Buick LeSabre Wheel Specs
2005 Buick LeSabre stores 3 wheel configurations. Rim diameter runs 15–17 in. Offset runs 38–43 mm. Bolt pattern is 5×115. Vehicle hub bore is 70.3 mm.
Figures are stored catalog values. A matching bolt pattern does not prove the wheel clears the brakes or the body.

Questions
What wheel sizes does the Buick LeSabre use?
Buick LeSabre in 2005 stores rim diameters of 15 in, 16 in, and 17 in, with widths of 6 in, 6.5 in, and 7 in. 3 configurations are listed below. These are catalog rows, not a single universal size.
What is the Buick LeSabre bolt pattern?
The stored bolt pattern in 2005 is 5×115.
What offset range is stored for the Buick LeSabre?
Stored offset in 2005 is 38–43 mm. Offset is the distance from the rim centerline to the mounting face. A positive value places the face toward the outside of the wheel.
What is the Buick LeSabre center bore?
The year hub record is 70.3 mm (auto_model_year.center_bore_id → rim_center_bore). Trim center bore is 70.3 mm (zdonor_wheel_size_trim.center_bore).
Does Buick LeSabre wheel size vary by year?
Wheel rows are stored for 7 years, from 1999 through 2005. This page shows the 2005 rows. Choose another year to see that year's diameters. Years are not collapsed into one size.
What does wheel offset mean?
Offset is how far the mounting face sits from the rim centerline, in millimeters. It is not the same number as backspacing. Backspacing on this page is calculated from rim width and offset because the rim table does not store backspacing.
What is the difference between positive and negative offset?
Positive offset moves the mounting face toward the street side, which tucks the wheel inward relative to a zero offset. Negative offset moves the face toward the brake side, which pushes the wheel outward. The stored values on this page are the catalog offsets, not a recommendation to change them.
Can I use wheels with a different bolt pattern?
A different bolt pattern does not mount on 5×115 studs. An adapter is a separate part that converts one pattern to another. This page can look up adapter products after you choose a target pattern. It does not decide that an adapter is safe for this vehicle.
When are hub-centric rings needed?
A hub-centric ring fills the gap when the wheel's center bore is larger than the vehicle hub. The stored vehicle hub in 2005 is 70.3 mm. A ring is not required when the bores match, and a ring cannot make a smaller wheel bore fit a larger hub.
How do I determine the required hub-ring size?
Use the vehicle hub bore of 70.3 mm and the center bore printed on the aftermarket wheel. The ring size is the wheel bore minus the hub bore. This page does not copy the hub bore into the wheel-bore field.
How does changing wheel width affect fitment?
Adding width grows the wheel on both sides of the centerline. The offset calculator estimates how far the inner and outer lips move. That estimate does not establish brake, suspension, or fender clearance.
How does offset affect wheel position?
Lowering the offset number moves the wheel outward. Raising it moves the wheel inward. The calculator on this page uses the standard width-and-offset geometry and labels the result as a position change, not a fitment verdict.
What should I verify before buying aftermarket wheels for a Buick LeSabre?
Confirm bolt pattern, center bore, thread, offset, and load rating on the wheel you are buying. Brake clearance, suspension clearance, and body clearance are not stored in this catalog, so a matching bolt pattern is not proof the wheel fits.
Can I install wider wheels on a Buick LeSabre?
Stored widths in 2005 are 6 in, 6.5 in, and 7 in. A wider wheel can be compared with the offset calculator. The catalog does not say whether a wider wheel clears the brakes or the fender.
What is the difference between wheel bore and vehicle hub bore?
Vehicle hub bore is the diameter of the hub that the wheel centers on, taken from the model-year rim_center_bore record. Wheel center bore is the hole in the wheel. On this page the trim center bore comes from zdonor_wheel_size_trim.center_bore. When those numbers differ, both stay visible.
