There are several benefits to changing out your winter tires when the weather is getting warmer:

1. Improved fuel efficiency: Winter tires are designed to provide maximum traction and grip in cold and snowy conditions. However, when the weather becomes warmer, the softer rubber compound used in winter tires can wear down faster, resulting in reduced fuel efficiency.

2. Better handling and performance: Winter tires are optimized for snow and ice, and their design and tread pattern can reduce handling and performance on dry and warm roads. By switching to summer or all-season tires, you can improve your car's handling and performance in warmer weather conditions.

3. Longer tire lifespan: By using winter tires only during the colder months and switching to summer or all-season tires in warmer weather, you can extend the life of both sets of tires. This can save you money in the long run by reducing the need for more frequent tire replacements.

4. Safety: Using winter tires in warmer weather conditions can be dangerous because they are not designed for those conditions. Winter tires may not provide adequate grip and handling, which can increase the risk of accidents.

Overall, switching to summer or all-season tires when the weather gets warmer can improve your car's fuel efficiency, handling, and performance while also extending the life of your tires and promoting safety on the road.
