I have had a couple of instances lately where my roadster starts to fishtail and jaunt side to side like I'm on a sheet of ice. Last week it did this with some light snow and slush so I chalked it up to ice-like conditions. Today, I drove in some moderate rain and same experience... driving speed limit on highway and a sudden shift of the car to left and right. It wasn't a major shift like I was going to do a 360 but enough and sudden enough that it's a scary feeling. I let off the pedal instantly and dropped to 40mph, which helped but still gave the occasional shift. I have 6 month old tires on the rear and likely the original tires on the front. Both front and rear are the Yokohama Neova. And, after checking the tread, I just noticed how the fronts have a ton of tread remaining and the rears are bald! I recall a thread about rear tires lasting not so long, guess I just figured it out first-hand. I'll do some forum searching and looking for recommendations on best all-season tires. I am not looking for performance tires.
