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.
Low-voltage battery groups
No source-backed rows are available for this exact selection.
How to verify this model year’s 12V battery
Our 2025 Honda Civic page has tire observations, but no low-voltage battery application for this year. Open Honda owner resources. Select the vehicle year and model to open the owner's manual; compare the actual door placard. Find the battery replacement and jump-start sections, then photograph the installed battery label and its location before shopping.
- Use the VIN, powertrain and equipment list when asking the manufacturer’s parts desk for the current replacement part and any supersession.
- Confirm battery position, voltage, group or OEM case designation, AGM/EFB/flooded technology, terminal orientation, hold-down and venting.
- Ask whether a battery-management reset or registration is required. Use Interstate’s vehicle finder only as a candidate cross-check, then compare an exact part in the battery-label tool.
A tire size does not establish a battery group. On a hybrid or EV, identify the low-voltage battery separately from the high-voltage traction pack.
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.
