I rode Gator Skins (similar idea to Armadillo) for 3,000+ miles and only had one flat on the road. It was a pinch flat do to low tire pressure, my own darn fault. My husband did not have as good of luck with them. I would still recommed them over the soft tires that are going to come on a Ruby and plan to spend $30-45 per tire.
