Yes, the surface of the road significantly affects the lifespan of your Honda Shine tyres. Rough or abrasive road surfaces can accelerate the wear of even the best high performance tyres. Poorly maintained roads with potholes, cracks, and debris often lead to tire punctures or sidewall damage, while shortening the lifespan of the tires.

The lifespan of a Honda Shine tyre depends on a large number of factors. These include the type of tire, the conditions you ride in, and how often you ride. As a general rule, it's recommended that you replace your Honda Shine tires after examining any signs of wear or damage, such as cracks or cuts in the sidewall. This general rule is applicable to all bikes including Honda Shine.

The warranty on any performance tyres drastically varies depending on the product line as well as model. Whether it's Honda Shine or any other bike, you need to refer to the product page on the Metro Tyres website for more specific warranty information.

Increasing the lifespan of your tires manufactured by Metro Tyres involves proper maintenance, riding habits, and some basic care. Remember that the lifespan of Honda Shine tires also depends on factors like the quality of the tires, the type of rubber used, and the specific conditions you ride in.
