Now I was willing to accept this if you wanted something special. Mud tyres or spikes or combination road / gravel tyres or even doing 45° angle corner leans at 80kph down Alpe d’Huez or whatever but surely, SURELY, for just going A to B in an paved enviroment it wouldn’t matter?
Yeah no turns out the premium shit does feel great and rolls better. I can never return.
It’s an old standard, quite a bit larger than 27.5" ironically. Slightly larger than 700c even. I have an old bike that uses them, fortunately continental still makes gatorskins that fit them.
