What size tires go on a Ford Flex?
There isn’t one universal tire size for all Ford Flex models; it depends on the model year and wheel package. Most factory setups use 18-inch wheels with 235/65R18 or 235/60R18 tires, while some trims with 20-inch wheels use 245/50R20 tires.
Understanding tire sizes on the Ford Flex
The Ford Flex, produced from 2009 to 2019, offered several wheel and tire configurations. The exact size you need depends on your year, trim, and whether your vehicle came with standard 18-inch wheels or larger optional wheels. Always verify the recommended size for your specific vehicle to ensure proper fitment and performance.
Common factory tire sizes by wheel package
The following sizes reflect the most commonly equipped configurations found on stock Ford Flex models. Exact size can vary by year and trim, so always confirm with the door placard or owner’s manual.
- 18-inch wheels: typically 235/65R18 or 235/60R18
- 20-inch wheels: typically 245/50R20
Keep in mind that some late-model or special-edition Flexes could differ, and some markets may have had alternative sizes. Always verify the exact size for your vehicle before purchasing tires.
How to verify your exact tire size
To confirm your specific size for your Ford Flex, use these steps:
- Check the driver’s door jamb placard for the recommended tire size and cold inflation pressure.
- Inspect the sidewall of your current tires for the size inscription (for example, P235/60R18 or 245/50R20).
- Consult the vehicle’s VIN in Ford’s Owner site or the official manual to confirm the original equipment size.
- When replacing tires or changing wheel sizes, stick to sizes that meet or exceed the OEM load index and speed rating.
Note: If you’re upgrading to different wheels or pursuing winter tires, verify that the overall diameter is close enough to the OEM specification to prevent speedometer and ABS/traction control issues.
Summary
In short, tire size for a Ford Flex varies by year and wheel package. The most common factory configurations are 18-inch wheels with 235/65R18 or 235/60R18, and 20-inch wheels with 245/50R20. Always check the door placard or VIN-based documentation to confirm the exact size for your vehicle, and match the load and speed ratings when replacing tires.
