Wanted a taller and wider A/T tire. I just got them mounted; only have 30mi on them. They're quiet at speed but have more sidewall so a bit more roll in the twisties than the Firestone I had on when I bought the truck. It's at stock height front and rear and there is no rubbing at all in the tight turns. I'll be taking it across the country and look forward to see what if any change to my mpg I'll experience.
