Can't beat the Sotto 3 285s at $155 each!
I was going to get the Sotto S2 275s for the front anyway but the Tire Rack sales guy told me running Sotto 3 285s on the rear and Sotto S2 275s on the front was a bad idea. Probably bullshit but I decide to go ahead with 4 285s. If something seems off I'll get 275s for the front and just stash the extra rears.
I bought (practically) new 706M bi-color rims for the winter setup.
