We had our first rain yesterday and while driving in my Toyo's (3000 miles on them) and my 20", I was slipping and sliding through a pretty tight cloverleaf turn. This is my first experience with this setup in the rain and was not too happy about it. My Michelin's with 18" wheels felt much better through this turn in the rain before. I am hoping that this is because it's the first rain and the roads are more slippery. I will wait and see, makes me want to put my 18" back for the winter!
