Those wheels are nice!
I've done a few thousand miles on size 225/50-15 RA-1 which are treadwear 40, "recommended for competition use only"
I drove insome rain, some cold(which is just as bad) and some dry.
A competition tire is dangerous when the tire is cold, and doubly as scary when conditions are cold/wet, or both. Paying very close attention, I found the RA1 to keep a high level of grip in the rain, after the tire was warmed up.
A buddy has a VW GTI shod with Azenis Sports. Testing the limits of adhesion is just as frightening in wet as with the RA1. Warmed up, the tire does very well. Cold and wet, just as bad as RA1.
Still, these tires are not optimized for wet use.
Most of these Track ready/auto-x type of tires have similar void ratios to allow for water evacuation. Falken is boasting the new design of the RT-615 and saying wet performance is greatly increased.
(The Falken brand has changed hands, from Ohtsu, who gave us the great Azenis Sport. Falken now falls under the Sumitomo banner, and Sears owns the advertising rights to the brand name Falken)Long story short, we need to drive on the RT-615 to see if it's up to snuff, because it has abolutely nothing in common with the Azenis Sport.
