Runner42, I'm so glad to hear from someone that has run these tires. When I first heard about them, I'd never heard of them and had my doubts. But when I did some research, everything came back very positive but I didn't see any feedback from 4runner owners. The one thing I'm most amazed about, is their smooth road riding ability. They area quite, ride very smooth and handle like a real road specific tire. Very impressed so far, thanks for your input!
