Want a performance tire that is also very good in the rain.
Neither of the ones you mentioned are very good in rain.
Study Tire Racks wet braking distances from 50 mph to gain clues.
good wet performance is the hardest and most expensive parameter to obtain.
Warning most tires are designed to peak around 8,000 miles and slide down the slope thereafter.
If rain performance is really desired you must be prepared to replace tires when half worn!
Sure you really want good rain performance?
The RSA outperformed the Solus 105 feet to 112 feet from 50 mph, a REAL WET Performance tire can stop in 85 feet in an identical test!
