TPCalc

TPCalc makes it easy to set up your bike tires with the right pressure. Just enter your weight, bike weight, and tire size, and the app calculates recommended front and rear pressures. The app adjusts results based on bike type and weight distribution, helping you get the right balance of comfort, grip, and rolling efficiency. Whether you ride road, gravel, mountain, or touring bikes, TPCalc takes the guesswork out of tire setup and makes every ride smoother. TPCalc is free and ad-free for everyone. Three optional support purchases let you contribute to continued development. Each support purchase is a one-time consumable payment that can be repeated; it does not unlock features or start a subscription.
