ASSEMBLY INSTRUCTIONS
-
Assemble the extensions and tire clamps as shown but leave the wing nuts loose.
Repeat for the other assembly.
-
Below is a chart giving recommendations for wheel width compared to tire width. Using a tape measure set the desired wheel width and tighten the middle wing nut. Repeat for the other assembly.

-
Install the extensions onto the tire 180 degrees from each other. Slide the tire clamps against the tire and tighten the wing nuts. Remove the center carriage bolts and wing nuts after the clamps are tight against the tire.
-
Assemble the center section as shown below at your desired wheel diameter.
-
Insert the center section at an angle and rotate until perpendicular to the extensions.
-
Insert the carriage bolts and wing nuts attaching the center section and the extensions. Slide the center section to your desired backspacing and tighten the wing nuts. Measure from the inside of the tire to the edge of the WheelWise™ Tool on both sides to ensure it is centered in the tire.
-
Support the vehicle with jack stands. Install the WheelWise™ Tool and tire assembly onto the vehicle. Check tire and wheel clearances by turning the wheel left to right and raising and lowering the suspension. Adjust the backspacing as needed to gain proper clearance.
-
Once you have gained proper clearance remove the assembly.
Note the following:
i. Bolt Hole Pattern (Etched on the hub mount plate)
ii. Wheei Diameter (Etched on the angles)
iii. Wheel Width (Dimension from step 2)
iv. Wheel Backspacing (Measure as shown on page 3)
Example:
Taking our sample 9 inch wheel width measurement from the tool and adding 1
inch to account for wheel flange thickness, our overall wheel width is 10
inches. This makes our wheel centerline dimension to be 5 inches (10 divided
by 2= 5). Measuring the backspacing as indicated above, we have a measurement
of 5-3/4-inches. At this point we’ve taken two simple measurements and we have
everything we need to calculate offset with some simple math.
Formula:
Backspace – wheel centerline = offset
Any fractional answer ( the 3/ 4 in the backspace) needs to be converted to a
decimal equivalent by division first.
3 divided by 4 = . 750
Our wheel sample: 5.750 – 5 = .750-inch
However, since offset is stated in millimeters, we have one more calculation
to run. There are 25.4 millimeters in an inch, so multiply your answer from
your first formula by 25.4 to obtain your offset in millimeters .
750 x 25.4 = 19.05mm positive offset
(wheel mounting surface towards the outside of the wheel)
If the backspace measurement is smaller than the wheel centerline measurement,
your offset would be negative (wheel mounting surface towards the inside of
the wheel}.
The deeper, more concave appearance you want in your wheel face, the more
negative your offset needs to be.
Conversely, a more positive offset will provide for a flatter wheel face
appearance. Finally, know that a positive offset provides for more
backspacing, while a negative offset reduces backspacing.
