How a Rusty 1970 Cuda Won the Triple Crown of Rodding.

  How a Rusty 1970 Cuda Won the Triple Crown of Rodding. There’s an old adage seasoned customizers often cite when the query is how to begin a build and that’s to start with the very best example of the desired car one can find. And that's really good advice, but here's an exception to the rule and that's this stunning 1970 Plymouth 'Cuda that took Best Street Machine at the inaugural Triple Crown of Rodding held within the 34th Annual Hot Rod Roundup, hosted by Shades of the Past Car Club in Pigeon Forge, Tennessee. Research Research New Used New & Used Make (e.g. Mazda) Model (e.g.

The Science Behind How Michelin Made Its Best Tire Even Better© Michelin The Science Behind How Michelin Made Its Best Tire Even Better As the standard fitment in many of our favorite performance cars, the Michelin Pilot Super Sport gained a well-earned reputation as one of the best tires available. The Pilot Super Sport's replacement, the Pilot Sport 4 S (PS4S), has big shoes to fill then. In his latest video, Engineering Explained's Jason Fenske goes into the science of how Michelin improved the Super Sport.

The PS4S features an aramid/nylon belt that's designed to help the tire maintain its shape under pressure. This stronger belt effectively gives the PS4S a wider contact patch, which is especially helpful in high-speed cornering. A new tread pattern also helps improve grip by distributing pressure more evenly across the contact patch.

10 Tire and Brake Problems All Drivers Need to Know

  10 Tire and Brake Problems All Drivers Need to Know Because unreliable brakes are the last thing you want.Wide-open acceleration might fun, but slowing down that speeding hunk of metal is much more important. Any driver's safety depends on consistent, reliable deceleration, or in other words, working brakes and tires. These two parts constantly keep your car pointed and moving – or not moving – in the right direction.

Additionally, the PS4S uses a multi-tread compound that uses different materials on the inner and outer parts of the tire. This helps generate more grip in both dry and wet conditions.

Fenske goes into great detail here, helping remove some of the mystery surrounding tire design, so watch his video for more. We'll also have our own review of how the PS4S performs across a variety of conditions, but our writer is busy competing in a certain 24-hour race this weekend. Watch this space.
