** Optimum inflation pressure varies from track to track, depending upon track length, surface conditions and machine size.
Dunlop DT4 and K180 Flat Track tires are Tubeless, but an inner tube and rim band is required if using a tube-type rim.
Dunlop recommends that if tire warmers are used they are set at 70°-80°C for 45 minutes to 1 hour (maximum); tire performance degradation may occur if tires are subjected to repeated tire warming cycles, and/or temperatures/times in excess of these.
Width and Diameter are measured on recommended rim.
