Let's start over......
for clarification, the series number (second number) is a percentage as you already know, but its not what most people think. If you took the tire, cut a section out of it and laid it out flat, then the percentage is how much is sidewall. Its kinda hard to explain, like bead/sidewall/tread/sidewall/bead both of those sidewall numbers combine for the series percentage number.
Patrick, I now have no idea why the dealer guy thought they could not get their equipment on the wheel with out scratching them, unless their equipment mounts totally different. This was a Jim Bean alighnment machine. The thing monted exterally on the edge of the wheel, dig not need to "grasp" anything. They used bunge straps to secure it to the wheel. Sure is great to not be pulling and darting around now.

I got a pic of the truck on the rack when they changed out the tires, you won't believe how they had it balanced in the air. That scared me. Had a small block of 4x4 under the pumpkin.
Blue, this guy is getting a bit belligerent... I would keep an eye on this thread if you guys are not already

50 series tire
outer bead
outer sidewall 25% (of the rubber bead to bead)
tread 50%
inner sidewall 25%
inner bead
40 series tire
outer bead
outer sidewall 20%
tread 60%
inner sidewall 20%
inner bead
correct its a percentage of actual rubber bead to bead across the tread, so it would be

Yep, I think you are correct. The wheels were a lot more at risk during the tire mounting than the alignment.
