Here's an interesting test that Motor Trend magazine did. They compared a Bolt with standard, low friction tires and then swapped out to Ultra High Performance tires. As expected, the handling and braking improved measurably, but the range and efficiency dropped dramatically. They commissioned an independent test lab to confirm and found that range decreases from 244 miles (better than EPA 238) to 178 miles, and efficiency drops from 122 to 89 mpge
