THE CADEX
TIRE TEST PROTOCOL
If the maximum pressure indicated on the sidewall of the tire is above 72.5psi (5 bar) and the tire is hookless rim compatible as per the tire manufacturer’s recommendation, then the tire enters into the CADEX test protocol. This will ensure it functions properly with CADEX Hookless
WheelSystems. If the tire passes the protocol it will be listed on the “WHAT TIRES CAN I USE?” chart.
The CADEX test protocol consists of two tests:
HIGH-PRESSURE TOLERANCE TEST
First, the tire is inflated to 72.5 psi (5 bar), an average minimum pressure for most riders on 25c tires, and must withstand this pressure for 24 hours without blowing off. Next, the tire is inflated to its recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. After that, the tire is inflated to 1.2 times the recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. Finally, the tire is inflated to 1.5 times the recommended maximum pressure and must withstand this pressure for 24 hours without blowing off. The final number of 1.5 times the recommended maximum pressure is intended to simulate such extreme conditions as hitting a square edge or a pothole at high speed causing the tire pressure to increase suddenly. If the tire has been able to withstand the four pressures for 24 hours respectively without blowing off, it passes the CADEX high-pressure tolerance test.
For your own safety, please do not inflate the tire over the recommended maximum pressure or attempt to replicate this test.
HIGH-PRESSURE BRAKING TEST
The tire is inflated to 1.2 times the recommended maximum pressure, mounted on a disc brake wheel, and must withstand braking forces without blowing off or experiencing a shift in the position of more than 3mm. This test is used to simulate accidental high-speed uncontrolled braking causing excessive friction between road and tire and possible movement of the tire on the rim resulting in blow-off.
For your own safety, please do not inflate the tire over the recommended maximum pressure or attempt to replicate this test.
NOTE: If the maximum pressure indicated on the sidewall of the tire is below 72.5psi (5 bar) and the tire is hookless rim compatible as per the tire manufacturer’s recommendation, the tire can be used with CADEX hookless WheelSystems and does not have to appear on the “WHAT
TIRES CAN I USE?” chart.

For your own safety, never inflate tires over the recommended maximum pressure or attempt to replicate tests.
All tests are performed on the samples received from the respective tire brands. Because tolerances among mass-produced tires can vary, test results cannot 100% represent the results of all production tires.
Test results only show the outcome of the CADEX tests, they do not reflect the tire’s performance or quality.
