At least I think its new: More and more alignment equipment is using degrees and minutes for specing toe during an alignment. Thats good because the angle doesnt change with the diameter of the wheel / tire. BUT...determining the desired angle doesnt see to be so simple. Does anybody know what 1/16" - 1/8" equates to for a 26 inch tire on a 15 inch rim? So far I THINK 14 minutes or about 0.25 of a degree equates to 1/16" Anybody gone down this road?

I've always used degrees instead of inches when I do alignments. I guess its what I got used to years ago. But anyway, every 1/32 of an inch of toe is 0.12 degrees or 7 minutes. Should get you close. Edit..I just looked it up on my machine at work and 1/16 =.13°

Could someone explain what you mean by 'minutes'? Please.
I can't afford this.

For every degree there are 10 minutes. So .5 minutes is 1/2 degree
DUH...Your right I was thinking of tenths...Not enough coffee.

I just drew it out on MasterCam and you're very close, .25 degree comes out to .0568 inches or just a nick under 1/16

I almost missed this thread, thanks for the explanation of minutes. I've never heard of minutes and seconds used for any measurement other than time. Tick. Tock.

I'll bet you have, just didn't realize.
Used in Navigation, depending on the "format" of the figures
Used in expression of bullet path (I'm sure you've heard the term "minute of angle" re: shooting)
Here's about KREM channel 2 tower location in Spokane:
47° 35′ 40.9″ N, 117° 17′ 56.8″ W
The first is degrees of elevation from the equator, which is zero degrees, 90 being the N pole, so the tower (near Spokane) is 47 degrees, 35 MINUTES, and 40.9 seconds toward the N from the equator.
The second half, is east - west, so 117 degrees 17 MINUTES and 56.8 seconds west of the 0 degree longitude point on earth which is called the Greenwich meridian. This is an arbitrary point on earth that is designated as being the zero degree point, and dates back to the early days of navigation, Europe being the "important" area at the time.
Google longitude, latitude, "prime meridian," "Greenwich Meridian" and have a day.

A good toe in will be about 1/4" toe in.. The reason for the toe in is that centrifugal force will put it at zero when you are going down the road.. Don't know about the degrees..
1/4" toe will KILL a set of tires. 1/8" MAX toe in.

I've never understood why toe was not ALWAYS in degrees.
Cuz when your pitted out in the south forty where the track lights don't shine, you wacked the lead car in the last heat race, and bent a tie rod and you need to get it replaced and buttoned back up before the main, and you've got a flashlight and your working in the dirt, you whip out the tape measure and jack stands and get to it.

I can assure that when Ma "wrote the books," there was no thought of you being in that condition
