I've got a set of Potenza RE750's right now in 225/50/16, and I must say that I like them very much. They provide good grip and road feel for my style of driving, and the wet traction is excellent. Good durability too. The ride is a bit rougher and louder than the RE92's though, if it matters. Overall, I like them. Others say that their grip isn't good enough, but that's when you use them on the track or for Auto-X.
