STUTTGART - Daimler-Benz reinstated Goodyear as a tire supplier 10 days after it recalled 1,500 Mercedes-Benz A-class cars.
The Goodyear tires originally specified for the A-class Classic trim had soft sides. Engineers blamed the tires for instability in the Scandinavian moose avoidance test.
Goodyear and Mercedes engineers developed the GT2 tire together, and both say that the new specifications solve the problem.
In the test conditions, the lateral stress on the tire caused the tire sidewall to roll under, to the point where the wheel flange touched the ground, causing an immediate overload on that corner and flipping the vehicle.
On 28 October, Daimler announced that it had temporarily suspended delivery of tires from Goodyear. It recalled the 1,500 cars that had been sold with Goodyear tires and replaced them with Continental or Michelin tires.
Now Goodyear is again supplying the A-class. Goodyear said there was no disruption in supply.
Besides the Goodyear GT, the Continental EcoEP and Michelin Energy XT1 are fitted to the A-class in the standard 175/65 R15T size.
Goodyear, Continental and Pirelli SpA are suppliers of the optional 195/50 R16H size, with their Eagle Touring NCT3, SportContact and P7000 models, respectively.
