and in all types of weather. Sports tourer, and tourer/cruiser: These motorcycle tires are something of a compromise. Basically, these tires are very sticky but short-lived! ![]() They’re also made of a softer compound to give better grip, though this results in reduced mileage.

(73W) or a similar code in brackets is the load rating.Other codes you might see include the following: An H-rated tire at Z-rated speeds could fail, with potentially dire consequences. However, you must never go the other way. You could get better grip at the expense of faster wear. You can always go to a tire with a higher speed rating, from H (up to 130 miles per hour) to Z, for example. Match those and you know you’re getting a tire that will fit and is of the correct speed rating. If it’s a bias-ply tire, there is no marking here. Z is the speed rating in this case, good for speeds above 149 miles per hour.55 is the aspect ratio, also called the profile height.Let’s look at some typical motorcycle tire markings: 180/55 ZR-17 If you check the sidewall against the specifications, you know you’re getting it right. Some online suppliers offer charts to check if the tire fits a particular make and model of motorcycle, but errors are not unknown.
