Welcome to True Laser Track - the MOST Accurate Laser Alignment System

Measuring the toe:

Measuring toe is only done using the Right Front and Left Front True Laser Track. You already have your four tape marks on the floor; you will move the targets to the very most forward Left Front and Right Front tape marks and then move the next two targets to the 14’ tape mark that is behind the Right Front and Left Front hubs.

Go to the True Laser Track on your Right Front hub, rotate the laser up to the front target, level it off and center the beam up on the front target. This will establish the Right Front dimension. Now you will establish the Left Front dimension, rotate the Left Front laser to the front, level it off and center the beam on the target. You just established the Left Front dimension. You’ve projected your dots forward equal distance from the center of our hub and established our measurement. Your dot is on the center of your scribe mark located on both targets. Just follow it down, using the same name brand, good quality tape measures and measure the total length between the right front and the left front target laser dots. Now we head to the Front rear measurements.

Take those same True Laser Tracks that are on the Right and Left front hubs and rotate them both to the rear targets ( the targets that are located at the 14 foot tape measurement) and level them off. Your dot is on the center of your scribe mark located on both targets. Just follow it down, using good quality tape measures and measure the total length between the right rear and the left rear target laser dots. Look at your difference in dimensions. We have 84 ¼” for our front dimension, your rear dimensions are 84”. The difference in dimensions between the front and the rear targets over a 28” span are a ¼”. (84 ¼” in the front and 84” in the back.). Our wider dimensions are in the front. We haven’t adjusted the right side; we’ve only adjusted the left side. We’re going to toe out the left front. If we’ve got .250(¼”) (we’re doing this in thousandths), we divide that by 336, which is the number of inches in 28’. It gives us the number of thousandths of an inch, per inch, which is .0007. Now we just multiply by the diameter of the tire. It’s a 26” tall tire; it gives us 20 thousandths toe. That’s the measurement you are looking for

FORMULA: Difference between the Front & Rear measurements (in thousandths)
divided by the distance Target to Target (in inches) multiplied by the tire diameter equals the toe

The “B” measurement is the top line on this chart. Please refer to the photo to figure your “B” dimension. The “B” measurement is the difference between the rear widths of the targets subtracted from the front width of the targets. To start… find your “B” measurement, scroll down till it intersects with your “A” measurement (the “A” measurements are on the left side of this chart). See photo to figure out your “A” measurement. Where they intersect is your TOE. This chart is based on a 27” tire dimension; your math on different sized tires will vary (see math sheet to refigure) Are You Ready To Start?
