I just finished my road test on the Yokohama AVID ENVigor, the Michelin Pilot Exalto A/S, the Sumitomo HTR A/S P01, and the Firestone Precision Sport. Get ready because here comes my two cents!
I started the test with the Yokohama AVID ENVigor. I must say that I was more than pleasantly surprised with this tire. It was comfortable, quiet, and felt very centered and stable. The steering feel was heavy, but not too heavy, very precise. In the past the Yokohama product has always seemed to create a specific pitch that I found offensive, but the AVID ENVigor did not have this problem at all. As for the overall road manners, I think this might have been the best tire in the test!
Next I went to the Firestone Precision Sport. Not sure what Firestone's goal was when they made this tire, but it was alright. Nothing that I would rant or rave about, nothing really good or bad. If I could make a change to the tire I would make it quieter on the road and give it a heavier feeling to the steering. It would make it feel much more centered on the road. Ranking the tires we tested, I would say that this would finish 3rd in the test, but not far ahead of the Sumitomo HTR A/S P01.
The third tire I tested was the Sumitomo HTR A/S P01. Nice tire for the money. Not the quietest or most comfortable, but I would classify this as a nice value tire. It has better steering feel than the Firestone, but creates at least as much noise if not more. It also does not provide the ride quality to absorb bumps and impacts like the other options. But, for the money, this would be a nice all-season performance-oriented tire, with an emphasis on performance.
The final tire in the test for me was the Michelin Pilot Exalto A/S. I felt that the Pilot was much more performance-oriented than the Yokohama, and did not do as well at handling and absorbing the bumps and impacts in our Indiana roads. It was very responsive and had nice on-center steering feel, but in the BMWs it was not the most comfortable on the road ride. The Michelin did not create much road noise and was very nice when on very smooth asphalt with minimal expansion joints or impacts. It did, however, make the impacts on the road more noticeable than the Yokohama.
Just my two cents, but I have to say I was very impressed with the Yokohama AVID ENVigor and its daily driving road manners. There will be more to come! Stay tuned to tirerack.com for all the test results.
