But for country lanes I find 25mm fine, faster than 32mm, and I don't remember having too much trouble with 23mm. And when you get down to it, the difference between 23mm and 28mm is only 5mm, which most people would regard as no big deal.
Do the maths on air chamber volume
But does it make that much difference? I don't think it does. 28mm tyres feel only slightly different to 25mm. It's Princess and the Pea stuff. I don't feel all that much more comfy on 35mm Hypers compared to 25mm GP 4 seasons, both being good at taking the sting out of the road. For me the big benefit of the larger tyre is that it removes most of the risk of wrecking a rim on a pothole.
We'll have to agree to differ,though I haven't ridden 25mm GP 4 seasons,I've ridden other 25mm tyres and the difference between them and 35mm is huge for comfort,especially on rougher tarmac the UK is renowned for,though the bigger tyre is slower IME it ain't enough for me to worry about,but one area I really appreciate is descending,where 35mm Hypers are far,far faster and more secure especially on rough/bad tarmac.
