2013 Cadillac SRX Wheel Interchange

Known OEM Fitment For 2013 Cadillac SRX

The values below are taken from data provided for this page. Some trims may use different wheel and tire packages. If any value is missing for your exact trim, confirm it on your driver door placard, your owner manual, OEM part numbers, and by using the on-page calculator.

Note: The table shows a 20x8.5 ET50 wheel and a 235/65R18 tire from the provided data. This indicates multiple OEM packages may exist for the 2013 SRX. Always verify your specific trim using the door placard and the calculator before purchasing wheels or tires.

How To Use The Wheel Interchange Calculator

The calculator on wheelinterchange.com lets you compare a donor setup against your 2013 Cadillac SRX and try custom sizes safely.

• Set Installed on to 2013 Cadillac SRX.
• Optional: Set Wheels from to a potential donor vehicle you are considering.
• Use Custom wheel size to try a new rim diameter, width, and offset. The tool will compare this to your SRX baseline.
• Use Custom tire size to enter section width and aspect ratio. When you change rim diameter, the calculator updates the compared tire diameter so you can keep overall diameter near stock.
• Review the calculator outputs to see how inner clearance and outer position change, and how overall tire diameter compares to your baseline.
• Iterate until changes are within safe margins for clearance and overall diameter. Then confirm against your vehicle’s door placard and a physical test fit.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 6x120.
• Center bore: 66.9 mm hub is required. Aftermarket wheels with larger bores need hub centric rings sized to 66.9 mm at the vehicle side.
• Lug hardware: Thread size is M14 x 1.5. Confirm lug seat type for your wheels and follow Cadillac recommendations for dry or lubricated threads. Do not mix seat types.
• Offset and backspacing: The provided OEM reference is 20x8.5 ET50 with 6.22 in backspacing. Deviating offset or width changes inner clearance and outer poke. Use the calculator to visualize changes and ensure brake, strut, and fender clearance.
• Tire overall diameter: Keep new tire diameter close to your OEM baseline to protect ABS, gearing, and speedometer accuracy. A common guideline is within about 3 percent, but confirm with the calculator and door placard.
• Brake caliper clearance: Spoke and barrel shapes vary. Always test fit one wheel on the front axle to ensure caliper clearance.
• Load and speed ratings: Wheels and tires must meet or exceed SRX OEM load and speed ratings for safety.
• TPMS compatibility: Plan for sensor transfer or compatible new sensors and a relearn procedure.
• Torque specs: Use the torque value from your owner manual or service information. Re-torque after short mileage.

Plus Sizing And Common Upgrades

The data on this page shows at least two OEM directions for the 2013 SRX: a 20x8.5 ET50 wheel and a 235/65R18 tire. That suggests the platform supports both 18 inch and 20 inch packages depending on trim. If you are upsizing or downsizing:

• Match overall tire diameter: Start with your door placard size. Use the calculator’s Custom wheel size and Custom tire size to find a tire that keeps total diameter near your baseline when changing wheel diameter.
• Keep sensible offset: Use the ET 50 mm reference from the provided 20x8.5 spec as a starting point. Adjust carefully in the calculator to maintain inner clearance to the strut and outer clearance to the fender.
• Winter or utility sets: Many owners prefer a narrower wheel and tire for winter. Use your placard size as the baseline, then simulate alternatives in the calculator and confirm brake clearance before purchasing.
• Staggered setups: If considering a staggered width, confirm rotation limitations, tire availability, and that both axles maintain proper clearance.

Installation Tips

• Prepare the hub: Clean the 66.9 mm hub face and pilot with a wire brush so wheels sit flush. Remove rust scale and old anti-seize from the mating surface.
• Use correct hub centering: If the wheel bore is larger than 66.9 mm, install quality hub centric rings to prevent vibration.
• Hardware check: Verify lug nut type, thread engagement, and seat match. Minimum thread engagement should meet OEM guidance. Do not mix conical, ball, or mag seats.
• Tightening: Hand start all lugs, snug in a star pattern, then torque to the factory spec using a calibrated torque wrench. Re-torque after 50 to 100 miles.
• TPMS: Transfer sensors carefully or install compatible new sensors and perform the relearn procedure for Cadillac.
• Test fit: Mount one front wheel and turn lock to lock. Check strut, spring perch, brake line brackets, and fender liner under compression before mounting all four.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• GM TPMS relearn tool
• Hub centric rings 66.9 mm vehicle side
• Tire pressure gauge

FAQs

• What is the bolt pattern on a 2013 Cadillac SRX?

  The provided data lists 6x120. Always verify against your door placard or service information for your exact trim.

• What center bore do I need for aftermarket wheels?

  The hub pilot is 66.9 mm. If your wheel bore is larger, use hub centric rings that step the wheel down to 66.9 mm at the vehicle side.

• What is the OEM wheel offset?

  The data includes a 20x8.5 wheel with ET 50 mm and 6.22 in backspacing. Other trims may differ, so confirm by checking your OEM wheel part number or measuring your current wheels.

• What tire size is stock for 2013 SRX?

  The data on this page includes 235/65R18. Multiple OEM sizes may exist. Check your door placard for the exact factory size for your vehicle.

• Will wheels from another 6x120 vehicle fit my SRX?

  Possibly, but do not rely on bolt pattern alone. You must confirm center bore compatibility or use rings, offset and width for clearance, brake caliper clearance, load rating, and tire diameter. Use the calculator to compare the donor setup to your SRX and perform a physical test fit.

• Can I run 20 inch wheels on my SRX?

  The data shows a 20x8.5 ET50 wheel as an OEM reference. If changing wheel diameter, use the calculator to choose a tire that keeps overall diameter near your baseline and confirm all clearances.

• What lug nuts does the SRX use?

  Thread size is M14 x 1.5 per the data. Seat style can vary by wheel design, so match the seat type to your wheels and follow Cadillac torque guidance from the owner manual.

• Do I need spacers?

  Only if required to resolve clearance issues. If spacers are used, they must be high quality, hub centric, and paired with appropriate studs or bolts. Verify legality and consult a professional if unsure.
