The MTB section is a multi tire size section, air pressures have been adjusted to the measured casing width. 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.

NOTE: As of 2021, we've improved the puncture resistance tests and now provide 'Total Puncture Score' as the main puncture resistance indicator. Total Puncture Score: This score consists of Puncture Force Sharp Needle, Puncture Force Blunt Needle, and Total Tire Thickness. This value will give the best indication of real-life puncture resistance. Puncture Force Sharp Needle: Pre-2021, this score was known as 'Puncture Resistance'. On some tires with weakly bonded casing wires, the sharp needle can split the casing wires resulting in a lower score. Puncture Force Blunt Needle: The Blunt needle has a flat tip and won't split the casing wires. To puncture the tire, the blunt needle has to cut the casing wires. Total Tire Thickness: The puncture force tests are static and test the force required to puncture the casing and anti-puncture layers. To convert from a static lab test value to a more dynamic puncture resistance score, the thickness is used to calculate the total puncture resistance. More Info Close

Static Grip Test Results

Static Wet Grip Test and Off-Road Tires

It's critical to understand our static wet grip test works with a hard surface. This means the grip data is only directly useful for comparing tires on hard surfaces where the rubber compound creates the grip. Understanding the test results gets more difficult when grip is created by the knobs digging into the surface.

On soft surfaces (loose sand, grass, etc), almost all grip will be created by the knobs digging into the surface, and our test results will be of little use.

There will also be many surfaces where the total grip will be a combination of the tread compound grip and the grip provided by the knobs. Under these circumstances, the hard surface grip can still be a deciding factor.

Given these shortcomings, we feel our grip test, combined with the knob height measurements, will still be valuable information when comparing tires.

For more about our grip test, and how the knobby tread pattern affects the test results, we have more information here.
