Tyre Pressures

dg74

Running mine at about 80 psi and I'm a heavy rider. Tyres feel fine, only had one puncture but that was due to the valve splitting from the tube.

No problems, tho I'd say Horses for Courses.

Moving to a Bonty hardcase 25 from a conti GP Attack 22 on the front made my bike a lot less jittery in the wet and didn't discernably slow me down.

Can't say that I have got that accurate on tyre pressure to have a view. If it explodes, I've put too much air in, and if my thumb can touch the rim tape, I haven't got enough in!

"the real difference in rolling resistance........is too small to detect physiologically".

What does that mean? That there is a detectable difference (e.g. in speed as measured by a cycle computer) but you can't feel it when you're pedaling? Or that there isn't a detectable difference?

For my weight I guess I run my tyre pressures moderately high, but I have no comfort problems at all, very few punctures and actually quite like the taught bouncy feeling. When I have lowish pressure in the front tyre I find it a bit disconcerting the way it squidges around when climbing out of the saddle.

If there really is NO detectable speed advantage to running higher pressures I would lower the pressure for better traction though.

@neeb: If you read the rest of the thread you will find that I was quoting an article in the May edition of C+ and they were quoting some research published by the University of Texas. If you need additional information I am sure that they will be happy to help.

I notice that when people enquire about road vibration and discomfort tyre pressures are seldom mentioned as a possible source of remedy.

Thanks; yes I didn't mean to be critical, I'm just curious what they mean by "physiological detection".
