What this car's tires have measured

Open a car, choose History, and find the Tires section. It gathers what its wheels have measured, visit by visit, newest first. Nothing is recorded or edited here: every number is the technician's own, taken on an inspection sheet for that visit and read back in one place.

Above the table, one sentence answers the question most people open the section with — when the tires were last looked at, on which order, at what odometer, and which corner is shallowest right now: Left front is shallowest at 4/32 in.

Reading the grid

Each row is one visit. Measured is the day the sheet was started, which is the day the car was in front of the technician; a sheet still being worked carries in progress beside the date, because a partial reading is still a reading. Order links to the ticket it was taken on.

Mileage is the odometer on that ticket — what it left on, or what it came in on where it has not left yet — and never the car's reading today. That is what makes the column answer how worn the tires were at that mileage rather than at this morning's.

After those three comes one column per wheel, named the way the sheet names it — Left front, Right rear inner, Spare and the rest. Each cell reads the way the technician's own sheet reads it: 6/32 in · 32 psi, tread first, and only the readings that were actually taken.

The columns come from the readings rather than from a wheel layout. A car inspected as four corners last spring and as four plus the spare today gets five columns, and the spring visit says not measured under the spare — which is what happened.

Read across a row for the car at one visit, which is the comparison a rotation recommendation comes out of. Read down a column for one corner over time.

Not measured is not zero

A corner nobody put a gauge on says not measured in words rather than showing a dash or a blank. That is deliberate: a dash under a tread column is read as a zero by somebody scanning quickly, and a tire at 0/32 is a tire being replaced today. Torqix will not invent that number, and it will not let the shape of an empty cell imply it.

A whole visit whose wheel boxes nobody filled in is not drawn at all, rather than appearing as a dated row of dashes. Where two lines on one sheet both measured the same corner, their readings are shown in one cell, and where both carry the same kind of reading the first one in the sheet's own order is the one that shows.

How readings get here

They arrive from an inspection whose template checks each wheel. When a technician works that sheet in the bay, the tread and pressure they gauge at each corner land here, dated, on the visit they were taken. A car whose inspections have never asked for a per-wheel reading has an empty Tires section, and the section says so rather than offering a button — the door to a reading is the ticket, not the car's record.

To jot down pressure without an inspection, open the order, press the car at the top right, and fill the four PSI boxes, or use Add PSI on the order's Vehicle tab. Those four numbers belong to that order. Where the order has none, the boxes show the last inspection's reading in grey.

Demo and sample data is left out of a live shop's History, the same as everywhere else, and another shop's car is simply not there.
