24mm vs 22mm

[Pedro2015]

Is there any actual difference? Or is it all hype? Anyone switched between the two and noticed a difference?

 

[Cyclist33]

Received wisdom/BS has it that 25 mm is better in every way these days...

 

[Mr Celine]

Actual difference = 2mm. Hype? No, definitely 2mm. When I switch anything from 22mm to 24mm I notice a difference of 2mm.

22mm is lighter, which is all important to fat middle aged roadies.

have a look at this other thread about much the same topic......

Think of it more as a 10% increase/decrease in tyre volume (approximately). Then it starts to make sense.

That's a better way of looking at it. The tyre's profile means that the contact patch is the same on a 25mm as on a 23mm but you're floating on a bigger cushion of air.

Ive found the brand of tyre more noticeable than the size .

Not according to Continental it seems.....

 

[Mr Celine]

Why does everyone assume this thread is about tyres? The OP doesn't mention them at all.

There is a useful discussion on the subject here.

At the same pressure. That diagram is crap.

The 25m will give a slightly cushier ride than a 23mm as you can run 25mm at a lower pressure. The same was said some years back when 20mm became 23mm as the desired choice. It's probably down to our roads being crap. I used to TT on 18mm Tubs !!! Tiny !!

Tell Continental about it I only posted What I'd found on the subject......

Yes: a more relevant diagram would have shown the contact areas when both tyres were pumped up to to the middle pressure of their recommend pressure range.

Here you go, this is the link to the full page that I took the diagram from, should have done this in the first place.........
