In reference to the Good Sam's experience.
Goodness, another reason I'm glad I live in the plains states. If it's round with just enough air in it ... they put it on. 80 - 85 is just aspect ratio or the width of the tire compared to the height. I think I would have asked for his 4 way tire wrench and proposed the guy go smoke his Lucky Strikes for about 5 minutes. Drag the spare from your car's trunk and stand it up next to your regular tire on the drive axle no less ...
