Rotalla S-220 Winter - 215 65 R16 98H

It is generally recommended to install winter tires when the average daily temperature drops below 7°C (45°F), or when winter weather conditions such as snow and ice are expected.

No, these tires are specifically designed for winter conditions. Using them in warmer temperatures can lead to faster wear and reduced performance on dry or wet pavement.

The deep grooves help to evacuate snow, slush, and water from the tire's contact patch, preventing hydroplaning and maintaining grip. The sipes (small slits) provide extra biting edges for traction on ice and packed snow.

The silica compound helps the tire remain flexible in cold temperatures, which is crucial for maintaining grip and traction on cold roads, as rubber hardens in the cold.

Use a reliable tire pressure gauge on cold tires. The recommended pressure for your vehicle can be found on a sticker in the driver's side doorjamb or in your owner's manual.

'98' is the load index, indicating the maximum weight the tire can carry. 'H' is the speed rating, indicating the maximum speed the tire can sustain. Always ensure these match or exceed your vehicle's requirements.

This is expected behavior for a winter tire. Performance is optimized for cold, snow, and ice. Consider switching to seasonal tires once winter conditions have passed.

Winter tires often have a more aggressive tread pattern which can contribute to increased noise. This is normal for this type of tire.

Check tire pressure when cold and adjust to the recommended PSI found on your vehicle's doorjamb sticker. Extreme temperature changes can affect pressure.
