Bicycle Tire Pressure Calc
Find the best tire pressure for your bike. It may not be what you think.
The Bicycle Tire Pressure Calculator is used to compute the optimal air pressure for your bicycle tires. Tires pumped too hard bounce down the road like a basketball, wasting energy. Tires pumped not hard enough are sluggish and prone to pinch flats. Tires pumped just right are at the optimal intersection of responsiveness, shock absorption, and energy efficiency.Popular misconception is to pump a bikes tires to the highest number printed on the sidewall by the manufacturer. Instead, the optimal pressure is that which yields in a 15% sidewall drop. Sidewall drop is a non-linear function of the load on the tire and its width. It can be computed based on the weight of the bike, rider, bags, and gear. It is also different between front and back, depending on the frame geometry.With this App, you can instantly compute the optimal tire pressure from your phone or tablet wherever you may be: in your garage, on the road, at a friends house.Features:* Enter weights in either pounds or kilograms* Calculate pressures in either PSI or bar* Tire widths from 19 to 60 mm; diameters of 26", 650B, and 700C; 4 of the most typical frame geometries or user-defined measurements* Configure and save multiple bikes* Tap bike graphic to recalculate pressuresUpdated for more device compatibility.

Having used this app for a number of years, on both off-road expedition bikes and road tourers, it always gives pressure values that will give a comfortable ride with no pinch flats
it was ok until it began "forgetting" the bikes I added to the list. Tire pressures are unbelievably low until I've ridden with them.
No bike in my household fits any of the generic categories, so I am very happy to be able to work with the "custom." I LOVE not overinflating my tires, and having a far better chance of staying upright on rain-slick roads. I'm grateful for far less rattling of teeth. Everyone I've tried to market this to is an iPhone user, so I hope you write a version for them, too. (And it makes me happy that you're local.)
Very good app, improved the ride quality on my roadbike. But no provision for MTB offroad bikes. Five stars when this is included.
Very easy to use and configurable, love it!
Looking for Hybrid and MTB Would be nice. For now I'm trying to figure out which of the existing ones are close enough that I could use them instead. They based on the front to rear weight ratio by any chance?
Seems like a great app. Minus one star since the Android Menu isn't working (at least not on my OnePlus Two) and so I cannot switch to metric units.
Excellent, good range and serves me well. A couple more profiles I.e. hybrid, etc would be helpful but overall very nice.
by using custom the calcs run within one psi f/r of Heine or the Bike Tinker spreadsheet.
Works great, no guess work, where is the mtb selection?
