tire width roll call - who else commutes on 23's??
 

700 x 23 here on my single speed, wouldnt have it any other way, who else is out there?

Aside from winter I ride on 23s. Wouldn't have a real problem with 25s.

23s mostly. Have put a 25 on the back for the subtle hotrod look.

700x22 on the front, 700x24 on the back of my fair weather bike.

700x25 (but look more like 23s) Gatorskins front and back of my rain and night bike.

23/25

I'm going to go wider once these tires are dead, just to see what it's like.

Went from 23s to 25s. Now I am running 32s and I am not sure I will ever go back.

Me too. For the most part I just rotate my tires from the race bike onto the FG commuter, throw in a Mr. Tuffy strip, and go.

For the most part, the city streets I commute on are in much better shape than the roads I train and race on.

I commuted for 2+ years on 700 x 23 Michelins, but Michelins tend to run wider than other brands. (Or at least they used to run wider.) For the past year, I've commuted on Conti 25s, which aren't any wider than the Michelin 23s but are taller. For my purposes, 23-25 mm tires are fine for commuting as the roads are paved pretty well on my route. I am more concerned about tire weight than width as my route has a lot of hills. I can't imagine lugging 32-35 mm tires up all of those hills.

23 front, 25 back.

I'll be rotating the back to the front soon and going 25/25.

I've ridden exclusively 700x23s for nearly 20 years, and now for the first time put some 700x25 Ultremo DDs on my brand new winter bike/commuter (Baron Outsider, review forthcoming). I'm not sure what I can say since the tires are on a brand new steel bike so I'm not sure if it's the tires, the frame or some combination thereof, but the ride is incredible. At some point I'm going to have to try out some 23s on the new bike just to help me sort out where all this comfort is coming from.

I need to get some digital photos, and then I'll write up my "Initial Impressions" review.

You may want to consider putting the new tire on the front. You always want your best rubber on front as it provides your stability in cornering and 90% of your braking. Also, sudden loss of air pressure on your rear tire is controllable. Not always so when it's your front tire.

28s, but there is 1/4 mile of my commute where I wish I had 38s

I found 25s to be the best.
Compared to 23s : Nice and cushy and harder to pinch flat when I get lazy about inflation.
Compared to 28s : Easier to get past the brake pads when changing wheels.

I run 21s on my tubular wheels. Those only come out on summer weekends, however.

23s all around. I've run 25s and 28s and prefer the smaller ones.

i have commuted 4 times with conti 23's but the streets here are pretty crappy and i switched to 25's. I found these more confortable and i didn't feel that I'm slower that before.

700x23

My new (used) fuji came with 700x23, but I am considering upgrading to wider, but i really don't know if I can fit anything wider once I shove my fenders in there.

No.
406/35 front, 559/40 rear.

I like going fast. 23s most of the year when I can get home in daylight. Roads here are too raggedy to roll my road bike after dark. I don't like crashing or tearing up wheels.

Used to do the road bike 23's (tubulars when I was in college) routine until I found that a combo of comfort + speed suits me better than pure speed (hmmmm....... about the time I hit 40.......). 28-32 is my ideal range these days - my 23 days are over (happily).

It's more like 70% of your braking. That's still a lot - the back would only do 30% then.

I'm good with any tires 23c-28c.

I ride on 23s Michelin Dynamics currently. However I will likely switch to 28 only because my route summer route includes going through crush gravel. Just not sure if the 23s can hack it. I'd get 32s but I may have brake and fork clearance.

700x35 here... smooth and comfy

Lately I have been riding my road bike to work.

700 x 23mm Tubulars, yeah!

23's here... once the snow is off the road that is.
