Well, apparently the rating system is not absolute. In other words, "740" does not equal "80,000 miles," etc. It is supposed to be a methodology to allow the consumer to gauge the relative tread life of a tire. In other words, one can expect a 320-rated tire to last longer than 140. 560 should last longer than 440, etc. Many tires, like studless ice/snow tires and ultra-high performance tires, do not even list such ratings because their life is so dependent upon road conditions. A set of Blizzaks might last 30-40K miles on icy roads, but only 15-20K on dry (or mostly dry) roads... even less if the ambient/road temperatures are very warm.
 
The 740 on the TripleTred is the highest I've seen. One of the other posters on Carspace, ruking1, claims over 100,000 miles on tires he has owned, but I do not know how highly the tires were rated for treadwear. He has a specific method for "breaking in" the tires and takes it pretty easy on them when driving.
 
I think one major factor for tread longevity is the time over which those miles are accumulated. If you run a set of TripleTreds at 4-5,000 miles a year, you will likely have to replace the tire long before you hit 80,000 miles. There might be tread on it, but the rubber compound is likely going to be so aged that performance is severely diminished, as well as sidewall integrity.
 
I have a set of tires on my '69 Chevy that were installed in July 1997. I have about 40,000 miles on them, and they have tread left, but they really need to be replaced.
