2007 Cadillac XLR Wheel Interchange

2007 Cadillac XLR Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2007 Cadillac XLR

The table shows factory wheel and tire specifications reported for the 2007 Cadillac XLR. If your car has special packages or the XLR-V performance variant, some dimensions may differ. Always confirm with your owner’s manual, the driver-door placard, and by using the on-page calculator.

Notes:

• 5x120.70 is also commonly written as 5x120.7 or 5x4.75 in.
• Do not assume all trims share the same widths, offsets, or tire sizes. Verify your exact vehicle.

How To Use The Wheel Interchange Calculator

The calculator on this page lets you compare Wheels from a donor vehicle against Installed on your vehicle. It also supports a Custom wheel size and Custom tire size so you can preview changes before you buy.

• Set Installed on to 2007 Cadillac XLR. If any fields are blank, enter the OEM values above.
• Choose a donor vehicle or directly enter a Custom wheel size by rim diameter, rim width, and offset.
• Enter a Custom tire size by section width and aspect ratio. When you change rim diameter, the tool updates tire diameter in the comparison so you can keep overall diameter consistent.
• Check the inner clearance change to the strut and brakes and the outer poke change toward the fender. Aim to avoid contact on both sides through full steering and suspension travel.
• Use the bolt pattern and center bore filters to find only 5x120.70 wheels and wheels that are hub-centric to 70.1 mm or larger with rings.
• If results vary by trim, confirm against your door placard and service information before purchasing.

Fitment Checklist Before You Buy

• Bolt pattern must be exact: 5x120.70 mm. 5x120 is not the same and is not recommended.
• Center bore: 70.1 mm. The wheel’s center bore must be 70.1 mm or larger. If larger, use hub-centric rings to 70.1 mm. If smaller, it will not fit.
• Offset and backspacing: Start from OEM ET 61 mm and 6.4 in backspacing. Use the calculator to keep inner and outer clearances safe for your brakes, suspension, and fenders.
• Brake and suspension clearance: Confirm spoke and barrel clearance over calipers and knuckles. When in doubt, test-fit before mounting tires.
• Tire diameter: Keep overall rolling diameter close to stock to protect ABS, traction control, and speedometer accuracy. The calculator shows the difference.
• Load rating: Wheel and tire load ratings must meet or exceed OEM.
• TPMS: Verify sensor type and compatibility. Plan to transfer or program sensors as required by OEM procedures.
• Lug hardware: Threads are M12x1.5. Match the seat type of your wheels and correct shank or conical profile. Do not mix seat types.
• Spacer use: Only if necessary. Use quality hub-centric spacers with adequate hub lip engagement and longer studs when required.
• Return policy: Confirm you can return wheels if a test-fit reveals clearance issues.

Plus Sizing And Common Upgrades

If you plan to change sizes, use the calculator to visualize inner and outer movement and tire diameter. General guidance:

• Overall tire diameter: Keep within a small percentage of OEM to maintain correct ride height and speedometer behavior.
• Wider wheels and tires: Increasing width can improve grip but reduces clearance. Check inner clearance to struts and knuckles and outer clearance to fenders and liners.
• Larger diameters: Going up in rim diameter usually requires a lower-profile tire to keep overall diameter close to OEM. Check ride quality and pothole risk.
• Staggered setups: If considering different widths front and rear, verify clearances at both ends and ensure tire load index and rolling diameters remain appropriate.
• Hub-centric fit: Aftermarket wheels usually have larger bores. Use 70.1 mm rings for a vibration-free fit if the wheel bore is larger than 70.1 mm.

Installation Tips

• Park on level ground, set the parking brake, and chock wheels.
• Break lug torque slightly before lifting. Lift at factory jack points per the service manual and support with jack stands.
• Clean the hub face and center pilot with a wire brush. Remove rust and debris for perfect seating. Do not apply lubricants to studs or lug seats.
• If using hub-centric rings, press them fully into the wheel bore before mounting.
• Mount the wheel and hand-thread all lug nuts to avoid cross-threading. Snug in a star pattern.
• Lower the vehicle and torque lugs in a star pattern to the factory torque specification from your owner’s manual or service information. Do not guess the value.
• Re-torque after the first short drive and again after 50 to 100 miles.
• TPMS: Install compatible sensors and perform the OEM relearn or programming procedure as required.

Tools And Helpful Supplies

• 1/2 in drive torque wrench: Search on Amazon
• Impact-rated socket set for lug nuts: Search on Amazon
• M12x1.5 lug nuts that match your wheel seat type: Search on Amazon
• Hub-centric rings to 70.1 mm if your wheel bore is larger: Search on Amazon

Also useful: floor jack and jack stands, breaker bar, wire brush, tire pressure gauge, and a paint marker to mark torqued lugs.

FAQs

• What is the OEM bolt pattern for the 2007 Cadillac XLR?

  5x120.70 mm.

• Will 5x120 wheels fit a 5x120.70 car?

  No. 5x120 and 5x120.70 are different. Use the exact 5x120.70 pattern or professionally engineered adapters designed for this conversion. Mismatched patterns are unsafe.

• What is the center bore I need?

  70.1 mm. A wheel with a larger bore can be used with 70.1 mm hub-centric rings. A smaller bore will not fit the hub.

• What is the stock wheel size and offset?

  19x8.0 in with ET 61 mm and about 6.4 in backspacing are reported OEM specs. If your trim differs, confirm via your door placard and service information.

• What lug nuts does it use and what torque should I apply?

  Threads are M12x1.5. The correct torque value can vary by wheel and is specified by Cadillac. Check the owner’s manual or service information and torque in a star pattern.

• Do I need hub-centric rings with aftermarket wheels?

  Only if the new wheel’s center bore is larger than 70.1 mm. Choose rings that reduce the wheel bore to 70.1 mm and match the wheel’s bore precisely.

• How do I pick an offset for aftermarket wheels?

  Use ET 61 mm as your baseline and the calculator to see inner clearance and outer poke changes. Verify brake, suspension, and fender clearances at full lock and full compression before buying.

• Can I run a staggered setup?

  Possibly, but it depends on widths, offsets, and tires. Use the calculator to validate both axles, ensure correct load index, and keep rolling diameters appropriate. Check OEM guidance if your vehicle has stability control considerations.

• Will I need new TPMS sensors?

  You can usually transfer existing sensors or buy compatible replacements. Confirm sensor type and follow the OEM relearn or programming procedure after installation.
