Porsche offering new tire option for Carrera GT

Let's face it: finding new tires for older cars can be challenging if tire manufacturers have stopped carrying the right sizes (this writer went through Hell to find a set of 205/60-13s). But what about tires for low-volume supercars, which use sizes that often won't fit on high-volume production vehicles? The Porsche Carrera GT isn't that old and tires are still available in the correct sizes, but the German automaker has shown its support of keeping them on the road by working with Michelin to give owners yet another tire option. Enter the Carrera GT-specific Pilot Super Sport.
It's common knowledge that tires are one of the most important pieces of the performance puzzle, and Porsche claims that the PSS tires, sized 265/35ZR-19 front and 335/30ZR-20 with Porsche's "N0" rating, will improve the Carrera GT's handling and stability all the way up to its claimed top speed of 205 miles per hour. That's important for a car with razor-sharp handling characteristics. They'll also net drivers a 10-percent increase in fuel economy on regular roads and up to 20 percent on racetracks, Porsche says.
The PSSs use cutting-edge tire technology to harness the Carrera GT's 610-horsepower. They have a dual-compound tread that's different from the inside of the tire to the outside, which, Porsche says, helps steering precision and increases maximum grip. Aramid fibers, which are lightweight but just as strong as steel, are used in the tire's belt to reduce unsprung weight.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.

Porsche digitally dissects its 918 Spyder for your viewing pleasure

At this point, you'd think we'd know all there is to know about the 2015 Porsche 918 Spyder - except what it's like to drive - but Porsche has released a new video giving us a more in-depth look at its new plug-in hypercar all the same. The animated video gives us numerous cutaway looks at the 918 Spyder while giving a visual demonstration of the car's four hybrid driving modes.
Though nowhere near as exciting as watching the 918 blast around the Nürburgring in record time, this new video is nonetheless both interesting and informative. Scroll down to watch the video yourself, and be sure to check out our live gallery of the production version of the car along with a stock gallery.
