I dont remember the thread you are talking about but I always go to TireRack.com for information like that.
Just type in your size, click on any tire it doesn't matter, then click the "Specs" Tab. It will give you all sorts of information about the tire and all the other sizes available! Geat Resource!
They will tell you the Uniform Tire Quality Grade(UTQG), Max Load, Max Inflation Pressure, Tread Depth, Tire Weight, Rim Width Range, Reccomended Rim Width, Sectional Width, Tread Width, Overall Diamater, Revolutions per Mile, and Country of origin.
I work for another big name tire retailer but I still tend to look at tire rack when doing personal research because there database is quite a bit more user friendly and gives the customer more information. Lucky for me they charge shipping or their prices would be really competitive
