Last week, I tested eco-oriented Passenger All-Season tires -- the Continental ProContact with EcoPlus Technology, Goodyear Assurance Fuel Max, Kumho eco Solus HM KR22 and the Michelin HydroEdge with Green X -- on our 6.6 mile road course.
The road course was dry, sunny and temperatures were in the low 70s. I found all four tires to be very comparable in ride quality and noise. In handling, only the Kumho was a bit sluggish. The other three tires handled well for passenger tires.
Later, I was on the test track where conditions were sunny, dry and 79 degrees. I found the Michelins to be the best in braking and handling, the Kumho was the worst and the Continental and Goodyear fell in the middle.
Overall. I would place the Michelin first, the Continental second, the Goodyear third and the Kumho fourth.
Look for complete test results online soon.
