I recently finished a Real World Road Ride on the ecologically oriented Passenger All-Season tires and I was shocked at the results! The test included the new Kumho eco Solus HM KR22, Continental ProContact EP, Michelin HydroEdge with Green X and Goodyear Assurance Fuel Max. The test was conducted on a very hot, dry day.
My ride started with the Kumho eco Solus HM KR22. The tire was surprisingly quiet and comfortable throughout the entire road ride. It seemed to have better than average steering feel, but did not compromise ride quality. This tire is designed to have a long treadlife, and to be quiet and comfortable. All in all, a very impressive tire.
Next, I tested the Goodyear Assurance Fuel Max. This tire was quiet and comfortable, but did not absorb impacts as easily as the Kumho. It had decent steering feel and handling characteristics, but I would say this tire was second to the Kumho. Just off the mark.
The third tire I tested was the Continental ProContact EP. This tire was quiet and comfortable, but did not absorb impacts as easily as the Kumho. It had decent steering feel and handling characteristics, but I would say this tire was second to the Kumho. Just off the mark.
Finally, I drove the Michelin HydroEdge with Green X. I was very disappointed. The tire was extremely noisy and felt very harsh on the impacts. It had good steering responsiveness, but that came at the expense of ride quality. I could not believe the high road noise that the tire created on normal asphalt and on concrete it was horrible. I am surprised by how highly ranked the HydroEdge is in the consumer survey. I was VERY disappointed.
There will be more to come! Stay tuned to Tire Rack for the complete test results.
