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, for example.

This measurement is important to be sure you have proper wheel clearance. Learn to understand the common markings found on tire sidewalls. Windows 7 driver update. Solve problems related to tire size, wheel, rim, aspect ratio, width, circumference, diameter, speed, sidewall and speedometer reading.
Use this simple tool to quickly find the correct wheel adapters or wheel spacers. 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. 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.

Legend Offset: The distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline 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 centerline of the rim / tire assembly.
This will cause the tire to stick out away from the vehicle. H = High Positive or FWD (Front Wheel Drive) typically +45, 40, 35 offsets M = Medium Offset or RWD (Rear Wheel Drive) Typically +20 offset L = Low Offset or RWD (Rear Wheel Drive) Typically 0 offset 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. Torque: All alloy wheels should be installed using a torque wrench. This ensures that the wheels are not too tight or too loose.
Check your vehicle's manual for correct settings. When you install wheels for the first time, you should re-torque wheels after about 100km to 150km (60 to 90 miles).

Always refer to Owner's Manual for proper factory specifications that take precedence over the listed recommendations. 12mm = 7080, 7/16' = 5565, 1/2' = 7585, 14mm = 8595, 9/16' = 95115, 5/8' =135145. The bolt pattern, lug pattern, or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4, 5, 6 or 8 lug holes.
The bolt pattern is comprised of two numbers - the first indicates how many bolt holes are on the wheel, and the other describes how far apart they are. For example, a bolt circle of 5x108 would indicate a 5 lug bolt pattern in a circle with a diameter of 108mm. Dual Bolt Pattern: More and more manufacturers are building their wheels with two bolt patterns. This expands the number of fitments the wheel applies to.
For example: a wheel with a 4-100/114.3 bolt pattern has 8 lug holes and will fit both 4-100mm and 4-114.3mm fitments. Wheel Plus Sizing Plus sizing your wheel & tire combination was designed to enhance vehicle performance and looks by allowing fitment of larger diameter rims and lower profile tires. The theory is that while making these changes, you keep the overall tire diameter within 3% of the original equipment tires. This is important because larger variances can cause problems with transmission shift points which can decrease fuel mileage.
It can also confuse braking system computers which can even lead to brake failure. Here's the rule of thumb for 'plus sizing': Plus 1:. Increase section width by 10mm. Decrease aspect ratio by 10 points. Increase rim diameter by 1 inch Plus 2:.
Increase section width by 20mm. Decrease aspect ratio by 20 points. Increase rim diameter by 2 inches. Also of Interest.
