Mazda 6 wheel bolt pattern
Direct answer for the 2016 Mazda 6
The 2016 Mazda 6 uses a 5x114.3 mm wheel bolt pattern. This is sometimes written as 5x4.5 inches in imperial measurement. The specification applies to factory wheels across the standard 2016 Mazda 6 sedan range, including the Sport, Touring, and Grand Touring trims. It does not change between the 2.0-liter and 2.5-liter gasoline engines available in most markets.
What the bolt pattern means
The first number, 5, refers to the number of wheel studs or bolt holes. The second number, 114.3, is the pitch circle diameter, or PCD. This is the diameter in millimeters of an imaginary circle passing through the center of each stud or bolt hole. A 5x114.3 pattern means there are five holes evenly spaced on a circle measuring 114.3 millimeters across.
Other wheel fitment specifications
The center bore for the 2016 Mazda 6 is 67.1 mm. Factory wheels are hub-centric, meaning they center on the hub using this bore rather than relying only on the lug nuts. The factory lug nut thread size is commonly 12 mm x 1.5 mm for this generation. When replacing wheels or lug nuts, the thread size and seat type must match the hardware already on the vehicle.
Why the measurement matters for wheel changes
A wheel with a different PCD will not mount safely even if the lug hole count is the same. For example, a 5x112 wheel from some European vehicles may appear close, but the bolt circle is different. The lug holes would not align properly with the studs. A 5x114.3 wheel from many Japanese and North American vehicles is required for the 2016 Mazda 6 unless an adapter is used, which may not be legal or safe in all regions.
Checking before buying replacement wheels
When buying aftermarket wheels, confirm the bolt pattern, center bore, offset, and width as a set. The bolt pattern alone is not enough to guarantee fitment. A wheel with the correct 5x114.3 pattern may still contact the brake caliper or suspension if the offset is wrong. The 2016 Mazda 6 accepts a range of factory offsets, but aftermarket wheels should be checked against the specific trim and brake package.
Measuring the bolt pattern if uncertain
On a five-stud wheel, the bolt pattern can be measured from the back of one stud to the center of the stud two positions away. For the 2016 Mazda 6, that distance should read approximately 114.3 mm when measured correctly. In imperial terms, it should be close to 4.5 inches. A measuring error of a few millimeters can cause confusion with other patterns, so mechanical verification is useful when documentation is unavailable.
Rotating and maintaining factory wheels
Because all four wheels share the same 5x114.3 pattern, standard tire rotation patterns can be used on the 2016 Mazda 6. The owner's manual for this generation typically recommends a regular rotation interval. When reinstalling wheels, the lug nuts should be tightened in a star pattern to the manufacturer's specified torque. The bolt pattern itself does not determine the torque value; the thread size and vehicle specification do.
