This forum concerns road bike tyres.
Hello, so recently I’ve put on a rim with an internal width of 19mm and 25mm conti tyres which ended up measuring 30mm wide when fitted and the shape of the tyre is pretty much U-shape with ‘vertical’ sidewalls with no bulging.
How would this compare in terms of cornering grip to a narrower wheel (say 15mm internal) with the same tyre fitted, resulting in a more bulbous tyre cross-section? Which is better in terms of cornering confidence? Clincher tyres
