When the Maxxis competition tires are exposed to temperatures below 32ºF (0ºC), the unique racing rubber compounds used in these tires will lose their flexibility. This loss in flexibility can lead to potential cracking and other damage to the tire. An example can be seen below:

Figure 1. Tread Area Cracking Due to Colder Temperatures

TO MINIMIZE THE CHANCES OF THIS HAPPENING, CONSUMERS AND INSTALLERS ARE ADVISED TO FOLLOW THESE INSTRUCTIONS:

1. Do not move or operate the car with these tires mounted on the vehicle if conditions are below 32ºF (0ºC). ALWAYS INSPECT FOR SIGNS OF CRACKING! NEVER USE TIRES THAT HAVE CRACKED!
2. Always store these tires indoors and at temperatures above 32ºF (0ºC).
3. Avoid transporting and handling these tires in conditions below 32°F (0°C).
4. Do not mount or dismount these tires when the surrounding work area temperature is under 50ºF (10ºC). ALWAYS INSPECT FOR SIGNS OF CRACKING! NEVER USE TIRES THAT HAVE CRACKED!
5. Before mounting or dismounting, store these tires indoors for at least 24 hours in a temperature-controlled area of 68ºF (20ºC) or warmer. ALWAYS INSPECT FOR SIGNS OF CRACKING! NEVER USE TIRES THAT HAVE CRACKED!
6. Remove these tires from the vehicle and deflate to half the normal air pressure during prolonged periods of non-use or storage.

The Maxxis Victra Sport EV is an Ultra High Performance Summer tire designed for summer conditions when ambient temperatures are above 50ºF (10ºC). Use in colder temperatures may compromise the tire’s performance in areas such as tire traction. Special care is also needed for Maxxis Silent Foam in colder climates. If Maxxis Victra Sport EV tires are exposed to temperatures below 0ºF (-17ºC), the adhesive on Maxxis Silent Foam that bonds to the tire’s inner liner will lose its flexibility and tackiness. Therefore, driving the Maxxis Victra Sport EV in cold temperatures may result in Maxxis Silent Foam detaching from the tire’s inner liner and causing tire imbalance/vibration, negatively affecting noise-absorbing performance. A quick visualization of how the foam attaches to the tire can be seen below.

TO MINIMIZE THE POSSIBILITY OF MAXXIS SILENT FOAM DETACHING, CONSUMERS AND INSTALLERS ARE ADVISED TO FOLLOW THESE INSTRUCTIONS:

1. Do not move or operate the car with these tires mounted on the vehicle if weather conditions are below 0ºF (-17ºC).
2. Always store these tires indoors and at temperatures above 0ºF (-17ºC).
3. Avoid transporting and handling these tires in conditions below 0ºF (-17ºC).
4. Do not mount or dismount these tires when the surrounding work area temperature is under 0ºF (-17ºC). ALWAYS INSPECT MAXXIS SILENT FOAM BEFORE SERVICE.
5. Before mounting or dismounting, store these tires indoors for at least 24 hours in a temperature-controlled area of 50ºF (10ºC) or warmer. ALWAYS INSPECT THE CONDITION OF MAXXIS SILENT FOAM BEFORE SERVICE.
