I have these tires for almost 2 years. I live in Seattle, so I have to deal with the mist and rains in the area. They do fairly well in the rain, as I have a APR stage 2 Audi A3 with 300lb torque. You have to be extremely careful when spinning these tires, because the chunking of these tires are quite bad. On the sidewalls of the tires, I start seeing pretty bad chunking after 20k miles, I am struggling on what tires I should get for my next set. But anyways, if you want good tires under heavy rains, these ones will do, they are just not for drivers like me.
P.S. the noise is getting terrible.
