Yeah. I was going to point that out. When I bought my Smart in 2012, it had the OEM 2008 tires on it. I bought the winter set in 2014, and if I hadn't been so excited about Vredestein making tires to fit, I could have got one more season out of both. (Until this year, the only tires that were available were the OEM Contis and some Kumhos.)
When I got some spare wheels for my winter setup for the ML, they had Michelin tires on them that I figured would last the summer. 3 years later, they still have at least another year on them, I have studded Cooper Discoverers on it while they're legal. (I also don't drive it very much.)
The biggest expense is the extra set of wheels. (FWIW, the Discount Tire I use swaps sets for free, spring and fall, since they're mounted on extra wheels)
