2015 Ford Explorer Tire Sizes & Pressure
Find the correct tire size and cold inflation pressure for your Explorer and understand TPMS, tire wear and replacements.
Confirm the vehicle's engine, trim, drivetrain, market and equipment. The exact procedure may differ, even within the same model year.
2015 Ford Explorer reference
| Where to verify | What to read |
|---|---|
| Driver-door tire placard | Original tire size and cold pressure for this vehicle |
| Current tire sidewall | Installed size, load rating, speed rating and wear |
| Ford owner’s manual | Rotation, TPMS and temporary spare precautions |
Do not publish a single PSI or tire fitment as universal for all trims and wheel packages.
Use the driver-door label first
The Tire and Loading Information label on the driver-side door opening identifies the original tire size and Ford-specified cold inflation pressure for the particular vehicle. Check this label rather than relying on a tire chart for every 2015 Explorer. Trim, wheel option, spare tire and previous owner modifications can all alter the tire currently fitted.
Tire sizes vary
The 2015 Explorer was sold with different wheel and tire packages depending on trim and options. Some vehicles have 18-inch wheels, while other packages may have 20-inch wheels. A tire size is more than its rim diameter: the complete marking contains section width, aspect ratio, construction and wheel diameter. Confirm load and speed ratings as well.
How to check pressure
Check pressures when tires are cold, before a long drive or after the tires have cooled appropriately. Use a reliable gauge and adjust to the vehicle placard, not the maximum number molded onto the tire sidewall. Pressure rises during driving due to heat. Do not bleed a warm tire down to the cold placard value.
When TPMS illuminates
A steady low-tire-pressure warning generally calls for a safe pressure inspection of all road tires. If the warning flashes before remaining illuminated, there may be a system fault requiring diagnosis. Temperature drops can cause an otherwise healthy tire to fall below the pressure threshold; repeated loss from one wheel suggests a leak.
Tire rotation and uneven wear
Ford recommends tire inspection and rotation during regular maintenance. Compare shoulder wear, centre wear and differences across an axle; these patterns can indicate incorrect pressure, alignment, suspension wear or driving conditions. Measure tread depth rather than judging tread health solely by appearance.
Replacing one tire on AWD
An AWD Explorer may be sensitive to differences in rolling circumference across tires. Confirm Ford-compatible size and tread-matching advice before mixing new and worn tires. Do not assume that a tire with the same nominal size always has identical outside diameter between brands.
Spare tire and towing
The temporary spare may have different limitations from the regular wheels. Read the sidewall and Ford spare-tire instructions before driving on it, and do not tow or drive normally if restricted by the spare instructions. Also respect the vehicle load label when carrying passengers or a trailer.
The door placard settles the pressure question
Tire sidewalls list a maximum permissible pressure, not necessarily the correct pressure for the Explorer. For normal cold inflation use the driver-door placard or Ford’s exact vehicle specification. Review it again when wheel sizes have been changed, and measure before driving enough to warm the tires.
Tire matching matters more on AWD vehicles
Significant differences in circumference or uneven wear among tires can place unwanted demand on the AWD driveline. Use matched size, load rating, seasonal type and appropriate tread condition. If replacing fewer than four tires, have a qualified tire shop check Ford’s matching requirements and the remaining tread depths.
Check the door placard before inflating
The pressure printed on the tire sidewall is generally its maximum permitted pressure, not the vehicle maker’s recommended cold inflation setting. Use the driver-side door placard for the installed tire size and cold pressure, then check with a reliable gauge before driving. When buying a full replacement set, match the specified load and speed ratings as well as dimensions. On AWD models, substantially mismatched rolling circumference or uneven wear can create drivetrain concerns. Record tread depth at several points to detect alignment or suspension problems early.
Use the driver-door label as the pressure authority
The tire and loading label on the driver-side door jamb gives the cold inflation pressure for the vehicle as originally equipped. The pressure printed on a tire sidewall is a maximum load-related rating, not the recommended everyday inflation pressure. If wheels or tire sizes have changed, verify the replacement load rating and fitment before using a generic online pressure chart.
Use the correct model-year manual and current service information. Stop if instructions or safety precautions are unclear, and use a qualified technician for work you cannot verify.
