After much thought and research, through customer feedback, advertisements and testing reviews I chose these tires for their decent ratings, price and size. My car, Lexus SC 430, comes with 245/40-18 tires wearing low profile tires which I didn't find a comfortable combo, especially for a Lexus GT. I decided to purchase a set of used LS430 wheels which share all the specs of the 18s, offset and hub size. The Hankook 235/50-17 Ventus V2 Concept, (26.1 in. dia.) gave me .7 inch more sidewall height, close to the same tread width and only .4-inch larger diameter. Hankook has several 235/50-17s with 26.1-inch diameter which is .2 inches smaller than most 235/50-17 tires, usually 26.3 This combo gave me a smoother, more comfortable, by at least 60%-70%, and quieter ride. I always keep my tire pressure to near spec. 34psi front, 31psi rear and they perform great dry, good wet and good cornering. I don't drive in snow so no comment there. I feel they are much a better wheel and tire than OEMs.
