Tire pressure

Why do the flatlanders prefer such small widths? For me the bigger the tire the easier it is to carve around on one wheel.

Back in the 2.1/1.95 days, I used to prefer a softer tyre than most, around 50psi. Mostly to give the joints a bit of a break. I used to get a lot of flats.

Now I'm on 2.4/2.15, I actually run them harder, about 80. I found that big tyres flex too much otherwise. Also, I think a big tyre has more give than a narrow tyre at any given pressure - so I can now run harder pressures than before and my knees are still happy. Consequently, as well as more grip, I also have more speed on bigger tyres - not what I was expecting! I resisted big tyres for ages, but now I'm so converted that I'm really thinking about 2.4/2.4, even more speed...

Also something else I only just appreciated recently is the effect these huge new tyres have on bb height and head angle. 2.4/2.15 Rubens slacken your bike by nearly a degree, and raise the bb height by 0.4" compared to 2.1/1.95. And the wheel diameter is more like 21", getting closer to a 22" cruiser.

much less flex in the tires which fucks with your balance, as it introduces a delay in your pumps. plus the extra friction eats away momentum, and it's really noticable in flatland

used to be a strict 90psi guy ( 2.25 dirt monster/ 1.95comet)    but I'm old and my wrists hate the psi...  so i run 80/85psi (2.4 ruben/2.2 t1)   The t1 tire is slow as fuck at 80psi or less.   My wrists hate me so much anytime i land flat on a 1/4 or jump.   One of my riding buddies runs like 45-50 psi front and back... he also can't get more than a ft out of a 1/4 or hip and doesn't jump anything...  Ill never understand low psi for anything but street.

I run about 40. I used to run 90 or 100. Then I only had a hand pump for a few years and got used to low pressures. Anything higher than 60 feels gross to me. I don't really ride ramps.
