Sure thing, Jerry! I like the GoCruise because it's really easy to put on and take off. The price is right, too. Here's a picture of the rear tire on the hawk:
The angle isn't great, but the knobs in the center are really worn down. I'm not terribly concerned about it. Like I said before, I can order a full set of tires for the Hawk and not spend enough money to get free shipping.
I guess that just means I'll need to put an extra set of tires for the DR on the shelf, too. Actually, I think the front tire on the Rebel is in desperate need of replacing...
