In 1953, Chevrolet introduced America's first true sports car with the revolutionary sleek look of the Corvette. American's have been enamored with this vehicle ever since its humble beginnings when there was no manual transmission made that could handle its unbelievable 150hp. Things have changed since every model came with a two-speed Powerglide automatic transmission to the roaring 430hp V8 used in today's C6 models. Most current C6 Corvette (2005-2013) models are equipped with run-flat tires.
Frequently I hear from C6 Corvette owners: "What are the longest lasting run-flat tires?" Switching to an all-season rubber compound can significantly increase treadlife. For instance, the Max Performance Summer Michelin Pilot Sport PS2 ZP has a UTQG rating of 220, while the Ultra High Performance All-Season Michelin Pilot Sport A/S Plus ZP has a much higher UTQG rating of 500. Many C6 Corvette owners are willing to give up a bit of ultimate grip in order to switch to run-flat tires that can wear upwards of 30% longer. The two most popular Ultra High Performance All-Season run-flat replacement tires are the Michelin Pilot Sport A/S Plus ZP and Bridgestone Potenza RE960AS Pole Position RFT.
The Pilot Sport A/S Plus ZP (Zero Pressure) is the Ultra High Performance All-Season run-flat tire member of Michelin's Pilot family of low profile, high-speed tires. Developed in the Original Equipment sizes for Chevrolet Corvette C-5 and C-6 coupe and convertible sports cars, the Pilot Sport A/S Plus ZP is designed to temporarily support the weight of the car even after a loss of air pressure, as well as combine enhanced all-weather performance, wet grip and treadwear along with year-round traction, including in light snow.
Bridgestone's Potenza RE960AS Pole Position RFT tire is developed for drivers looking for enhanced ride quality and all-season traction for sports cars, sports coupes and performance sedans originally equipped with O.E. run-flat tires. It features Bridgestone 3G RFT Technology designed to offer almost the same riding comfort as conventional tires while providing temporary extended mobility for a distance of 50 miles at up to 50 mph even after a puncture has allowed complete air pressure loss. Potenza RE960AS Pole Position RFT tires provide year-round driving flexibility by offering predictable handling, traction and control on dry and wet roads.
When it's time to replace the tires on your Chevrolet C6 Corvette, be sure to shop by vehicle and view the list of longer wearing all-season run-flat tires.
The Continental ExtremeContact DWS has been a customer favorite for almost five years. It has stood the test of time, especially with its good ratings in winter conditions. Bridgestone's Potenza RE970AS Pole Position was the latest entry to threaten Continental's number one ranking. We put them up against each other in a test cycle where we run them on a wet and dry track, as well as on the road. Our team favored the Bridgestone in the meeting. The Bridgestone gives a better overall performance feel and traction in both the wet and dry, especially in the track events which are designed to simulate emergency maneuvers.
In an earlier test, we noted we'd like to see an improvement in winter conditions where the Bridgestone was concerned. This happens to be the Continental's strong suit and as it turns out, the ace in the hole. When the Bridgestone initially debuted on the survey results, it came it in at number one. The Bridgestone takes top honors in wet and dry traction, as well as cornering and steering response. However, as owners had some time to experience the winter elements, the ExtremeContact DWS rose back to the top. This Continental tire betters the competition in traction in light snow, deep snow and on ice.
