I got a new set of wheels for my road bike and will probably be moving my skinny tires from my fixie over to that bike. I want to get wider tires for the fixie, either 28s or 32s, to smooth out the ride a little. I've been riding this bike as a fixie since October and don't skid (at least I haven't managed it yet, and don't really feel the need). My riding is pretty much all urban, a fair amount of glass, not many goatheads.

I've been pretty happy with Schwalbe in general and am looking into either Marathon Pluses or Marathon Supremes. I know the basics- both have good flat protection; the Plus has better flat resistance but is heavier and has higher rolling resistance, while the Supreme is a little less flat resistant, has better rolling resistance, and is more expensive.

So does anyone have experience with these tires on a fixie? Any recommendations or things to beware of? Other possible choices? I want pretty good flat resistance because it's a pain getting that rear wheel off to change a flat (I had a couple when I first got the bike and was riding it as a SS).
