1999 Buick Riviera Bolt Pattern Guide By Years
Select a year
The bolt pattern for a 1999 Buick Riviera is 5x115 (or 5x4.52 ), indicating that each wheel has five bolts (or lugs) that are arranged circularly with a 115 mm (4.52 inches) diameter.
One of the simplest yet cool 1999 Buick Riviera mods is to replace stock wheels with bigger aftermarket options.
However, before you switch, you must know your 1999 Buick Riviera lug pattern to confirm compatibility with the new set of wheels. But even if the current bolt pattern of your 1999 Buick Riviera and the new wheels do not match, consider converting to the required scheme using the wheel adapters.
Also, new rims must sit within the wheel offset range, and the 1999 Buick Riviera's stud must fit onto the hub bore. Use the measurements below while searching for new wheels.
A bolt pattern, or lug pattern, is a two-number system used to measure the imaginary circle (PCD) formed by the lug holes at the center of a wheel. The first number counts the holes in the wheel, while the second number indicates the pitch circle diameter in mm or inches.
Measures the distance from the hub mounting surface to the center of the wheel. It is vehicle specific.
A machined opening in the center of the wheel. It must be "Hub Centric" to reduce vibration.
The outer diameter of your wheel stud threads in either metric (M12, M14, etc.) or standard units (1/2", 9/16", etc.).
Dimensions of the stock tires, including its width, aspect ratio (sidewall), and diameter.
