### Rear Toe In - again.

Posted:

**Mon Oct 24, 2016 11:22 am**With all the different tyres and wheels I cannot see how having a toe in measurement in inches or mm can be particularly accurate.

Using a specific angle would remove this problem??

My car has 175X70 / 13, which according to a comparison site, has an OD of 22.6 inches. Assume that is the hypotenuse. Small side opposite the toe angle to be 1/8 inch (0.125) for this exercise.

0.125/22.6 = .00553 inverse sine = 0.316 degrees. Call it 0.32.

Therefore the recommended toe in by Spyder being 3/32 per side would give an angle of 0.24 degrees per side.

Is this nonsense?
