Bike Tyre Buying Guide: Types & Grades of Bike Tyres

Bike Tyre Buying Guide: Without a wheel, a motorcycle would not exist. The simple looking, least demanding part of your machine takes everything that comes into your way. Think of running barefoot on tarmac all day and it does the same for you.

Every tyre size these days gets displayed as X/Y-Z. These three numbers speak clearly about the profile of a tyre with ‘Z’ being the rim size that it needs for proper fitting.

X is the width of the given tyre in millimeter while Y comes out to be a measure of sidewall. It is a relative value and depends directly on the width of tyre. For example, a person using 100/100-18 tyre will have the same sidewall as a person using 200/50-18 tyre. Here, Y is 100% and that means equal sidewall as the width.

On the second tyre, the 50% Y means the same sidewall as the first tyre in theoretical terms. After understanding the measurement, types are also equally important.

All three of them have higher traction than MRF tyres but that also results in shorter tyre change intervals. These generally last up to 10,000 km. All you need to do is buy and get them replaced without any special change in alloy wheel.

# Why brands use Pirelli tyres on some of the Indian bikes?
