Why the catalogue result was held
The 2025 Mini Convertible tire candidate was withheld: No exact model-year source table was returned: http_error No independent low-voltage battery application was established.
Review log: The attempted 2025 catalogue address returned HTTP 404. A missing web page is not evidence that the vehicle lacks tire or battery specifications. Use the owner manual and the vehicle labels instead.
Mini Convertible research focus: Select the Convertible manual and its actual wheel option rather than using a hatchback or Clubman result.
Find the tire specification
Open MINI owner resources. Use the VIN or model-year selector; MINI also provides a legacy-manual archive. Select your actual model year and read its wheels and tires section. Then compare the driver-door placard with the installed front and rear tires. NHTSA tire safety guidance explains why the vehicle placard matters.
- Copy the complete tire notation, including its P, LT or ZR prefix where present, and the wheel diameter.
- Record each axle separately, plus load index, speed symbol, OE marking and vehicle cold pressure.
- Use Goodyear’s model-year finder as a second source only. If its trim or axle options disagree with the placard, stop and use the vehicle maker’s instructions.
Find the 12V battery specification
Use the exact VIN and powertrain with the manufacturer’s parts or service desk. Ask for the current low-voltage replacement part, its technology and any superseded part numbers. The owner manual may describe replacement steps without giving a BCI group.
- Photograph the installed battery label and its location. Note voltage, group or OEM case code, AGM/EFB/flooded technology and CCA if shown.
- Confirm terminals, hold-down, tray, venting and any battery-management registration with current OEM service instructions.
- Use Interstate’s battery finder only to generate a candidate; it cannot override a VIN-specific OEM instruction.
Make a verification worksheet
Write down what you can see on the vehicle before contacting a parts desk. This browser-only form does not send or save your entries. Do not enter a full VIN here.
Use your verified values
Once you have the full tire notation, use the tire placard check. Once you have the battery label and OEM technology requirement, use the battery label check. Both tools screen obvious mismatches and leave final fitment unapproved.
When a portal lacks an older manual, ask a dealer or qualified parts desk for the matching publication using the VIN and model year. Do not substitute a nearby year, trim or powertrain.
