Fleet Tire History Log Template by Tire Position

A tire that is logged by vehicle only tells you that something happened somewhere on the truck. A tire logged by position tells you where, when, and under which conditions, which is what you need to find alignment drift, pressure loss, and mismatched duals. This page gives you a position coding scheme, a log template you can copy, and checklists for fitting, inspecting, rotating, and removing tires. It also shows how Oxmaint fleet maintenance software can hold the same record digitally, so the history follows each tire and each wheel position.

Fleet Tire History Log Template by Tire Position

Give every wheel position a code, every tire a record, and every event a date. The log below works on paper or in a maintenance system.

Axle 1 steer1L1R

Axle 2 drive2LO2LI2RI2RO

Axle 3 drive3LO3LI3RI3RO

Axle number, then side (L or R), then O for outer or I for inner on duals. Trailers can use a T prefix, such as T1LO.

Why log tires by position

Wear and failure depend on where a tire sits. Steer, drive, and trailer positions carry different loads and fail in different ways.

Steer tires show alignment and suspension problems first and carry the highest safety stakes.
Inner duals run hotter and are harder to inspect, so pressure loss often goes unseen there.
Trailer tires are easy to overlook, even though they can account for many roadside tire findings.
Repeated damage on one position points to a vehicle or route cause, not a bad tire.
A rotation record shows whether a tire has moved from steer to drive to trailer.

Step 1: Adopt one position code

Any consistent scheme works. What matters is that every depot, technician, and report uses the same one.

Code part	Meaning	Example
Prefix	Unit type: blank for the tractor or truck, T for trailer	T2LO is trailer, axle 2, left, outer
Axle number	Counted from the front of the unit	1 is the steer axle
Side	L for left, R for right, looking forward	2R is right side of axle 2
Dual position	O for outer, I for inner	3LI is axle 3, left, inner
Spare	SP with a number	SP1

Print the code chart and keep it in the shop and in each vehicle's inspection checklist.
Always state the viewing direction, so left and right are never confused.

Step 2: The master record for each tire

Create one record when a tire enters service. It stays with the tire as it moves between positions and vehicles.

Tire IDSerial or DOT code, plus your own asset number

Brand, model, sizeIncluding load range and intended position

New, used, or retreadWith the casing history if known

Purchase detailsSupplier, date, and cost

Starting tread depthMeasured at fit, in 32nds or millimeters

Manufacture dateRead from the DOT code to track tire age

Fitted toVehicle, position code, and odometer

Target pressureCold pressure for that position and load

Keep every tire record in one system

Store positions, readings, and events against each vehicle, and let scheduled inspections prompt the next entry.

Step 3: The position log template

Copy this layout to a spreadsheet or print it. Add one row per position per inspection or event. The rows shown are examples only.

Date	Vehicle	Position	Tire ID	Odometer	Cold pressure	Tread outer / center / inner	Condition	Action	Tech
Example	Unit 118	1L	Tire A	Reading	Reading	Reading x3	Even wear	None	Initials
Example	Unit 118	2LO	Tire B	Reading	Reading	Reading x3	Shoulder wear	Alignment request	Initials
Example	Unit 118	2LI	Tire C	Reading	Reading	Reading x3	Low pressure	Inflate and leak check	Initials

Event codes to use in the Action column

FIT for a new, used, or retread tire fitted to a position.
ROT for rotation, with the old and new position recorded.
REP for a repair, with the type and location of the damage.
REM for removal, with a removal reason and final tread depth.

Checklist: fitting a tire

Complete these at every mount so the record starts clean.

Confirm tire size, load range, and type suit the position and axle.
Match the tire with the other tire in a dual pair by size and tread depth.
Check the casing and valve for damage before mounting.
Record tire ID, manufacture date, and starting tread depth.
Inflate to the target cold pressure and record it.
Torque wheel fasteners to specification and plan a re-check after a short distance.
Enter the position code and odometer in the log.
Sign and date the entry.

Checklist: every inspection visit

Split the work between the quick walkaround and the full measured check.

Walkaround (each trip or day)

Look at every position for low, bulging, or damaged tires.
Check valve caps and look for air leaks or fluid on wheels.
Check wheel fasteners for loose or missing items.
Report any pull, vibration, or noise.

Measured check (at PM)

Cold pressure at every position, including inner duals and spares.
Tread depth in a major groove, at several points across the tread.
Wear pattern noted and compared with the last entry.
Sidewall, bead, and casing condition.
Dual match check by diameter and pressure.
Brake and wheel-end condition where wear suggests a link.

Regulatory reference

In the United States, 49 CFR 393.75 sets minimum tread depths of 4/32 inch for steer tires and 2/32 inch for other positions on commercial vehicles.
Confirm the current rules for your country, vehicle class, and operation, and set your own replacement points ahead of the legal minimum.

Checklist: rotating and moving tires

Moves between positions change a tire's duty. Record each one so the history stays correct.

Record the old positionWrite the code and the last readings before removal
Check suitabilityConfirm the tire type and tread suit the new position
Re-match dualsPair by diameter and tread depth, not by habit
Set pressureUse the target for the new position and load
Log the moveAdd the new code, odometer, date, and initials

Checklist: removing a tire

The removal entry is the most valuable line in the log. It explains why the tire ended its time on that position.

Worn outRecord final tread depth and miles. Mark the casing for retread review.

Irregular wearRecord the pattern and raise a work order for the likely cause.

Damage or road hazardRecord the location and cause. Note any repairs made before.

Air loss or repeat repairsRecord leak points and check the wheel and valve.

Age or casing conditionRecord manufacture date and inspection findings.

Early failureRecord supplier details and hold the tire for a warranty claim if applicable.

Reading the log: patterns by position

Once entries build up, the history points to causes. Use the patterns below as prompts, then confirm with an inspection.

Pattern in the log	What it suggests	Follow-up
Same steer position wears faster than its twin	Alignment or suspension fault on that side	Alignment check and component inspection
Inner dual always lower in pressure	Hard to reach, or a valve or wheel leak	Leak test and valve extension check
Repeated damage on one position	Route hazard or a wheel-end problem	Review route and inspect the position
One dual tire worn faster than its pair	Mismatch or pressure difference	Re-match and correct pressure
Trailer tires removed early across many trailers	Weak trailer inspection routine	Add trailer positions to the inspection plan
Missing entries for several weeks	Inspection compliance gap	Review PM schedule and responsibility

Paper log versus digital tire record

Paper works for a few vehicles. Digital records scale better when positions, duals, and trailers multiply.

Paper or spreadsheet

Easy to start with no setup
Entries can be late, illegible, or missing
Hard to see trends across many vehicles
No automatic prompt when a check is due

Maintenance system record

Readings captured at the vehicle on a phone
History follows the tire and the position
Checks scheduled by date, mileage, or hours
Reports show wear, cost, and repeat issues

KPIs to pull from the log

A well-kept log supports a small set of useful measures.

Tire history log FAQs

Why keep tire records by position and not just by vehicle?

Wear and damage depend on the position. A position record links problems to alignment, load, or route causes.

What should be on every tire log entry?

Date, vehicle, position, tire ID, odometer, cold pressure, tread depth, condition, action, and the technician's initials.

How often should tires be measured?

Set the interval from your duty cycle, tire supplier guidance, and local rules. Many fleets measure at every PM and watch tires near their limits more often.
