I ride up and down Hwy A1A in Florida and, flats are a constant problem. Drunk rednecks chunk glass bottles out of their car windows and construction debris is everywhere. I've had some pretty bad spills. The last time my front tire blew out I flipped completely over and landed on my back! Anyhow, I've had some success with Michelin Pro Tek tires. Kenda Armor Shield tires. Various thorn proof tubes. Slime. And, on my race bike: Continental Gatorskins. It sucks that I can't enjoy riding on some really sweet fast tires. But, that's life on A1A.
