I live in the mountains, my girlfriend and son live in the mountains - simply put, LOTS of turns. That stated, California has had a pretty hot winter - so it’s about time to switch from my Nokians to all season. I’m looking for ultra performance all seasons with the highest amount of grip possible. I chose Nokian because they were so highly recommend - so I look to you guys for help with my A/S, I burned out my summers in about 15k miles. Thanks in advance.
