Prestacycle Bicycle Tire Pressure Calculator Reviews

Need more choices.

The app is fairly neat. What it lacks is the ability to choose rim size and tire size. I ride plus and fat bikes. This app can't help me until the tire and rim selection is increased and/or made manual. It has the potential to be a cool tool.

Maybe I am missing something

Sample problem: plug in rider + bike weight = 205lb. Suggest 45/55 split between front and back, but results are 106.79 for both. And, the pressures all seem a bit high, for example, when compared with Schwalbe's recommendations.

Good only if you don't need it!

Only works for small people and skinny tires. If you are a bike racer, why bother? You already have a team mechanic to figure out your tire pressure!

Inaccurate

Not useful. Gives pressure rec of 216 psi for rider and bike of 195 lbs.

Meh. Useless.

Largest tire is 32, doesn't account for tubeless, tire TPI, road surface. Get an accurate gauge and a China marker, try different pressures, write them on the tire sidewall. Use the one you like best.

Pointless!

This app results are whacked out. Tells me 102 psi for 190 lb rider, and 195 psi for 210 lb rider and bike. Stupid app!!!!
