Puncture Resistance Test Results
| Puncture Resistance Test Results (higher is better) | ||
|---|---|---|
| Model | Sport Contact II | E-Series Reach |
| Puncture Resistance Tread | 13 Points | 10 Points |
| Puncture Resistance Side | 5 Points | 6 Points |
| Puncture Factor Tread* | 55 Points | 44 Points |
| Puncture Factor Side* | 5 Points | 11 Points |
| * Puncture Factor = Puncture Resistance * Total Tire Thickness. Puncture Factor provides a more realistic puncture resistance score for touring tires. |
