Separate front and rear starting pressures for this ride. Offline on iPhone or iPad. Paid download, no account or ads. Get a separate front and rear starting pressure before you inflate. Add the rider, the bike, and the conditions for this ride. Bike Tire Pressure updates the two readings as you change them, in PSI, bar, or kPa. Use the result as a starting point, then follow the limits printed on your tire and rim. Set up the ride • Front and rear readings, shown together • Up to 8 bikes and 8 riders, stored on this device • Road, cyclocross, gravel, cross-country, trail, enduro, downhill, and fatbike styles • Dry or wet surface, with snow available for fatbikes • Close-up artwork for road, gravel, mountain, and city bikes • Advanced front and rear width, casing, inner rim width, rim construction, and wheel diameter • Kilograms or pounds, and English or Simplified Chinese Private and offline There is no account, ad, subscription, or network connection required. Rider, bike, and ride settings remain on the device. Before inflating Check the manufacturer's stated limits. Some tire and inner-rim combinations are marked incompatible instead of showing a number. A high-pressure notice uses this model's reference threshold for the tire width; it is not your rim's rating. The paid download is the complete app. There are no in-app purchases.
