Selecting Tires - Cannondale PROPHET Owner's Manual Supplement

selecting tires

Any properly installed and inflated tire must not contact any part of the swingarm, frame,
or fork and throughout full suspension travel.
The U.S. Consumer Product Safety Commission (CPSC) requires at least 1/16" (1.6 mm) tire
clearance from any part of the bike. Allowing for lateral rim flex and a wheel or rim that is
out-of-true will likely mean choosing a rear tire that provides even more clearance than the
CPSC recommends.
Also, your choice of replacement tires should be made only after considering the clearance
guidelines contained in suspension product owner's manual.
If the manufacturer's manual contains no such guidelines, or if you don't have a manual,
consider that Rock Shox requires at least 1/4" (5 mm) clearance between the tire and the
fork crown or bridge when the fork is completely compressed.
Be aware that completely compressing the fork may involve removing the spring stack,
letting the air out of the fork, or both.
WARNING
SELECT PROPERLY SIZED/ FITTED TIRES FOR YOUR BIKE.
Mounting the wrong size tires on your bike can increase the chances that you will have
an accident where you can be severely injured, paralyzed, or killed. If the tires touch the
frame or fork when riding, you can lose control of your bike. If a moving tire is stopped
because it touches the frame or fork, you can be thrown off the bike. You can be severely
injured or killed.
Do not mount oversized tires, ones that rub or touch the frame, ones that result in
too little clearance with the frame, or ones that can touch the frame or fork when the
suspension is fully compressed or when riding.
Take care that the tires you select are compatible with your bike's frame design. Also, be
sure to follow the manufacturer's recommendations of your front fork and rear shocks.
Ask your Cannondale Dealer for the right tires for your bike and its particular
components!
