What size tires are on a 2012 Ford Explorer?
The most common original equipment tire size for the 2012 Ford Explorer is P245/60R18 on 18-inch wheels; some trims with upgraded wheels used larger sizes such as P255/45R20 on 20-inch wheels. Exact sizing varies by trim, option package, and whether the vehicle is front-wheel drive or all-wheel drive. Always verify the size stamped on the vehicle’s door placard or in the owner's manual.
Common OE Tire Sizes by Wheel Option
Below are the tire sizes most often associated with common wheel configurations for the 2012 Explorer. Variations can occur based on trim level and factory options, so always confirm with your specific vehicle.
- 18-inch wheels: P245/60R18
- 20-inch wheels: P255/45R20
- Note: Some configurations or earlier production runs may have used different sizes if a non-standard wheel package was selected. Always check the door placard or stamping on the tire for your exact size.
In all cases, the exact tire size can differ by trim and wheel package, so use the vehicle-specific markings to confirm your OE size.
How to Verify Your Tire Size
Use these steps to confirm the exact tire size currently on your 2012 Explorer. This ensures you purchase the correct replacement tires or compatible alternatives.
- Inspect the tire sidewall for a size code such as P245/60R18. The numbers indicate width, aspect ratio, construction, and wheel diameter.
- Check the driver’s door jamb placard. It lists the factory-recommended tire size for the vehicle as it left the factory.
- Consult the owner’s manual or original window sticker (Monroney label) for the exact size specified for your trim and wheel package.
- If the wheels have been swapped, measure the current wheel diameter and look for the closest matching OE size to maintain proper overall diameter.
Once you’ve identified the correct size, you can reference it when shopping for replacements or when deciding whether a wheel upgrade is feasible without affecting handling or speedometer accuracy.
Tire Replacement Considerations
Diameter and compatibility
When replacing tires, aim to match the original overall diameter as closely as possible to preserve speedometer accuracy, ABS operation, and drivetrain performance. Large deviations can affect braking and traction systems.
- Keep the overall diameter within about 2-3% of the OEM specification to avoid speedometer and odometer errors.
- Try to match the tire width and aspect ratio to maintain similar load handling and performance characteristics.
- If changing wheel size (for example, moving from 18" to 20" wheels), ensure the new tires keep a comparable overall diameter and verify clearance in the wheel wells and suspension components.
- Choose tires that match the vehicle’s intended use (all-season, highway, or dedicated all-terrain) and consider load and speed ratings suitable for your Explorer’s weight and performance.
After replacing tires or changing wheel sizes, it’s wise to have the vehicle rebalanced and, if needed, aligned to ensure optimal handling and even wear.
Summary
The 2012 Ford Explorer generally rode on 18-inch wheels with P245/60R18 tires, while some trims offered 20-inch wheels with P255/45R20 tires. Exact sizes depend on trim and factory options, so always verify the size via the door placard, owner’s manual, or original window sticker. When replacing tires, prioritize matching the overall diameter and appropriate load/speed ratings to maintain performance and safety.
