Another tyre pressure question....sorry
My name is Kris and I'm female on a rigid Haro Mar(t)y 29er singlespeed (32T, 20T).
A couple of months ago I would have said I ride a blue bike with round black wheels. After reading a number of forums and posts, I'm probably at the stage where I have enough information to be dangerous.
Recently I received some advice that I should be deflating my wheels by one psi after every ride until I pinch flat, so I can find the right tyre pressure and provide myself a bit of 'give' whilst riding. Yes, I'm sure this is advice that has been mentioned many a time, in many different posts. I have to admit, I'm slow.
Tonight whilst riding I noticed that yes, the rear tyre pressure was nice and low, giving me plenty of cushioning (I also noticed the rear wheel 'slipped' a few times whilst climbing, but I think this is more my technique than the tyre pressure - yes?). However, I also noticed that whilst the tyre pressure was low, it also allowed the rear wheel to slide out on a number of corners, similar to the feeling when you've gotten a flat.
My question are these:
In the process of reducing tyre pressure to find the right pressure, is there a point where too low a pressure is also bad?
Does body weight or technical ability play a part in working out the right tyre pressure?
And finally, does the terrain play a part? For example, would I have a different pressure for Stromlo over Sparrow over Majura?
Keep in mind when providing your answers, my bike is blue and stick figure diagrams would be most appreciated.
Thanks
Kris
