How to verify this model year’s tires
Our 2023 Toyota Supra page has a battery observation, but no tire-size observation for this year. Open Toyota owner resources. Select the exact Toyota year and model. For a legacy Scion model, confirm manual availability or ask Toyota with the VIN. Find the manual’s wheels and tires section, then read the driver-door placard on the actual vehicle. The placard and installed wheels resolve options a general year/model table can miss.
- Record the front and rear tire notations separately, including P, LT or ZR, wheel diameter and any OE marking.
- Copy the load index, speed symbol and vehicle cold pressure. Tire-sidewall maximum pressure is a different value.
- Cross-check a manufacturer candidate in Goodyear’s vehicle finder only after selecting the actual trim and wheel package. Compare its result with the placard before using the placard-based tire check.
NHTSA tire safety guidance explains the vehicle label and replacement checks. No size on this page should be inferred from the battery row.
Before ordering tires
Read the driver-door tire placard. Match the installed wheel, axle, tire class, load index, speed rating and any OE marking. The size alone cannot approve a replacement SKU. Tire-sidewall maximum pressure is not your vehicle’s cold inflation pressure.

Toyota chart scope: These rows describe Toyota TrueStart replacement-battery applications, subject to the listed engine and option. They do not establish the factory-installed battery for an individual VIN or approve a third-party product.
Before ordering a battery
Check the actual battery position, chemistry, voltage, terminals, tray, hold-down, vent, CCA requirement and any BMS registration procedure. Group size alone does not approve a replacement SKU. High-voltage traction batteries are outside this guide.
What to verify next
- Match the exact year and factory options.
- Read the door placard and installed tire sidewall or the installed battery label.
- Compare an exact replacement SKU with the OEM requirements and ask a qualified installer when a condition remains unknown.
