Have you ever found yourself cruising Instagram late at night wondering, lusting after someone’s bike build, and wondering… “what tires?” Well, you’re not alone. We all do it.

And lucky for us, the folks behind WhatBars.com have now put together What Tires? The Bicycle Tire Database. Since launching WhatBars.com, they’ve had a lot of requests for a similar resource for tires, and couldn’t help but give the people what they wanted.

Sim Works and Crust Bikes jumped on board to help support the project, and here we are. The database is still being built out, but you’ll find tires from Sim Works, Rene Herse, and WTB up on the site. Head over to What Tires to compare and keep the rubber side up!
