A general rule of thumb for someone that is looking to run a summer tire year round is will the vehicle be used when temperatures are below 40 degrees consistently. For example, on those early mornings or late nights when the temp gets into the 30s the summer tire would not perform well. Typically summer tires are more performance-oriented and have a shorter tread life. The all-season tire can handle the hottest summer climates and coldest winter climates. All-season tires can handle light snow as well however if you are in a climate that receives a modest amount of snow a winter tire will be your best option for winter traction and then the all-season or summer tire during the warmer months.
Take a look and compare some of the tread pattern differences on a popular all-season tire, summer tire and winter tire below.
