| Spin Up Video | YouTube | YouTube |
| Rolling Resistance 90 PSI / 6 Bar |
15.8 Watts CRR: 0.00474 | 20.5 Watts CRR: 0.00615 |
| Rolling Resistance 75 PSI / 5 Bar |
16.7 Watts CRR: 0.00501 | 21.9 Watts CRR: 0.00656 |
| Rolling Resistance 60 PSI / 4 Bar |

| All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. |

Puncture Resistance Test Results
| Puncture Resistance Test Results (higher is better) | ||
|---|---|---|
| Model | Bon Jon Pass | Kojak |
| Puncture Resistance Tread | 8 Points | 12 Points |
| Puncture Resistance Side | 3 Points | 3 Points |
| Puncture Factor Tread* | 23 Points | 47 Points |
| Puncture Factor Side* | 2 Points | 2 Points |
| * Puncture Factor = Puncture Resistance * Total Tire Thickness. Puncture Factor provides a more realistic puncture resistance score for touring tires. |
