Its easier to ask forgiveness than permission, so Ive heard. I have had no problems so far after several thousand miles and I encounter police cars as often as anyone else. I thought of making the roller with hinge at the top also, too complicated, as the hinge needs to be straight and the fender is curved. The roller also sticks out. Actually only about and inch of clearance is necessary, contact is made only on turns. A curve in the road requires less than an inch of steering. The key is the wheel center foam block that spaces the skirt away from the tire, and does so with almost no friction.

: Saturn wheel base is 102 inches. Tires are 205/70R15 with and OD of 26 inches. arcosine of 1/13 is 85 degrees, so the steering is turned 5 degrees before start of contact. I notice the contact when making 3 point turns and parking mostly, and when exiting the driveway.

As for damaging the tire, I have seen none. The initial contact is very light. I think the HDPE sheet would wear through first, but I haven't seen any wear yet, it's slippery stuff. I sprayed Areodag graphite on the inside when I put them on, but this is long gone now.

Sorry for hijacking the thread.
