Wear Tracking

Wear Tracking helps you answer "is this car ready?" from the places you already use: the Garage, each car's Wear tab, the Parts inventory, and the track session log.

TrackOut can monitor tires, brake pads, and any part you choose to measure over time -- such as clutches, bushings, fluids, or other consumables with a numeric wear value.

Where wear status appears

The previous cross-car Wear destination has been replaced by these car-specific surfaces so wear decisions stay tied to the car, parts, and event you are working on.

Prep before a track day

When TrackOut sees an upcoming track day, it folds a Pre-event prep check into that event — on the Garage's Up Next list and the Events calendar. It checks the car assigned to that event and groups tires, brake pads, and wear-tracked parts by status.

• Blocked / critical items should be handled before the event.
• Attention / warning items are still usable but worth checking.
• Stale / unmeasured items need a newer reading before TrackOut can judge them confidently.
• Ready / OK items are currently above the configured wear threshold.

Cars with critical items open by default so the highest-risk work is visible first. If everything is unmeasured, the card prompts you to log tread depth and pad thickness instead of pretending the car is ready.

The parts wear banner uses the same safety-first language. Red items are safety-impacting, yellow items are worth watching, and grey stale-data prompts are visually quieter so they do not compete with real alerts.

The car Wear tab

Open a car and choose the Wear tab to review that car's consumable health.

The Wear tab can show:

• Tire tread depth history and current tread status
• Brake pad thickness history and current pad status
• Usage-based parts, such as parts with expected life
• Measured generic parts that you opted into wear tracking
• Cost-per-session summaries when enough purchase and usage data exists

Use Log first measurement or Log new measurement to record tread depth, pad thickness, or a part measurement without leaving the tab.

Wear Ledger

From the car Wear tab, click Open Wear Ledger to see every wear measurement for that car in one place. The ledger combines tire tread readings, brake pad events, and wear-tracked part readings into a timeline.

Each row can show:

• The part or tire being tracked
• Recent measurement history
• A sparkline for quick trend scanning
• An estimated sessions-remaining value when there is enough history

TrackOut needs several measurements before a projection is useful. If you only have one or two readings, use the ledger as history first and keep logging new measurements after sessions.

Wear Ledger on iOS

On iOS, open a car's Wear Ledger to see one timeline-style view across tires, brake pads, and wear-tracked parts. Each entry shows:

• The latest measurement and unit
• The configured floor or minimum value
• The number of readings TrackOut has stored
• An estimated sessions-remaining label when enough data exists

Use the ledger before an event to spot parts that are at the floor, close to the floor, or trending safely. It is most useful after you have logged multiple tread or part measurements over time.

Set up wear tracking for a part

You can opt a durable part into measured wear tracking from the part form.

1. Open Parts or a car's Parts & Consumables tab.
2. Add or edit a durable part.
3. Turn on Track wear over time.
4. Enter a starting value, unit, and optional minimum value.
5. Save the part.

Once enabled, the part appears in wear-aware places: the Parts inventory summary, inline part rows, the car Wear tab, pre-event prep checks, and eligible session logs.

Use any unit that makes sense for the part, such as mm, %, psi, or in.

Log part measurements

You can record part measurements from several workflows:

• Parts inventory row -- Click Log or Log first on a wear-tracked part.
• Car Wear tab -- Open the part row and log a new measurement from the measurement sheet.
• Track session log -- When the selected car has wear-tracked parts, the form shows a Parts check section so you can enter measurements while saving the session.

Measurements entered from a track session are linked to that session, so later analysis can connect part wear to the day and session where it was recorded.

On iOS, part detail pages can also enable wear tracking or log a measurement. If tracking is not configured yet, enter a fresh value, optional minimum floor, and unit. After tracking is configured, the same sheet switches to measurement capture with optional notes.

Reading the status

Wear status is intentionally descriptive:

Wear tracking is a planning aid. Always verify safety-critical parts manually before driving on track.
