Did you know that some bicycle tire brands such as Continental have tire wear indicators so that you can more easily tell when your tire is worn out and needs to be replaced?
See those two divots in the tire above? Those aren’t gouges from running over something sharp. Those are the tire wear indicators. This tire only has a few hundred miles on it and it still fairly new.
Here’s a view from further away. On Continental tires, you’ll probably find the wear indicator marks near where the tire name is printed.
When you no longer see those holes, it means that the tire has worn down to the point that it needs to be replaced. No guessing required!
Here’s Continental’s page about it, which also tells you which specific tires have the wear indicator divots. https://continentaltire.custhelp.com/app/answers/detail/a_id/896/~/bicycle-tire-treadwear-indicator
Here’s how the tire wear indicators work with Schwalbe tires: https://www.schwalbetires.com/technology-faq/tire-wear/
Are there other major bike tire brands that have wear indicators that we left out?
