As my current tyres are virtually worn through I'm considering moving to something more comfortable for the commuter bike but I'm not sure what I can fit in the frame/mudguards and all the tyre sizes that companies quote are at best guesses in my experience.

Is anyone running continental (or maybe other makes) 28 mm tyres? could you measure the width and depth for me?

Thanks,

Gethin.

I just installed 28c Gatorskin's on my Trek hybrid. These tires are a bit lighter than the 38c though I noticed a less cushier ride.

I'm currently running 25s but would like to run 28s it I want to use the bike for touring as I could increase the pressures but keep the comfort. The question is would they fit in my frame? Any chance you could measure your new gatorskins for me? (height from rim edge and width). The measurements, 31 mm for 28 mm GP4000II tyres, given in malk's link seems really rather large and I'd like a second opinion.

Thanks.
