Trying to figure out what tire to run for the rest of the summer?
Well deciding should get a little easier.
Project STR drivers Chris Harvey and John Rogers headed out to the Tire Rack test track to put our MX-5 through its paces, comparing six different 245/40R17 Extreme Performance Summer tires (five options are listed below while the sixth was the Toyo Proxes R1R) in dry and wet conditions.
Bridgestone Potenza RE-11
Dunlop Direzza Sport Z1 Star Spec
Hankook Ventus R-S3
Kumho Ecsta XS
Yokohama ADVAN Neova AD08
Results from the dry test will appear in the August issue of Grassroots Motorsports magazine, which hits newsstands in just a few days. Wet test details will be published in the following issue. And like many things we’ve discovered during this project, the results may not be quite what you expect.
