BWwrote a review of Yakima Wheel Fork Tire Mount on June 25, 2009
I have to agree with Ekatalin, these tire mounts are not the most stable when mounted on round bars. That is because they always angle backwards no matter how tightly I screw the two clamps. This, in turn, causes them to rest against the roof of my car, which in and of itself isn't a very bad thing, but it does make me worry that a sudden and or sharp jolt will loosen the tire from the mount itself and cause my tire to go bouncing down some highway like Ekatalin's had done. So, I would recommend that anyone who purchases these tire mounts really tighten their quick release axle into/against the fork and that they check it as often as possible.
