In Podcast #337, John Davis and the MotorWeek crew discuss three very different vehicles. First off, we spent two weeks with the V8-powered Jeep Wrangler 392 Final Edition (but it is really the FINAL Edition?). Then we dive into a first drive with the revamped Buick Enclave three-row crossover. And we finish up with some recent track time in the Subaru WRX tS, an almost STI-like model of the WRX. But before that, John sat down with TJ Campbell, TireRack’s Tire Information and Testing Manager, on what you need to know about winter tires!
