I ran these on a previous car, and I compared them to a Toyo T1-R, head to head on the same car, and liked them more than the Toyos. The best part is, they were way cheaper than the Toyos. However, I didn't keep the car that long afterwards, so I can't compare as to whether they would have stayed quiet (performance tires tend to get more noisy when they wear), nor how long they would have lasted compared to the Toyos.
1KULSOL, why 255/45/18? Odds are at that extra width, a 45 profile, and an 8" rim, you're probably getting less contact path due to the bowing of the contact patch of a 255 on an 8" rim. I'm assuming you're on stock wheels that is.
