The bolt pattern for a 2009 Lexus IS 250 is 5x114.3 (or 5x4.5 ), indicating that each wheel has five bolts (or lugs) that are arranged circularly with a 114.3 mm (4.5 inches) diameter.
One of the simplest yet cool 2009 Lexus IS 250 mods is to replace stock wheels with bigger aftermarket options.
However, before you switch, you must know your 2009 Lexus IS 250 lug pattern to confirm compatibility with the new set of wheels. But even if the current bolt pattern of your 2009 Lexus IS 250 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 2009 Lexus IS 250'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.
