TireWise: Pressure & Tread

Keep your tires safe with a log that actually tells you something.

TireWise records the pressure and tread on all four corners, compares each reading to your door jamb target, and shows exactly which tire is low and how much to add. Enter the numbers off your gauge in seconds and the app does the thinking.

WHAT IT DOES

• Four corner pressure log: every check stores front left, front right, rear left and rear right, with a clear on target, add air, or over reading against your cold target.
• Tread depth log: record tread in 32nds of an inch or in millimetres, with the 2/32" legal minimum marked.
• Cold vs warm adjuster: air pressure falls as it cools, about one psi for every 10 degrees Fahrenheit. Enter a measured pressure and two temperatures and see the true cold value, so a warm reading never fools you.
• Cold morning forecast: see the pressure to expect on a chilly morning and how much to add to stay on target.
• Door jamb targets per axle: set the front and rear cold targets once and every check is judged against them.
• Metric or imperial throughout: psi, kPa or bar, 32nds or millimetres, Celsius or Fahrenheit.

TREAD WEAR TRENDS (PRO) Watch tread step down over time on a clean chart, with a life estimate in months and kilometres from your own wear rate, and a warning as any tire nears the legal minimum.

ROTATION REMINDER (PRO) Turn on a gentle, time based nudge to rotate and check, on the interval you choose. Tire rotation is usually every 8,000 to 13,000 km.

MORE VEHICLES (PRO) The free app tracks one vehicle. Pro adds every car, truck and trailer you own, each with its own targets and history.

EXPORT (PRO) Export a one page PDF log summary for your records or a mechanic, and a CSV of every check, straight from the share sheet.

FREE AND PRO The single vehicle log, the cold vs warm adjuster and the cold morning forecast are free, forever. The one time Pro unlock adds tread trends, the rotation reminder, more vehicles and export. There is no subscription: pay once and keep it.

PRIVATE BY DESIGN No account, no cloud, no tracking. Every reading stays on your iPhone.

TireWise is an informational log, not a tire pressure monitoring system or a safety inspection. Always set pressures cold, follow your vehicle's door jamb placard and owner's manual, and have a professional check any tire that keeps losing air.
