In this episode, we learn that Tire Rack, America’s Tire and Discount Tire are all the same thing! But, more importantly, they now have a giant tire testing facility in Texas: Treadwell Research Park – an expansive property with dirt and mud trails, rock crawling, water crossings, serious grades, an absolutely enormous skid pad (that can be completely submerged in 2 mm of water in no time thanks to a pair of huge reservoirs and some seriously powerful pumps) and even a wet slalom course. Jason experienced all Treadwell had to offer behind the wheel of a 4-door Jeep Wrangler and BMW 330i and reports back.

We’ll learn that at America’s Discount Rack you can get free tire rotations (with tire purchase) and free flat repair (no purchase necessary!). But they don’t hand out these services out of the kindness of their tire-loving hearts. It’s all part of Treadwell’s plan to collect and analyze all kinds of tire wear data to help customers make informed decisions when buying new tires and make better tires. They’ll collect information about a tire’s make, model, mileage, geographic location and more to find what compounds and tread patterns are best for specific use cases and guide customers to the best choice for their vehicle, driving style, climate, and location. For instance, they have discovered that folks living in twisty, hilly western Pennsylvania go through tires 20% faster than folks living in Nebraska. Derek suggests Treadwell implement a tire wear score so enthusiasts can compare notes and compete for total tire destruction domination.

Similar to Treadwell Research Park (and Tire Rack’s other testing facility in South Bend, Indiana), Derek had the chance to experience a flooded skid “pan” at the CHP’s emergency vehicle operations course (EVOC) training grounds driving in Ford Crown Victorias and Dodge Chargers.

Jason Fenske of Engineering Explained has been on a mission to teach the world about the importance of tires, and recently pitted a F80 BMW M3 Competition on mid-grade tires against a diesel Chysler PT Cruiser wearing fresh Continentals. Science ensued.

Tires are indeed very important – and while some *coughpirellicough* will grip like no other, they tend to disintegrate in short order (and dramatically so). But they’re not all bad – the guys have kind things to say about the Cinturato CN36 and CN12. But the Carmudgeon tire of choice remains Michelins and Vredsteins, which are mounted on everything from Jason’s e-Golf, the Van, Jynah, the Ferrari 308, Derek’s R129, and even Jake’s wife’s Crosstrek. The guys will also discuss the Avon CR6ZZ, Trofeos and Cup 2s. Plus the Michelin AS3+ on Jason’s Mom’s Golf that wore down unusually quickly – this right after he had just replaced some 2-year-old cracking Hankooks with them. Perhaps his mom’s regular and sustained driving at 100 mph is to blame…

We’ll also cover cheap lighting from oh, oh, oh, O’Reilly’s, Wagner halogens, and automotive lighting gemstones from Carello and Marchal. It’s all in the details!
