I *wanted* to try the two-size-up from OEM on my SW2. However, whenever I researched the tires, the one-size-up was usually 1 lb more, but the two-size-up was always 3 or 4 more lbs. One-size-up nets me a 2% gain, but two-size-up would have netted me a 4% gain.

It still nags the back of my mind that I haven't done the two-size-up, but the problem with tires (for me) is that you just can't swap 'em out on a whim. Once they're on for me, they're on for 50K+ miles.
