2015 Ford Focus ST Wheel Interchange

2015 Ford Focus ST Wheel Fitment Guide

Known OEM Fitment For 2015 Ford Focus ST

The confirmed fitment information currently available for the 2015 Ford Focus ST is listed below. Some wheel and tire dimensions are unknown or may vary by trim, package, market, or installed equipment. Do not treat missing values as recommendations.

A 5x108 bolt pattern alone does not confirm that a wheel fits. The wheel must also clear the brake components and suspension, use a suitable center bore, have an appropriate offset and width, and support the vehicle's load requirements. Confirm all unknown dimensions through the owner's manual, the vehicle's original wheel markings, a Ford dealer, or another reliable OEM source.

How To Use The Wheel Interchange Calculator

Use the calculator to compare wheels from a donor vehicle with wheels installed on your 2015 Ford Focus ST. Enter the donor wheel and tire information in the “Wheels from” fields, then enter the Focus ST information in the “Installed on” fields.

• Compare the bolt pattern, center bore, rim diameter, rim width, and offset.
• Use the custom wheel size controls when the donor wheel or proposed replacement is not already listed.
• Enter custom tire section width and aspect ratio when those values are known.
• Review the calculator's inner clearance, outer position, and diameter comparisons as screening information, not as a substitute for a physical test fit.
• When you change rim diameter, check the updated tire diameter comparison as well. A different wheel diameter normally requires a tire with a carefully selected sidewall height.

Because several original dimensions for this model are not provided here, use the calculator only after confirming the missing specifications. Compare the result with the wheel markings and OEM documentation before ordering.

Fitment Checklist Before You Buy

Confirm every item below for the exact wheel, tire, and vehicle configuration:

• The wheel uses the 5x108 bolt pattern.
• The wheel's center bore is compatible with the 63.3 mm vehicle hub. A smaller bore will not fit over the hub. A larger bore may require correctly sized hub-centric rings if the wheel manufacturer permits their use.
• The wheel uses compatible M12 x 1.5 wheel hardware, and the seat type matches the wheel. Thread size alone does not confirm nut compatibility.
• Wheel diameter, width, and offset are verified rather than assumed from a listing title.
• Brake caliper, suspension, fender, and inner-wheel clearance are checked. Spoke shape can affect brake clearance even when the diameter and offset appear suitable.
• The tire size is approved for the wheel width and provides adequate load capacity and speed rating.
• The rolling diameter is compared with the vehicle's verified original tire size to help avoid speedometer, clearance, and electronic-system concerns.
• TPMS sensor compatibility and valve-stem requirements are confirmed if the vehicle uses tire pressure monitoring.
• The replacement wheel's load rating is adequate for the vehicle and intended use.
• Used wheels are inspected for bends, cracks, corrosion around the bead seat, damaged mounting holes, and repaired structural damage.

Plus Sizing And Common Upgrades

Plus sizing means using a larger wheel diameter with a lower-profile tire while attempting to maintain a similar overall tire diameter. It does not automatically improve handling or fitment. The correct result depends on the Focus ST's verified original wheel and tire dimensions, the proposed wheel width and offset, brake clearance, tire load rating, and available fender and suspension clearance.

Use the calculator's custom wheel size and custom tire size fields to compare a proposed setup. Check the change in tire diameter, sidewall height, inner clearance, and outer position. Do not select a tire size solely because its rim diameter matches the wheel.

A wider wheel or tire can increase contact with suspension parts, fenders, or liners. A different offset can move the wheel inward or outward and may change scrub geometry. If the calculator indicates a close fit, perform a careful physical test fit before driving and check clearance with the steering turned through its full range and with the suspension loaded. Avoid spacers or adapters unless they are specifically engineered for the application and installed according to their manufacturer's requirements.

Installation Tips

Before installation, clean the hub mounting face and the wheel's mating surface. Remove rust and debris without removing metal from the mounting surfaces. Never place a finger between the wheel and hub while positioning a heavy wheel.

• Confirm that the wheel seats fully against the hub and that no debris prevents flat contact.
• Hand-start every fastener to avoid cross-threading.
• Use only wheel nuts or bolts with the correct thread, seat style, length, and diameter for the wheel.
• Snug the hardware in a crisscross sequence, lower the vehicle enough to prevent rotation, and tighten it with a calibrated torque wrench to the vehicle or wheel manufacturer's specified torque.
• Do not use an impact wrench for final torque.
• Check that the tire does not contact the strut, brake parts, steering components, fender, or liner.
• After installation, verify tire pressure using the vehicle manufacturer's recommendation.
• Recheck fastener torque after the mileage interval specified by the wheel or vehicle manufacturer, and inspect again after the first drive.

If a wheel does not seat correctly, stop the installation. Do not solve a clearance or seating problem by forcing the wheel, stacking spacers, or using mismatched hardware.

Tools And Helpful Supplies

Useful equipment includes a floor jack rated for the vehicle, properly positioned jack stands, wheel chocks, a calibrated torque wrench, a socket that fits the wheel hardware, a tire pressure gauge, and a wire brush or suitable hub-cleaning tool. A wheel fitment gauge or careful test-fit procedure can help identify clearance problems before the tires are mounted.

For compatible tool options, see automotive torque wrenches on Amazon and automotive wheel chocks on Amazon. Product compatibility, torque range, and condition should be checked before purchase.

FAQs

What is the bolt pattern for a 2015 Ford Focus ST?

The known bolt pattern is 5x108. This means five wheel fastener positions on a 108 mm pitch circle diameter. It is only one part of the complete fitment check.

What is the center bore for the 2015 Ford Focus ST?

The known center bore is 63.3 mm. A replacement wheel with a smaller bore will not fit over the hub. A larger bore may need properly sized hub-centric rings when allowed by the wheel manufacturer.

What wheel offset and width should I use?

The wheel offset and width are not provided in the known specifications for this page. Confirm them from the original wheel, its stamped markings, OEM documentation, or a Ford dealer. Then use the calculator to compare the proposed dimensions and physically verify clearance.

Can any 5x108 wheel fit this Focus ST?

No. A 5x108 wheel can still be unsuitable because of center bore, offset, width, brake clearance, wheel hardware, load rating, or spoke design. Check the complete specification rather than relying on the bolt pattern alone.

Can I install larger wheels on a 2015 Ford Focus ST?

A larger wheel may be possible, but the correct size is not established by the information provided here. Use verified original dimensions in the calculator, select a tire approved for the wheel, compare overall diameter, and confirm brake, suspension, and fender clearance before driving.

Why does changing rim diameter change the tire comparison?

A tire's rim diameter must match the wheel diameter. When the calculator changes rim diameter, it updates the tire diameter comparison so you can evaluate whether the proposed tire maintains a suitable overall diameter. The resulting tire size still needs to be checked against tire manufacturer requirements and OEM guidance.

Do I need hub-centric rings?

It depends on the replacement wheel's center bore and the wheel manufacturer's instructions. A wheel bore larger than 63.3 mm may require a correctly sized ring to center the wheel on the hub. Rings do not correct an incorrect bolt pattern, offset, wheel width, brake clearance problem, or unsuitable wheel hardware.

What torque should I use for the wheel fasteners?

The required torque value is not provided here and should not be guessed. Use the value specified by Ford or the wheel and fastener manufacturer for the exact vehicle and hardware. A calibrated torque wrench should be used for final tightening.
