Re: Measuring For Wheels Video,...

This is a great thread from Car Craft.
http://www.carcraft.com/techarticles...t/viewall.html

It also shows you how to make a quick tool for measuring.
The back wheels can be done easily with a tape measure and a straight edge.

The front is a little more complex, because they have to turn.
The tool in this article allows you to rotate the rotor to check for interference inside the entire fenderwell, AND, turn the wheels left and right to check for chassis interferences.
This is a must for static dropped and bagged trucks, as well as getting a proper fitting wheel on stock trucks.

As most know,... the track width of the rear wheels on the 60-87 trucks are narrower, than the front wheels.
If you run the same width wheel (front and rear) it is obvious, by just looking at your truck.
The front wheels are closer to the fender edge than the rear wheels.
Altering the backspacing or using wider rear wheels, will help mask this issue that GM designed in these trucks.
