No source of answer, just my knowledge of how tires are sized and the engineering background I have.

Nice numbers. Got those too. I would have approximated to the 4th decimal place though :-)

Actually I could only use three signigicant figures. My bad. I used 25.4mm/inch so 3 is my limit. Ive been out of college for a while so I guess I screwed up.

I'm gonna try to work this out in the space here. Let's try the 255/65/16. I just secured the valedictorian spot and got into UCLA and Harvey Mudd, so hopefully I do it right:
255mm=25.5cm }
}====> (Same as Marks 25.4mm/in)
2.54cm~1in }
just >10 in across
>10*.65=even closer to 6.5
6.5*2+16=29
29*pi~93, say 90
90 in = 7.5 ft
5280/7.5=very close to 700
Your numbers look good to me. But more importantly, it looks like I did it right...hehe.

3) Altitude concerning:
a) barometer pressure
4) Depth of tread

I think Mark has the better numbers here, sorry. Lower tire pressure would indeed make the tire have to go around more times/mile, but since the size was all we have to go off of, I think his are right. How did they actually calculate that anyway? Empirical?
