Tyre pressures vs suspension settings.
I've been trying to change the suspension settings to get it to ride
well and corner properly on my local roads. It's better but I'm still not happy. My other bike is much better. It
strikes me that there's no point in tweaking the damping if the tyres
are flexing excessively.
My point is that the bike manufacturer's original recommendations and
the tyre manufacturer's current spec no longer match when we fit a
modern tyre to an older bike. Mine has stock suspension and settings
designed to work with the tyres available in 2003, at 36psi front/36psi
rear. If more modern tyre construction relies on a rear pressure of
42psi to get the same profile and sidewall stiffness then running them
at 36psi is like having a flat tyre. And that's the feeling I'm getting.
I suspect that lowered pressures are not intended to achieve a larger
contact patch, contrary to what you often hear. The track riders only do
that because they anticipate increased tyre temperatures compared to
road riding. Once they're fully warmed up they're back to the same
pressure as a road rider, meaning that the profile, contact patch and
sidewall stiffness is correct.
Ths is all just speculation, you understand! I'm going to put the rear up to 40psi and see how that feels. Then maybe tweak the suspension back the other way again.
