Bought a set for my all-purpose driver, primarily due to pricing. I use Michelin PSS and Bridgestone S04 on my other cars (AMG C63 and BMW M3 respectively), and comparatively, the Indy 500's have excellent grip and behaviour; very progressive and excellent communication at the limit. Wet performance is excellent. Noise and harshness (impact on road imperfections) is higher than others, but not enough to offset the pricing. This car is hard on tires, due to it being front drive and a high-boost engine tune, so tread life is important. After about 4000 km, no noticeable wear to date.
