DAYTONA BEACH, Fla.—Goodyear will add several new sizes to its ultra-high-performance tire lines over the next several months.
Beginning in March, the Akron-based tire maker will add 11 sizes in 16-, 17- and 20-inch rim diameters to its value-priced Z-rated Eagle HP Ultra Plus tire line, officials announced at the recent Rolex 24 hours at Daytona race.
Meanwhile, Goodyear's top-end Eagle F1 Supercar ultra-performance tire, which is original equipment on the 2001 Corvette Z06, will soon be available in additional sizes to fit other late-model Corvettes.
Bob Toth, Goodyear marketing manager of auto tires, said plans call for adding four sizes by summer to fit 1988 and newer Corvettes: 275/40ZR17, 245/45ZR17, 315/35ZR17 and 275/40ZR18.
"Ultra-performance is where we really shine," Mr. Toth said, adding it's also the most profitable segment of the auto aftermarket.
Ultra-performance tires owe much to the world of auto racing, which has contributed many of their engineering improvements, Mr. Toth said. Only 15 years ago, even the most advanced race tire couldn't keep pace with today's Eagle F1 Supercar ultra-performance street-approved tire.
Equipped with such tires, the new Corvette Z06 is capable of going from 0 to 60 mph in four seconds and delivering more than 1 G of cornering acceleration, Goodyear said.
The Z06's P265/40ZR17 (front) and P295/35ZR18 (rear) Eagle F1 Supercar tires are larger than the Eagle F1 GS EMT run-flat tires on the 2001 Corvette coupe and convertible.
Despite their size, the ZO6's four tires weigh 23.4 pounds less than their run-flat counterparts. Goodyear officials said the weight savings come from removing the run-flat reinforcements as well as using lighter weight components.
Since the Z06 Corvette is not equipped with a spare tire, a General Motors Corp. tire inflator kit is included to seal punctures up to 5 mm in diameter.
