    Default Corvette ZR1 Sets New 7:19 Nurburgring Record



    To showcase just how much a few small changes can mean, Chevrolet took the updated 2012 Corvette ZR1 to the Nurburgring, knocking 6 seconds off the car's previous best time set back in 2008. The new 7:19.63 lap time was set by Corvette engineer Jim Mero and is a solid three seconds off the Viper ACR's best, but its just shy of the production car record set by the Porsche GT2 RS at 7:18. (Faster lap times do exist by a Radical and the Gumpert Apollo, but it's not hard to argue that those cars aren't true production models).

    Corvette credits much of the car's added performance to its new Michelin Pilot Sport Cup Zero Pressure tires, which provided an 8 percent gain in lateral acceleration, as well as improved braking. The new tires are available on the flagship 638-hp ZR1 as well as on the 505-hp Z06.

    wtf is a zero pressure tire?

    "I can't make you look stupid any more than Betty Crocker can bake a cake out of fuckin' thin air. It's not that I want to be an asshole, it's just that it comes so easily and I lack either the restraint or good will to say nothing at all."

    The MICHELIN® Pilot® Sport Cup ZP benefits from several generations of
    Michelin run-flat technology, which is especially efficient in
    enhancing race-tire performance characteristics. Michelin has turned
    the technology that enables a tire to run for a limited period without
    air pressure into an asset on the racetrack. Key features of the Pilot
    Sport Cup ZP tire include:
    • Asymmetric run-flat sidewalls optimize tire rigidity (stiffness) in
    the same manner as racing slicks. The run-flat inserts distribute
    sidewall rigidity for amplified lateral grip and peak cornering
    performance with precise control and steering.
    • The supple outside sidewall provides a large and reflexive variable
    contact patch similar to the racing slicks used on the Corvette Racing
    C6.R in the 24 Hours of Le Mans.
    • The reinforced inside sidewall provides the extra-tuned rigidity to
    support extreme cornering forces and transmits the extraordinary
    braking and acceleration torques produced by Corvette’s ample Brembo
    carbon-ceramic brakes and substantial 638-hp LS9 or 505-hp LS7
    powerplants.
    • Unique tuning of the production tire’s variable contact patch
    enables drivers the ability to get on the power more quickly when
    exiting corners, confident of grip and handling throughout the course
    for faster lap times.
    • A new racing-compound arrangement raises the limit of world-class,
    DOT street-legal and track-ready tire grip without reducing wear. The
    compound resists uneven rib wear created by continuous lapping in one
    direction.
    • The custom-tuned, variable contact patch supports continuous control
    and progressivity in the most demanding track and road situations.

    Run flat technology that can run for up to 50 miles at 50 miles an hour, even with a hole the size of a golf ball in it.

    Zero Pressure™

    The tire that can survive without air.
    Run flat tires for ultra high-performance vehicles have been around for years. But the real engineering feat was to develop a tire with run flat capability that fit on sedans and coupes. Always up for a challenge, Michelin developed the Zero Pressure™ tire. This unique system is designed to fit on cars like Mercedes, BMW, and Honda Accord. Even with a hole the size of a golf ball, the Zero Pressure™ tire will allow you to drive up to 50 miles at 55 mph. Never get stuck on the side of the road again.

    Seems very specific and elite.

    Im with the others here though, never heard of zero pressure, and I have driven a couple cars with runflats, one being a beamer and hated them, loud and felt like shit and were replaced under warranty twice in two years because of uneven wear.

    Lot's of reasons.

    The Radical - not street legal here, so who cares.
    Gumpert Apollo - they build far too few for it to be seriously considered a production car.

    And yes, both are mean-ass vehicles that you'd never want to drive anywhere but on a race track.

    Zero pressure is just the name. My Eagle F1 super cars on my old set were cut and if it wasn't for the tire pressure sensor, I wouldn't have even noticed it had no pressure. I have both run flats and non run flats. I use the run flats for the daily driving and regulars for the track. I've noticed with run flats (mainly with the reinforced walls) I can turn my faster with greater G-force than regular tires. For launches or accelerations, the regular tires were better. It is a bit stiffer driving with run flats but I never hear the noise probably because my exhaust drowns it, lol.

    Given, the car has no spare tire, I prefer the run flats, hahaha. But the price hurts more than anything else.
