![]() Total Tire Thickness: The puncture force tests are static and test the force required to puncture the casing and anti-puncture layers. To puncture the tire, the blunt needle has to cut the casing wires. ![]() Puncture Force Blunt Needle: The Blunt needle has a flat tip and won't split the casing wires. On some tires with weakly bonded casing wires, the sharp needle can split the casing wires resulting in a lower score. Puncture Force Sharp Needle: Pre-2021, this score was known as 'Puncture Resistance'. This value will give the best indication of real-life puncture resistance. ![]() Total Puncture Score: This score consists of Puncture Force Sharp Needle, Puncture Force Blunt Needle, and Total Tire Thickness. NOTE: As of 2021, we've improved the puncture resistance tests and now provide 'Total Puncture Score' as the main puncture resistance indicator. Puncture Resistance Test Results Puncture Resistance Test Results (higher is better) Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. The Road Bike section is a multi tire size section, air pressures have been adjusted to the measured casing width.Īll numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Test Results Size, Weight, and Thickness MeasurementsĪll size measurements are taken at an air pressure of 100 psi / 6.9 bars on a 17.8 mm inner width rim.Ģ8-29 = 108 psi/7.4 barUltra High Air PressureĢ8-29 = 90 psi/6.2 barExtra High Air PressureĢ8-29 = 54 psi/3.7 barMedium Air Pressure Page to read in detail about how we test bicycle tires.ĭon't forget to take a look at the overview pages to make it easier to compare all bicycle tires that have been tested: Read on to find out more about how this tire performs in our tests.Īll rolling resistance tests are performed on our rolling resistance test machine. If you're looking for one of the fastest road bike tires out there, the Power Time Trial definitely should be on your list. This compound change probably shaved another bit of rolling resistance off the total rolling resistance. The rubber compound also received an update and is now called the "Race-2 compound" while the Power Competition uses the "Race compound". This is achieved by omitting the anti-puncture strip and also applying a thinner layer of rubber to the tire. ![]() The main difference between the Power Time Trial and Power Competition is that the Power Time Trial is thinner, lighter, and less puncture resistant. The Power Time Trial looks very similar to the Power Competition ( read our review) that has been available since 2016 as both use the same 3x180 TPI casing. Puncture resistance and durability aren't the most important design criteria for a tire like the Power Time Trial. ![]() This means the Power Time Trial was built for speed first and foremost. As the name suggests, the Michelin Power Time Trial serves only one purpose: shaving those last few seconds off the clock to gain an edge on the competition. ![]()
