I don't really need them on the car right now, it's early March and I usually switch by 4/1 but going to the track I like to have them as they can act as a spare in case I damage one of my 200tw track tires so I don't loose out on the weekend and work well for rain sessions. It's possible we could see temps dip back into the 30s but really, it's not an issue if it's dry and I can just drive my other car with all seasons.Awesome tires. They use them at the BMW Performance Center in Thermal![]()
