Well, my son's got summer tires and winter tires (my bad, I really thought we were getting all seasons), and sure he loves them. But we only have so much room and money for all of us to be running different tires, and then around here there's the big question on when it's time to change over. It never fails after the Kid changes to his summer tires, he needs to use my car one or two more times.
What was NOT in my budget was new brakes though... I kinda had a feeling I'd need them soon, but the tire guy called me at work and told me they were down to 10% all around, so there went another $400. Ouch!
