I actually don’t remember why I started routinely inflating my tires at a few pounds higher than what the bike manufacturer recommends, but I’ve been doing this for decades. I think I assumed that the handling would be more precise with higher pressure, but I am not sure why I thought so. My current main ride, my 2021 Can Am Spyder recommends 18 in front, 28 in back, but compared to any other bike I have had this seems ridiculously low. So I’ve been keeping the front tires at 22 and the rear tire at 32, but now think that the ride is harsher due to my own actions. Maybe I need to go to 20 and 30 instead.
