Create the tire record at purchase, before packaging and receipts disappear. Record the vehicle, exact tire specification, each tire's identifier and position, installation date and mileage, seller, services performed, warranty documents, and the next inspection or rotation trigger.
Record the vehicle and specification
Write down the vehicle year, make, model, trim, vehicle identification number, odometer reading, and the recommended tire size and pressure from the owner's manual or door placard. Do not substitute the maximum pressure printed on the tire for the vehicle manufacturer's recommended cold pressure.
Record the installed brand, product line, full size and service description, load range when applicable, speed rating, and whether the tire is intended for a special season or use. NHTSA's TireWise guidance tells buyers to use the owner's manual or Tire and Loading Information Label for the correct size and pressure.
Identify every tire
Photograph and transcribe the DOT Tire Identification Number for each installed tire and the full-size spare. Note the wheel position at installation. The final four digits of the TIN identify the week and year of manufacture, according to NHTSA. Look on both sidewalls because the complete number may not appear on the outward-facing side.
Save the invoice, order confirmation, installation work order, and warranty booklet. Record the seller, location, purchase date, installation date, itemized tire price, installation services, taxes, disposal charges, and any road-hazard plan. Attach rebate or tire-registration confirmation when applicable.
Start the service log
Create one row for every inspection, pressure correction, rotation, balance, alignment, repair, or seasonal change. Include date, odometer, tire positions before and after, tread measurements, observed damage, pressure used, service provider, and invoice reference. Follow the vehicle and tire manufacturers' instructions rather than a generic interval. NHTSA advises checking the owner's manual for the correct rotation frequency and pattern because some vehicles should not use ordinary rotation patterns.
The record supports maintenance decisions and may also matter for a warranty claim. A Bridgestone limited-warranty document requires qualifying owners to furnish rotation evidence that shows date, mileage, and servicing location. Warranty terms differ by product and market, so keep the booklet that applies to the purchased tires.
Track condition and changes
At each review, record pressure when the tires are cold, tread depth at consistent points, irregular wear, cuts, cracks, bulges, vibration, and repeated pressure loss. NHTSA recommends recurring checks for pressure, treadwear, and damage, plus rotation, balancing, and alignment as appropriate. Have a qualified tire professional assess damage or performance changes.
When replacing one or more tires, close the old record with removal date, mileage, final position, reason, and disposition. Start a new record for the replacements instead of overwriting the old one. Keep receipts and service evidence together so tire age, location, maintenance, and warranty history can be reconstructed without guessing.
