I just noticed the RE950 was H-rated. I'd skip that one on a 45 series tire. I bought H-rated tires just once and they did not fit my driving style. They handled like crap and lasted 15k miles. That was a different car, but the KDW's last a lot longer and have higher grip.

I think Luke usually recommends the RE930 as the best value in hi-perf summer tires.
