It was actually 42 up front, and 32 on the back. Until yesterday. Now it's 32 front and rear... Both Bontrager Race Lites...
Partswasher and I agreed on the larger front thing - you want the more cushy tire there. True, you have to lift higher to get over a curb, but you also have more give from the tire and tube. It's more comfortable. You don't want your larger contact patch on the back where it increases the drag. The front is pretty much just along for the ride.
I'm going back to the 42 next winter, possibly with some DIY studs. But the last 24 hours and a very few miles without the knobbies up front, I'm thinking my summer setup on the commuter is done...
