Bike Road Tyre


How many miles should I put on a road bike tire before replacing?

As everyone else said, it depends on the tire itself, but I’m going to explain the criteria.

3 things really determine the lifespan of a tire:

1. Thread per inch (TPI). The higher your TPI, the shorter the tire will last. The body of the actual tire is woven cloth and not just rubber. The thinner the threads of the cloth, then the more you can fit into an inch, so a high TPI means thin threads. A good range is around between 50 and 75 TPI for your average cyclist. Higher TPIs over better grip, traction, and control but don’t last long on the road and are better suited for racing or a track. A 120 TPI tire might have a few hundred miles and a 50 TPI might have a couple of thousand miles.

2. Rubber. The actual rubber that makes up your tire also determines the lifespan. Softer rubbers offer great traction, but they wear out much much faster. Unfortunately aside from feel, there’s no real hardness level spec that tire manufacturers disclose to consumers.

3. Tread pattern. The knobbier your tire, the longer it’ll take for your tire’s tread to actually wear down. The smoother your tire, the faster the wear which is also a surface area problem, but the benefits of a smooth tire on the road far outweigh this inconvenience.

If you can post the name of your tire, it’ll be much easier to figure out.
