In the November Issue: Tire Testing Quickly Shows How New Tires Outperform Old Ones

We didn’t simply install the new tires and drive around. 

We wanted to show how they compared to the old ones. 

While we realize this isn’t a strict apples-to-apples comparison, it demonstrates the difference between new tires and ones that look good but have aged out. 

Our testing focused on one simple metric: 60-to-zero braking. Data was captured via an Apex-Pro, an acquisition system that uses both GPS and inertia measurements.

Testing was done on two separate days, but the conditions were nearly identical: sunny, ambient temperatures in the 60s, and all on the same stretch of pavement. 

Before testing the Yokohamas, we put about 60 miles on them in order to remove any mold release compound. Our own J.G. Pasterjak handled the driving, and here we’ll let him take over for the rest of the story.
