I have used this combination for 6 years and am very happy with my choice. I get about 16 - 18k from the front running at 42 psi and 10 - 12k from the rears running at 40 psi. I do a combination of super slabbing and secondary roads at a moderate pace. Keep an eye on your rear because when they do wear out, it happens very fast, especially if they square off. Ride is very stable and dependable and there are no surprises when it rains.
