I did some searches on alignment and found some references, but would like to confirm.
Is the proper front end adjustment for alignment 1/8" toe-out (front of the wheels 1/8" more apart than rear of wheels). This is done with the track rod adjuster link, correct?
Also is it cool to just measure identical marks on the tires front and back. |

1/8" toe OUT
Yep - adjusted with the track rod (behind axle)
Pick a line in the tread pattern, measure width in the back and then 180 deg around in front on the same point in pattern, adjust as necessary
Oh yeah - do it with the wheels on the ground with full weight (ie: not on stands or on a jack)

this may be a really stupid question - but does it matter what size tire you have (i.e. more rubber = further from center = more than 1/8")? |

You're measuring from "same place on pattern" to "same place on pattern" (front and back) - tire width doesn't play into it since you're not trying to achieve a fixed dimension - only 1/8" toe out.

well to answer your question yes tire width does effect the best toe setting.
once you start going wider then stock most vehicles need a little more toe-in to keep the tires from grabbing groves in the road.
jeeper meats will need more then skinny pizza cutters |

Bill and musky...
But I think Marc's question isn't in regards to width, but to the diameter....
If 1/8" out works for the stock size tire, ie, a 29" diameter tire, then if you had a 32" diameter tire, that fraction should be bigger than 1/8" to maintain the same angle to keep the same amount of toe.... right?

i think diameter negats its self as you go bigger the tire will track better because the circumfrence getts bigger hence covering more ground in one revolution and not being as grabby making toe in/outnot as important.
??? i think I better go check this??? |

That sounds logical musky. What I think will be the key here is that we're not using some sophisticated optical equipment (other than our eyes) to do this with. So while computer alignment may come up with tenth of a degree difference between the different tires (narrower vs. wider), in practical terms it does not matter that much.
Even with computerized alignment machine the techs use the rims to attach the sensors (I forget what they call the "alignment heads"). This means the toe-in/out angle will be the same regardless of the tires. However, the better techs always say: "Let me give you a hair more toe-in since you're running wide tires". So in the end my alignment is done by "gut feel" anyhow. Yet I paid for the use of the computer.  |

I was refering to diameter not width |

I guess all I have to compare is my own situation and with three different tire sizes (stock - 245/75 - 235/85) - alignment has been fine (both road feel and tire wear) with 1/8" toe out on all sizes.
Obviously I cannot speak for the "jeeper meats"
