What size tires will fit on a Ford Ranger?
There isn't a single universal tire size for every Ford Ranger. The correct size depends on the model year, trim level, and wheel choice. Always start with the size listed on the door placard or in the owner's manual. In general, Rangers have used wheels ranging from 14 to 18 inches across generations, with overall tire diameters roughly spanning from the mid-20s to low-30s inches depending on configuration.
Stock tire sizes you might encounter
To understand what fits your truck without modifications, compare your current tires to the factory specification printed on the placard stuck to the driver’s door jamb or inside the glove box/spec sheet. Here are representative examples by era to illustrate how sizes evolved, though exact numbers vary by trim and region:
Illustrative examples by era
- Older Rangers (1980s–early 1990s) commonly used smaller wheels, such as 14- or 15-inch rims with tires around P205/75R14 to P235/75R15.
- Rangers from the late 1990s through the 2000s often came with 15- to 16-inch wheels and tires like P235/70R15, P235/75R15, or P255/70R16, depending on trim and cab configuration.
- Modern Rangers (2019–present) frequently use 16- to 18-inch wheels as stock, with tire sizes around P265/65R17 or similar patterns on many trims; some configurations use P235/60R17 or P235/55R18 depending on market and package.
Always verify the exact size for your vehicle; the placard will show the precise recommended size for the original wheel and tire package.
Upgrading or changing tire sizes safely
If you’re considering a change from stock, you’ll need to balance fitment concerns with speedometer accuracy, gearing, and clearance. The following guidelines help ensure any upgrade is safe and practical.
- Keep overall tire diameter within a safe range of the factory spec. A common rule is to stay within about plus or minus 3% of the original circumference to avoid speedometer error and ABS/traction control issues.
- Match wheel width and offset to avoid rubbing on the fenders, control arms, or brake components. A wheel with too much width or incorrect offset can cause clearance problems.
- Understand the impact on ride quality and load rating. Bigger or wider tires can alter ride feel and may require higher load-rated tires for heavy use.
- Consider potential modifications if you go significantly larger (lift kits, trimming, or fender work). More aggressive sizes often require suspension tweaks and alignment tuning.
- Recalibrate the speedometer if needed. Significant changes in tire diameter can affect readouts and cruise control accuracy.
By following these guidelines, you can select a tire size that fits your Ranger’s capabilities while preserving safety and performance.
Practical steps to verify fitment
Before purchasing, take these steps to confirm fitment for your exact truck configuration:
- Check the door placard for the recommended tire size and wheel diameter.
- Measure clearance with each suspension articulation; test full steering lock and full suspension travel to ensure no rubbing.
- Consult your dealer or a reputable tire shop about compatibility with ABS, traction control, and speedometer calibration.
Taking these steps helps avoid fitment problems and ensures the tires you choose meet safety and performance expectations.
Summary
The Ford Ranger’s tire size is not universal; it depends on year, trim, and wheel choice. Start with the factory spec on the door placard, then consider safe upgrades by maintaining similar overall diameter, matching wheel width/offset, and accounting for clearance and drivetrain systems. For precise numbers, consult the owner’s manual or a Ford dealer, and use a trusted tire calculator or shop to confirm fitment.
