The tire range is limited and grouped together instead of individually being entered. ### 3/5 — Nice but could be so good *2020-06-12, version 1.1* I downloaded this app and liked the layout, problem is there is not enough tire widths included, would be great if this was added please ### 2/5 — Limited and confusing *2018-12-11, version 1.1* This might be a decent app, but out of the gate it has two glaring issues for me: 1. It only deals in weight by pounds (lb). I deal in kilos! There doesn’t seem to be any way to change your preference 2. More advanced calculations are available, but they’re a bit hidden away. You have to swipe left or right to page between them, which took me a while to discover ### 1/5 — Pointless! *2017-04-25* 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!!!! ### 1/5 — Meh. Useless. *2016-09-27* 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. ### 1/5 — Inaccurate *2016-09-27* Not useful. Gives pressure rec of 216 psi for rider and bike of 195 lbs. ### 1/5 — Good only if you don't need it! *2016-09-24* 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! ### 3/5 — Maybe I am missing something *2016-09-22* 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. ## Frequently asked questions about Prestacycle Bicycle Tire Pressure Calculator ### What factors does Prestacycle use to calculate tire pressure?
