5 X 4.75 Bolt Pattern Measurement and Specifications
The 5 X 4.75 Bolt Pattern or Pitch Circle Diameter (PCD) is made up of the stud count (5) and the bolt circle measurement (4.75), the notional circle determined by the center position of the studs.
How To Measure 5 Lug Bolt Patterns
Measure 5 lug wheel bolt patterns from the outside edge to center distance between two studs that are across the hub from each other. This measurement is your bolt pattern diameter. Learn more about wheel dimensions below.
Alternate 5 Lug Bolt Pattern Measurement
Note: When measuring a 5 lug wheel with a tape, the measurement is only an estimate unless measured using a wheel bolt pattern gauge, although double-checking with this alternate method below can help ensure accurate results.
Alternate 5 Lug Measurement: 2 3/4" Center to Center = 5 X 4.75 Bolt Pattern.
What Vehicles Use Wheels With 5 X 4.75 Bolt Pattern?
The 5 X 4.75 bolt pattern is common to CHEVROLET, PONTIAC, CADILLAC, OLDSMOBILE, JAGUAR, BUICK and ISUZU vehicles. A full list of vehicle makes and models appears below.
5 X 4.75 is generally thought of as the 'Chevy Bolt Pattern', or General Motors (GM) passenger car bolt pattern.
Bolt Pattern Torque Sequence / Specifications:

|Stud Size||Typical Torque Range in Ft/Lbs||Minimum Thread Engagement (turns)|
|12 x 1.5 mm||70 - 80||6.5|
|12 x 1.25 mm||70 - 80||8|
|14 x 1.5 mm||85 - 90||7.5|
|14 x 1.25 mm||85 - 90||9|
|7/16 in.||70 - 80||8|
|1/2 in.||75 - 85||8|

It is prudent to re-torque wheels after about 60 to 90 miles (100km to 150km) of driving. Learn more about lug nuts and torque.
Hub Center Bore
Hub Center Bore: Relates to the center hole in the wheel that centers the wheel on the hub of the car. Since most wheels are mass produced, they have a large center bore to accommodate several different vehicles. If this is the case, it is recommended that you use a hub ring. Hub rings are hard plastic or metal ring that fits between the wheel and the vehicle. This centers the wheel perfectly on the hub ensuring that there is no run out when the wheel is installed on to the vehicle. Without hub rings it is possible to get vibrations even if the wheel / tire assembly is perfectly balanced.
Wheel offset is the distance from the mounting surface of the wheel to the true center line of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true center line of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true center line of the rim / tire assembly. This will cause the tire to stick out away from the vehicle.
H = High - Positive Offset, typically FWD (Front Wheel Drive) +45, 40, 35 offsets
M = Medium - Neutral Offset, typically RWD (Rear Wheel Drive) +20 offset
L = Low - Zero to Negative Offset, Offset typically RWD (Rear Wheel Drive) 0 offset

Additional Wheel / Measurement Information
Key Identifying Wheel Dimensions: Wheel Bolt or Lug Pattern (or bolt circle, lug circle, lug pattern, etc.) is the measured diameter of an imaginary circle formed by the centers of the wheel lugs or bolt holes. Bolt patterns can be 3, 4, 5, 6, 7, 8 or 10 lug holes. A bolt circle of 5 x 4.5 would indicate a 5 lug bolt pattern on a circle with a diameter of 4.5 inches.
There are four important measurements that are used to categorize and identify a wheel for fitment purposes.
- Rim Diameter The actual diameter of the wheel at the point where the tire bead seats (NOT the outer lip of the rim).
- Rim Width Measure from the inside of the outer lip at the bead seating point to the inner lip.
- Back Spacing From the inside of the wheel at the point where it contacts the hub, brake drum or axle flange to the inside edge (lip) of the wheel.
- Bolt Pattern The measured diameter of an imaginary circle formed by the centers of the wheel lugs or bolt holes.
How To Measure Wheel Bolt Pattern
If there is an EVEN number of lugs: Measure center-to-center on lugs directly across from each other.
If there is an ODD number of lugs: Measure from the CENTER of one lug to the OUTER EDGE of the hole diagonally across from it.

- Tire Size Change / Speedometer Calibration Calculator This calculator is designed to give information related to tire size changes and the general impact they have on the calibration of a speedometer. It determines speedometer error and tire size information based on published and generally accepted tire dimensions as given by the standard US tire system (i.e. 205/45-ZR16). All calculations are based on the assumption of a new tire (as opposed to used) where the numbers on the tire accurately represent the dimensions.
