I am not sure car drivers realise how new tires feel.
A motorcycle relies on its tyres. Many people just replace there tires once the tread has gone but this is often a mistake. As the tyre is worn it becomes mishapen, and this affects handling.
The contact patch on a motorcycle is about the size of a credit card, thats a very small area to trust your life too. Once the handling starts to go off, replace your tyres. A bike with fresh tyres is like a new bike.
