![]() ![]() When we look at the suggested Racing Ralph/Racing Ray front/rear pairing, we see there aren't that big of differences between these tires. At higher air pressures the Racing Ray is slightly faster because of the center blocks being closer together. We do see a difference between high and low air pressures with the Rocket Ron being slightly faster at lower air pressures because of its more open tread pattern. When we compare the Racing Ray to the Rocket Ron with the same casing and compound, both tires perform very close to each other in our tests. Grip in points = coefficient of friction * 100 Given these shortcomings, we feel our grip test, combined with the knob height measurements, will still be valuable information when comparing tires.įor more about our grip test, and how the knobby tread pattern affects the test results, we have more information here. ![]() Under these circumstances, the hard surface grip can still be a deciding factor. 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. ![]() 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. Understanding the test results gets more difficult when grip is created by the knobs digging into the surface. This means the grip data is only directly useful for comparing tires on hard surfaces where the rubber compound creates the grip. It's critical to understand our static wet grip test works with a hard surface. 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. 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.
