So you have winter tires and you are looking for tires for summer time...
Or, you live in a warm climate and do not get winter weather.
Many drivers assume that they need summer tires based on these conditions, however what should be considered is the tread life gain with all-season tires.
If you are an aggressive driver with a sports coupe or sedan, a summer tire with a softer compound may give you the traction you desire. The tradeoff is that you will get far less treadlife with an Ultra High Performance All-Season tire.
If you are a more conservative driver and do not need the dry traction and handling provided by an Ultra High Performance Summer tire, you will likely have a better overall experience and value with an all-season tire even if you do not need winter performance.
