I have read many reviews on these tires and I finally decided to get a pair. Most of the negative reviews were around installing the tire and how hard it was. I didn't realize how bad it was going to be to install the tires on the rims. I even bought the $20 tool to help. I am glad I did. It was the only way I was able to get the plastic pieces to clip into the rim. I spent an hour plus on each tire installing them. If Tannus could come up with a solution to install the tires in an easier fashion I would definitely recommend them, but as for a time saver so I don't have to worry about flats, I'm not sure this qualified. I can change a flat tire in less than 15 mins. With over 3 hours of install time I could have replaced over 12 flat tires. Not convinced that they are worth the work of getting them on the bike.
