Are there currently any airless tires that fit Bike Friday? I have a 1997 New World Tourist and am interested in replacing my current tires with these.
There are a limited selection of airless tires available for Bike Friday wheel sizes. Your New World Tourist uses 406mm bead diameter rims. A Pocket Rocket would use 451mm diameter rims. The most respected name in airless tires is an English company called Greentyre. Check out their website at www.greentyre.com. I believe you can order direct from them.
The airless tires are nice in that they don't go flat, however, they do tend to compromise performance.
If you are concerned with performance, you may want to try a pair of Kevlar-belted conventional tires. We offer two Kevlar-belted tires in the 406 bead diameter.
