I do like the wider tires.

My Trek 400 came with 700c x 28 tires. I had been riding it with 700c x 32 absolutely fine. Because I wanted to use a particular brake set, I put on some 27" tires- I started with 1 1/4, but they were too tall for the fork crown, but had clearance at the brake bridge- I just settled on 1 1/8" Paselas.

My Trek 730 would not fit 32s- I had room at the fork crown (barely) but they rubbed on the brake bridge. Settled for 28s on that one.

Not that this pertains to anything in this thread- the "Swift Tire Sand Canyon" 1 3/8" tires look really great- I'm going to get a set, just because the only 1 3/8" tire I've ridden was 30 years old and I didn't trust it.
