The holidays have a lot to do with smells: the musty scent of the tree after it's been trimmed, the taste of turkey in your nose after it's been set on the table, and the fresh lavender smell of your tires after driving over the river and through the woods to get to Grandmother's house. That's right, the prize for Day 4 of Autoblog's Holiday Sweepstakes is a set of Ultra High Performance Kumho ECSTA DX Aroma tires. Not only does this rolling rubber offer better grip than your standard fare from the factory, but special oils in the tread compound release a pleasant lavender scent after they've been warmed up. After getting a whiff of these, Grandma will want you to do burnouts in her driveway this year.
