The Pulsar 220 Back tyre life span depends on many factors, including what type of tyres you use, how much you weigh, the conditions you ride in, front vs rear tyres, etc. As per the law, the tyres for trailers with a special permit for the maximum speed of 60 mph should be no older than six years. In all other cases, it is up to the driver to decide when the tyres have exceeded their lifespan. Commonly, the Pulsar 220 tyre life in India is six years. This is because the bike tyres suffer the wear and tear of ageing from the inside as well as outside. Replacing it after six years will be safer even if you don't see any tread loss or visible damage on the tyre's surface.
