Another newbie with another question. I have had same tires on my bike for about 3 years now. Just recently, I have been experiencing flats in my tires. I repaired the tubes and checked the tires for damage, but I couldn't find anything. I always check my psi and put air when necessary. If the tires are 'dunzo,' what would you guys and girls suggest for new tires? It's a road bike (a jamis satellite to be exact) and I'm just curious. Thanks for the input.
