In this photo we have a 180/55 ZR17 (73W) tyre, whichmeans it’s 180mm wide, and the profile height is 55% of that, so 99mm.

Crossply (or bias) tyres have a relatively simplestructure with sturdy sidewalls and are particularly suited to off-road use asthey resist impact well.

The legal tread depth limit for motorcycles, mopeds and scootersover 50cc in the UK is 1mm across three quarters of the width of the treadpattern, and with visible tread still remaining on the other quarter.

It sounds obvious, but the most important point is thatthe tyre must be the right size for your motorcycle, with the correct speed andload ratings.

Motorcycles cannot walk without tires, almost without exception, almost all motorcycles need tires. How much do you know about such an important tire?

The two tires of motorcycles play a key role. It can be said that tires are the only "bridge" connecting the road to the vehicle. Many people do not pay attention to motorcycle tires, and do not pay attention to maintenance.
