Road bike tires are made for all levels of riders. There are puncture-resistant tires, which are great for general bike training and for commuting to and from work. Then there are lightweight, thin casing road tires which are best suited for bicycle racing conditions. So what are some of the big things to look for in road tires? The first is, does the road tire fold up into a foldable tire, or is it a beaded tire, in which case it always stays in its full round shape. Foldable road tires cost more, as there is more difficulty in manufacturing them. They also tend to be lighter in weight that regular tires. The bead is the edge of a road tire. On most road bike tires, the bead consists of hoops of strong steel cable, but can also be other metal as well. The beads are what hold your tire onto the bike rim, interfacing with the rim wall to create a tight fit.. While most bike tire beads are steel based, some road tires use Kevlar cord in place. The second thing is, the thread count for a road tire plays a big part in the comfort level and price point for the tire. A 200 thread count tire might be considered a recreational tire, good for training and for all-purpose bike riding. If you puncture or otherwise damage a low thread count road tire beyond repair, you'll be glad you saved money buying it. Getting a slash in a brand new, 320 thread count road tire in the first 10 miles of riding can be a painful experience to the wallet! Clincher tires are used on 99% of all bicycles now, and they are also called "wire-on." You've got the bicycle tire, and then a separate inner tube. The edges of the tire hook inside the rim edges, and the inner tube air pressure pushed outward to create a tight interface between road bike tire bead and rim wall. You may suppose that bike tires are made of rubber because that is what you see as the rolling surface. It turns out, rubber is one of three components that make up a tire, and arguably is the important in terms of tire structural integrity. There is cloth fabric woven between the two beads of any road tire to form the body of a tire. Most road bike tires use nylon cord, though some may use other polyamides. The fabric threads don't interweave, as you'd think, with the crossing threads - that's how it is with normal cloth. Instead, the threads are arranged for road tires in layers or "plies" of parallel threads. By using thin thread, there are more threads per inch ("TPI") - as mentioned before, TPI relates to bike ride comfort and to bike tire pricing. The higher is TPI number, the thinner and hence more flexible will be the bicycle tire fabric. High TPI bike tires will generally be lighter weight, and likely have lower rolling resistance. But such road tires are often more easily damaged by road hazards. Once the bike tire fabric is woven between the beads, the tire will have its basic shape. Now, the bike tire is coated with rubber. The rubber is there primarily to protect the fabric from damage! That's right, it has no structural importance for the overall road bike tire. A frequent debate among cyclists is whether a wider road bike tire has more or less rolling resistance at a given pressure. Recent conventional wisdom calls for inflating bike tires to various PSI depending on rider weight. So for example, a 150 lb. rider may inflate a max 120 PSI rated road bike tire to just 112 lbs. in order to get the optimal rolling resistance. Why? Because a tire is supposed to deflect off the riding surface a bit under load. This deflection of pneumatic tires is what makes them comfortable to ride, as compared say to a solid rubber tire. A properly inflated bicycle tire should bulge a bit when you sit on your bike. Bet you didn't know there was so much more than rubber that makes up good road tires!
