Wrenchbender/Fla54chevy3100,

Can you elaborate on an "easy" was to measure toe-in? As I understand it, that means that middle/center/front part of the tires are 1/8" closer together than the middle/center/rear part of the tires. It's pretty easy to tell the middle of the tire by looking at the grooves in the tread. Unfortunately, you can't simply measure the direct line distance between the middle/center/rear point of the tires since part of the truck is in the way (at least in my 49 1/2 ton). If you measure lower than the midpoint than the measurement is thrown off by camber. Is there an easy way to measure the rear of the tire I don't know about? (I've been thinking about using a plumb and marking two dots on the floor to represent the middle/center/rear part of the two tires and then measuring the distance between the two marks).

Thanks
Dave
