For tires that have failed the Giant test protocol, we are working with the tire brands so updates can be made to make them ready for our hookless rims as soon as possible.
Please be aware that if you choose to use a tire with an indicated maximum pressure above 72.5psi (5 bar) that is not on the list of tires that have passed the Giant test protocol, YOU DO SO AT YOUR OWN RISK, as the tire may not function properly with the Giant hookless WheelSystem.
Please note that if the maximum pressure indicated on the sidewall of a tire is below 72.5psi (5 bar), the tire is tubeless compatible, and is not indicated as being incompatible with hookless rims, it can be used with Giant hookless WheelSystems and does not have to appear on the ¨What Tires Can I Use" chart:
Although Giant tires are designed for best use with a Giant hookless rim, it is possible to use a Giant tire on a hooked bead rim.
If necessary, you may use an inner tube on a Giant hookless rim, so long as the tire you are using has passed the Giant test protocol. However, please note that Giant hookless rims are designed to perform best when set up as tubeless and used without an inner tube.
Please review the test protocol for a detailed explanation of the testing for tires on Giant hookless rims, as well as for more information on the test results of the individual tires themselves.
