I have 19 Rial Luganos, stamps Made in Germany, and Hankook Ventus Evo II. I've hit a few potholes and I refuse to worry about issue associated with low profile 21s. 21s do look great though. I think the Hankooks are a great tire, and I ran them on my Acura.
I also think the the Rials (I got gunmetal grey with a Pearl White 70D) are a great deal and I think the "easily damaged" is a bad rap. Their 20s are coming out next month, but I'd by this same combo again. An infared picture of my tires did not show excessive heat towards the inside rears, although I do appreciate all he analysis lolachampcar has provided.
