Tire pressure?

FL-KPM · 04-02-2023, 06:18 PM

So the front tire on my kpm says to inflate to 40psi
Man that seems like a lot of air in that tiny little tire.
What’s everybody opinions on that?

I'm not super familiar with the KPM's, but I would say start at the sticker pressure, and work around from there. As long as the sticker pressure isn't higher than what's on the sidewall of the tire. If the sidewall says the tire can take 51psi, you should be just fine to start with 40psi in the tire and go from there. Just remember that when you're doing your test rides, the tire will get hot and the pressure will change (that's why you always check and adjust tire pressures when cold). If it were my bike, I would start at 40 and go for a ride (and make sure I could replicate the ride for the rest of my testing), then move in 3-5psi increments until I found a pressure that gave good feedback and a smooth ride. You'll have to set aside a pretty good chunk of time to ride, but I guess that's just the price you'll have to pay, right?

Ok thanks I started with 30lbs of air and will see how it handles.

According to the manual, should be 31/32 in front, and 32/33 in back.

Go with the manual, the tire sidewall rating is the maximum.

Always go with the manual. If no manual, it should be on the bike somewhere, like the swing arm. Same as a car, you go with what is shown inside the door.
Tires show the "max" pressure, but a bike or car is designed around a specific pressure that 9 outa 10 times is other than what is on the tire.
