2005 Buick LeSabre Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2005 Buick LeSabre.

Tl;dr

You have a 2005 Buick LeSabre with these OEM wheel specs: 5x115 bolt pattern, 70.3mm center bore, M12 x 1.5 thread, 16x6.5 rim, ET43 offset, 4.94 inch backspacing, and factory tire 215/70 (R15 listed). There is a mismatch between rim diameter (16) and tire rim diameter (R15) in the data. Confirm rim and tire diameters before buying wheels or tires. Use the on-page calculator and OEM sources to verify fitment.

Recommendation

First, verify the correct wheel rim diameter and tire rim diameter. Check the vehicle placard, owner's manual, or dealer parts department. Then use the site calculator to compare donor wheels to your LeSabre. If changing wheels, pick wheels that match 5x115 bolt pattern and 70.3mm center bore or plan hub-centric rings. Use M12 x 1.5 lug hardware sized for the wheel seat type. Choose tires that match the confirmed rim diameter and maintain overall diameter within safe tolerance.

Impact

Getting bore, bolt pattern, or thread wrong prevents safe installation. Correct bolt pattern ensures the wheel mounts to studs. Matching center bore prevents hub-centric runout. Correct lug nuts prevent stripped threads and loose wheels. A wrong tire-to-rim diameter pairing risks bead seating failure and speedometer error. Using the calculator shows changes in track width, speedometer, and clearance instantly.

Risks

  • Misreading the rim vs tire diameter causes fitment failures. This is already flagged in your data.
  • Using non hub-centric wheels can cause vibration if the bore does not center on the hub.
  • Incorrect lug nut thread or seat type can strip studs or allow the wheel to loosen.
  • Excessive offset change may cause rubbing on suspension or fender lips.
  • TPMS incompatibility or missing sensors can trigger warning lights or loss of monitoring.

Next actions

Checklist for a quick, safe workflow.

  • Confirm OEM rim diameter and tire rim diameter. Use the door placard or owner manual.
  • Open the on-page calculator. Enter your confirmed stock wheel and tire sizes. Compare donor wheels now.
  • If center bore differs, plan hub-centric rings sized to 70.3mm center bore for safety and balance.
  • Buy lug nuts that match M12 x 1.5 thread and the wheel seat type. Verify seat style before purchase.
  • Verify TPMS compatibility or plan sensor swap if needed.
  • Have a shop or dealer confirm OEM torque spec and final inspection before driving.
  • Keep these gotchas in mind: do not assume tire 215/70R15 fits a 16 inch rim. Confirm all diameters first.

Next steps: confirm dimensions, run the on-page calculator, then source hardware.
