Number range

Is there a rider weight in which one should go from a 23mm to 25mm tire?
There are too many variables to state a specific number, but in the general advice category, something in the 160-170 lb (73-75 kg) range, there should be no problems with 23 mm. Over 200-210 lb (93-95 kg) most people would do better on 25mm or wider. You will get opinions outside these ranges, and that's where the "too many variables" come in.

I'm currently 194 pounds and have ridden 23mm's for 26 years. I think I will try 25mm just to make a comparison. Sadly with the price of high end tires it's not something to casually try.

I'd say if pinch flats become a concern before handling does, as you try lower pressures for a comfortable ride, you should be on a fatter tire.

You will like 25's.

I am a pretty big guy - 6'4" and over the years my weight has been as low as 196 (when I was in my racing prime :)) and, uh, much higher. For a long time I rode 23's pumped up to about 120psi with no big problems.

Quite a few years back I was away from home and had a tire get destroyed on a training ride. I went to the local shop and they had the tire I was looking for (Vredestein Fortezza) but only in 25's. Given the immediate need (I had a race the next night) I bought a set and off I went. No big difference that I could notice for a few weeks.

My big revelation with the wider tires is when I figured out I could drop the tire pressure quite a bit and still not get pinch flats. I could ride the 25's at about 105psi which was a major difference in perfromance - no more jackhammer ride, better grip in corners and in the wet, it was a huge deal.

So if you made it this far thhrough my story, I don't think there is a good guideline to use for weight vs. tire width because most heavier riders up the pressure as a preventitive measure (and also because the perception is that the rock-hard tire is faster). If you can change some of your habits, you will get more benefit from wider tires regardless of how much you weigh.

FWIW, I now run the largest tires I can fit under my fork crown (28's @ 90-95 psi) and couldn't be happier.

+1000 on going from 23's to 25's. Just made the switch myself the other day & took 'em out in my group ride on Tuesday night. Probably won't ever go back to 23's if the other night is any indication. I bought the Specialized S Works Roubaix Open Tubular tire and loved the feel of the tire. Would HIGHLY recommend going to a 25.
