Known OEM Fitment For 2017 Cadillac ATS

The specifications below are confirmed for at least one factory configuration of the 2017 Cadillac ATS. Other trims or option packages may differ. If your values do not match, verify using your door-jamb tire placard, owner’s manual, and the on-page calculator.

Bolt pattern 5x115
Center bore 70.3 mm
Lug/thread M12 x 1.5
OEM wheel diameter 18 in
OEM wheel width 8.0 in
OEM offset (ET) 42 mm
OEM backspacing 5.65 in
OEM tire size 225/45R17

Notes: The presence of both 18-inch wheel specs and a 17-inch tire size indicates multiple factory setups were available across trims or packages. Confirm your exact factory size from the tire placard and compare in the calculator before purchasing wheels or tires.

How To Use The Wheel Interchange Calculator

  • Start with Installed on (your vehicle) set to 2017 Cadillac ATS. Enter the OEM specs from your door-jamb placard if they differ from the table above.
  • Enter the donor vehicle wheel data under Wheels from. This can be another vehicle or an aftermarket wheel you are considering.
  • Use Custom wheel size to test rim diameter, width, and offset. The calculator shows how inner clearance, poke, and backspacing change.
  • Use Custom tire size to test section width and aspect ratio. When you change rim diameter, the tool updates overall tire diameter in the comparison.
  • Aim to keep overall tire diameter within about 2 to 3 percent of stock to maintain speedometer accuracy and ABS behavior.
  • Review brake clearance, fender poke, and strut clearance in the results. If anything is borderline, measure on the car before buying.

Fitment Checklist Before You Buy

  • Bolt pattern: Must be 5x115. Do not attempt to force-fit 5x114.3 without proper engineering solutions.
  • Center bore: Hub is 70.3 mm. Use hub-centric wheels or hub-centric rings if the wheel bore is larger than 70.3 mm.
  • Offset and backspacing: Compare new offset to the OEM reference above. Large changes can affect fender clearance, steering feel, and bearing load.
  • Brake caliper and barrel clearance: Physically test or verify with manufacturer drawings. Barrel profile varies by wheel model.
  • Load rating: Wheel and tire load index must meet or exceed OEM requirements for the ATS trim.
  • Tire diameter: Keep overall diameter close to stock. Use the calculator to check percentage difference.
  • Tire width and section shape: Wider tires may rub liners or fenders under compression or full lock. Check inner clearance to strut and spring perch.
  • TPMS: Plan to transfer sensors or use compatible replacements. Relearn or programming may be required.
  • Lug hardware: Thread is M12 x 1.5. Match seat type to wheel design (typically conical for aftermarket). Ensure proper thread engagement.
  • Spacers or adapters: Only if necessary. Use hub-centric spacers and extended studs or longer bolts as required. Recalculate offset in the tool.
  • Ride quality and gearing: Larger diameters and heavier assemblies affect acceleration, braking, and comfort.

Plus Sizing And Common Upgrades

Plus sizing changes rim diameter while keeping overall tire diameter close to stock. This helps maintain speedometer accuracy and handling balance. Because factory sizes for the 2017 ATS vary by trim, use your own OEM size as the baseline in the calculator.

  • Plus 0: Same rim diameter, wider wheel and tire. Check inner clearance and fender poke.
  • Plus 1: Increase rim diameter by 1 inch and reduce tire sidewall to keep overall diameter similar. Example approach: simulate moving from a 17-inch tire to an 18-inch tire with a lower aspect ratio.
  • Plus 2: Similar idea to Plus 1 but with a 2-inch larger rim. Carefully verify clearance, especially over bumps and at full steering lock.

Use the calculator to compare inner clearance change, outer poke change, and percent difference in overall diameter. If the result shows more than about 2 to 3 percent difference, consider a different tire size.

Installation Tips

  • Test fit each front and rear position before mounting tires. Spin the wheel to check caliper and knuckle clearance.
  • Clean hub faces and wheel mounting pads. Remove rust and debris to prevent runout and vibration.
  • If using hub-centric rings, seat them fully on the wheel. Rings do not replace proper torque or correct bolt pattern.
  • Start lugs by hand. Tighten in a star pattern in stages. Use a calibrated torque wrench to final torque per the owner’s manual.
  • Re-torque after 50 to 100 miles. Check for any rubbing at full lock and over bumps.
  • For TPMS, move your sensors or install compatible new ones, then complete any required relearn procedure.

Tools And Helpful Supplies

FAQs

  • What is the bolt pattern on the 2017 Cadillac ATS?

    5x115.

  • What center bore does the ATS use?

    70.3 mm. If an aftermarket wheel has a larger bore, use appropriate hub-centric rings.

  • What lug/thread size do I need?

    M12 x 1.5. Match the lug seat style to the wheel design.

  • What is the factory wheel offset?

    One confirmed OEM setup uses ET 42 mm on an 18x8.0 wheel. Other trims may differ. Verify with OEM documentation or your original wheel markings.

  • My OEM tire size is different from 225/45R17. Is that normal?

    Yes. The ATS was offered with multiple factory wheel and tire packages. Use your door-jamb placard and the calculator to set your exact baseline.

  • Can I use 5x114.3 wheels on a 5x115 hub?

    This is not recommended. Mismatched patterns can cause unsafe clamping and vibration. Use the correct 5x115 wheels.

  • Do I need hub-centric rings?

    Only if the wheel bore is larger than 70.3 mm. OEM wheels with 70.3 mm bores are hub-centric without rings.

  • What is the correct lug nut torque?

    Torque specifications can vary. Consult the owner’s manual or an official service manual for your exact trim, then use a torque wrench and re-check after 50 to 100 miles.

  • How much can I change tire diameter?

    Aim to stay within about 2 to 3 percent of your OEM overall diameter. Use the calculator to verify.

  • Will wider tires fit without rubbing?

    It depends on wheel width, offset, and tire profile. Use the calculator to compare inner clearance and outer poke, then measure on the car if near the limits.

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
