I instated Revo 2's on my trunk - not so much that I needed AT capability, but I liked the look and had previously been happy with the original Revo on another vehicle. At 26000 miles I had to swap because I was losing grip too often (on the road). I had installed Alenzas on my wife's '10 4Runner so decided to skip the aesthetics and purchase an adult tire. Driving off the Firestone dealer lot, immediately I noticed a smoother ride and a perceived lesser rolling resistance. After two weeks, I can confirm both. Now, had the Revos -in their excessively rapid wear - gotten that bad incrementally without me being aware? It's possible. What I know now is the ride of my truck is much nicer. Will that translate to picking up another .5-1mpg or so? Maybe. I must admit the Alenzas do exhibit a little tire whine, most noticeable when slowing down. Not louder than the Revo but high-pitched and different. And they look ok too - for an old man (53).
