What size tires fit on stock Ranger?
The correct stock tire size for a Ford Ranger depends on the model year, trim, and wheel size; there is no single universal size. Rangers have shipped with 14–17 inch wheels, and the corresponding factory tires have ranged from roughly 205/75R14 to 265/70R17.
To confirm the exact factory size for your specific Ranger, check the driver’s side door jamb tire placard, consult the owner’s manual, or pull the vehicle’s build sheet using the VIN. This article outlines how to verify the size and provides guidance on typical stock sizes by wheel diameter.
How to determine the correct stock size
Use the following steps to locate the exact factory tire size for your Ranger. This ensures you choose replacements that maintain proper clearance, steering feel, and speedometer accuracy.
- Look at the driver’s side door jamb placard for the “Tire Size” line, which shows the original equipment size.
- Consult the owner’s manual or the vehicle’s window sticker/build sheet if available.
- Inspect the tire sidewall of the currently mounted tires; the size is printed there (for example, P205/75R14).
- If documentation isn’t accessible, use the VIN to pull the original equipment (OE) tire size from Ford’s dealer systems or an official VIN decoder.
- Verify the wheel diameter and check for any clearance issues in the wheel wells or with ABS/speedometer calibrations.
By following these steps, you’ll confirm the OE size for your specific Ranger and ensure any replacements stay within factory tolerances.
Common stock tire sizes by wheel diameter
Here are representative stock-size ranges you’ll typically see on Rangers, organized by wheel diameter. The exact size depends on year, trim, and whether the truck is 2WD or 4WD, as well as optional equipment. Always verify the OE size for your specific vehicle.
- 14-inch wheels: P205/75R14 or P215/75R14
- 15-inch wheels: P205/75R15, P225/75R15, or P235/75R15
- 16-inch wheels: P255/70R16 or P265/70R16
- 17-inch wheels: P265/65R17 or P275/65R17
These sizes reflect common stock configurations across multiple Ranger generations. Exact sizing for your truck may differ, so always confirm with the OE sheet for your VIN.
Important fit considerations
When selecting tires within or near the stock range, keep these factors in mind to preserve performance and fitment.
- Overall diameter should stay within about 3% of the stock size to avoid speedometer error and drivetrain stress.
- Check for rubbing against fenders, suspension components, and brake calipers, especially on 4x4 models or when using larger tires.
- Use an appropriate load rating and speed rating suitable for the Ranger’s weight and typical use (hauling, towing, highway driving).
- Consider wheel offset and backspacing; a different offset can cause rubbing even with identical tire sizes.
- Upgrading beyond stock sizes can affect ABS, traction control, and stability systems; modifications may be required for optimal performance.
Summary
There isn’t a single “stock” tire size for every Ford Ranger. Start with the original equipment size listed on the door placard or build sheet, confirm it with the VIN when needed, and choose tires that maintain the factory diameter and clearance. With the correct OE size in hand, you can select replacements that preserve handling, gearing, and speedometer accuracy for your specific Ranger.
