700c x 20, 23, 25, 28?

[Andywinds]

I'm currently running 700c x 23 which I have no problem with, again never ridden anything else. How would I check if my wheel can run anything bigger or like MTB is the bead section on the tyre designed to all road rims?

Is my understanding correct that the wider the tyres the more comfort but decreased rolling road? Not that it would make much difference to me!

I think you find out by measuring or trying...of you have a friendly local shop, pop in and ask them.

Or, google the name and model of your bike and 700X28 and see what comes up.

Interested to understand why you're looking at wider?

I'm not really, just interested to know the benefits, apart from comfort. What size do you run?

I'm a definite amateur, so large pinch of salt required!

I have 25 on a road bike, and 30 on my cyclocross bike. I deliberately went wider since I sometimes go out with a mate down gravel tracks, and I was struggling on the road tyres...not sure if the difference is psychological or actual, but I definitely feel safer on the wider tyres off road. On road, not sure I can tell a difference really...though the bikes are so different, it would be difficult to tell

The rims say 622 - 15c.

25 would probably be OK 28 May not. How much clearance is there? Do your rims have numbers on them, possibly 622 - 15?

The rims say 622 - 15c.

Looks like you will be fine right up to 32, depending on clearance of course.

great thank you.

twenny ates are the future...

They seem to say nowadays the bigger the tyre (within reason) = more comfort and less rolling resistance.

I just changed from 23 to 25 and it is truly a revelation in comfort with no loss in performance.

Ok that is interesting.

Ok that is interesting.

Conversely I run both sizes and the difference seems negligible to me. But I would imagine 28s are quite different to 23s.

I'm running 28 on my road bike and am loving it, seems more comfortable and more grip on the corners

I looked for 25s last time I needed new tyres, but there seemed to be a whole lot more decent tyres at bargain prices in 23

Currently running 700c x 38's Due to the mass of recommendations when buying my bike (had them fitted before i rolled out of the store) I'll probably drop down to a 28 or 30 when it comes to change my tyres just to see if it makes me ride any faster.

If you do a lot of cycling on gravel and a little rough terrain on towpaths then 38s would take a few bumps.
