The world of tires is evolving. Whether it's making them from recycled rubber or having a removable tread patter than can be switched out, which are two concepts Michelin is championing, there are coming major changes to one of the least-considered but most-important parts of a vehicle.

The Goodyear ReCharge tire concept is a creative take on the possible future of tires and it works similar to your Kitchen Aid mixer. The you want to make fresh pasta noodles, you feed a clump of dough through the mixer's attachment and out the other side comes noodles.

The tire's test takes a compound of renewable materials and feeds it through a series of pipes that feeds it out to the surface where it cures, forming functional new tread. The list of renewable materials includes dandelion rubber and synthetic spider silk. Goodyear says that these materials are strong enough for daily use rather than just a patch job.

The compound would be stored in pressurized canisters within each tire. Goodyear envisions that customers would be able to switch out canisters to meet the tread needs of the vehicle, theoretically allowing the tire to adapt for winter and summer driving conditions.

The concept tire requires no pressurization, meaning that it would never go flat. This feature is a developing trend with tire makers. Michelin debuted a tire last May that is able to be retreaded and also doesn't have to be pressurized.


While the tire is just a concept, Chris Helsel, Senior Vice President and Chief Technology Officer, Goodyear, explained to Engadget that the processes and features shown in the concept may find their way into future Goodyear tires within the next decade.

Future has gotten a new vintage car. The hip-hop star from Atlanta, Georgia has received delivery of a 1971 Chevrolet K5 Blazer that was fully customized by Ringbrothers.

Under the hood is a 6.2-liter LS3 engine that is paired with a 4L80-E transmission. The crate engine was standard in the fifth-generation Camaro SS and C6 Corvette and is now sold as an aftermarket part by Chevy. It delivers 430 horsepower and 425 pound-feet of torque. The transmission is a heavy-duty offering from General Motors, the parent company of Chevrolet, that has been used in everything from the Suburban to a Bentley Continental.

Ringbrothers, a shop in Spring Green, Wisconsin, gave the Blazer a custom BASF British Racing Green paint scheme after restoring the body of the Blazer with 3M products. It rides on gold 18-inch HRE wheels.

"We first started building Blazers a few years back, and they've really taken off in popularity since then," said Ringbrothers co-owner Jim Ring. "There is no assembly line at our shop, as each build is completed by hand, bespoke to the owner's request. There is no other Blazer in the world like this one."

Future's K5 Blazer also has a custom tan interior designed by Upholstery Unlimited and an exhaust provided by Flowmaster.

"We're humbled that people continue to come to us for special projects like this," said Ringbrothers co-owner Mike Ring. "We realize that our customers could get a new Ferrari or Lamborghini but choose us instead. It's an honor we don't take lightly, so we put our heart into each project. We're glad Future appreciates that."

In addition to K5 builds, Ringbrothers has released several K5-specific products, including a glove box door, hood hinges, and a dash gauge bezel. Future's Blazer features those parts, along with a custom carbon fiber hood and custom tailgate with integrated seating. The musician's Blazer also has a JL Audio sound system.

The Ferrari Omologata comes from a strong family tree filled with performance and Italian beauty. It's a one-off model that takes its DNA from seven decades of Ferrari GT tradition. The model has been crafted by a European client.

It's taken two years to complete the model since the presentation of the initial sketches. It's a model that took its inspiration from a variety of sources: racing heritage, sci-fi, and modern architecture.

A Ferrari 812 Superfast is the underlying package of the car, but the designers kept just the windscreen and headlights from the body. They set forth to create a model with smooth volume and undulating reflections. The car's front end is tapered and faced by a flattened oval grille. At the back, the car takes a more muscular stance, has deeply set taillights, and is finished off with a prominent spoiler.

Dressed in a triple layer of Ferrari's Rosso Magma paint and a racing livery the car combines track day prowess with daily drivability.

Inside, the car sports electric blue seats finished in a combination of leather and Jeans Aunde fabric with four-point racing harnesses. The rest of the interior is finished in black.

Unlike modern vehicles, the Omologata does not have a screen in the center of the vehicle, giving the model. a historic tinge. Metal parts on the dashboard and steering wheel are finished with the crackled paint effect associated with the great GT racers of the 1950s and 1960s as well as with Ferrari's engine cam covers. A hammered paint effect so often used in cars such as the 250 LM and 250 GTO finds its way on details such as the inner door handles and on the Ferrari F1 bridge.

The mid-engine car has a 6.5-liter V12 engine, harvested from the 812 Superfast. In that car is generates 789 horsepower and 530 pound-feet of torque. The engine is paired with a seven-speed dual-clutch transmission.

Ferrari isn't divulging the price of the Omologata.
