While I was on my lunch break today, I remembered that my uni was in the
boot of the car, so I thought I would have a quick half an hour blast
around the Marina. When I pulled the uni out, I gave the tyre a squeeze
and realised that it was quite soft.
Hmm, time to nip over to Sainsbury's and make use of their free air
pump at the petrol station.
I mounted, and whilst leaning on a post, looked down at the tyre. Boy,
that -was- low! I'm not exactly a twinkle toes, and if I'd gone off a
small kerb I may well have punctured the tube with the rim.
Anyway, once at the petrol station, I first checked the tyre pressure.
15 psi.
I run my mountain bike tyres at around 45-50 psi, so I'll play it safe
with the uni and go for 30 psi.
Valve cap back on, and off we go!
Whoah!
What the hell's going on?
I UPD three times in the first twenty yards.
I am -SO- wobbly you wouldn't believe!
It's like I've gone back a month progress wise. I get back to the car
but feel very shaky (physically, not emotionally).
I let some air out and go for another spin. Not so bad this time.
A little more air takes me back to around 20 psi and I'm back in my
comfort zone.
That's better.
Now I understand the concept of the lower the tyre pressure, the more
the tyre is in contact with the floor, and the higher the pressure the
less rubber is in contact with the floor. This is why roadies pump
their tyres up to a gazzillion psi.
So what does everyone feel comfortable with here?
Should I gradually increase my psi and work on my skill level, or is
there any point and I should leave things as they are?
Just wondering.
Blue.
