The tread design, patterns and depth on typical Z speed rated tires as well as compounds used have a profound affect on traction, depending on road surface conditions. The rating isn't the point. The tire design to achieve the rating sure as hell does affect traction under conditions the tire wasn't designed for.
Precisely.Tire compounds are a major component of the traction issue. Most (but not all) high-performance tires are built with compounds that are not meant for use under 40 degrees, turning them into expensive but useless blocks of rubber from late fall to early spring.
Well that didn't take long.
It's been less than a month since Chevrolet revealed the 2014 Corvette Stingray, and already one has turned up wrecked. Since the new Corvette isn't on sale yet, chances are someone at General Motors will have a sizable expense report to fill out.
Caught by a poster at Digital Corvettes, the photo was supposedly snapped recently in Arizona, with the original shooter's commentary: "Cop had just arrived. Car is in worse shape than looks. Hit guardrail on left and bounced back to rocks." Automakers often run hot-weather and handling tests in Arizona, and this copy wears the Michigan manufacturer license plates that a GM-owned prototype would carry on public roads.
What I see there is not really a prototype, but a late pre-production car. Noting the apparent lack of instrumentation, I would say the odds of it being either a test driver or a development engineer doing tests is quite small. On the other hand, an exec or a member of the media- that would be much more likely. Especially the media part.
UPDATE: According to Chevy spokesman Monte Doran, this was a GM test drive gone wrong: "During evaluation, the driver caught the inside tire caught the edge of the pavement during a tight corner, leading to the accident. Thankfully, no one was hurt, the car received only minor damage, and no citations were issued."

Bought a 2013 Ford Fusion today. First time in 16 years that I do not own a truck.
How long ago?
