Hello, does anyone know if it is possible to fit a slimmer one (2.50-18)? I bought a Pirelli City Demon 2.75-18 on the fly because it was available in the next shop. Now I have it on the back. The Pirelli feels very safe, but you can already feel the profile and that everything is a bit slower. For the rear it is a good choice. For the front I would like something with less tread, something more agile. Can anyone help me? Thank you!
