It is my suspicion, based on discussions with the tyre manufacturers that many of you are running with pressures too low.
Avon recommended 28psi for their CR6ZZ's on my Kirkham and they work beautifully at that pressure.
If many of the Cobra guys in the UK are anything to go by, they tend to set their suspension way too firm and then rely on the tyre to provide the compliance.
The numbers quoted earlier in the thread of around 22psi, are far too low.
I previous ran Goodyear Billboards and ran a series of temperature tests at three points across all four tyres and the results showed that once again, 28psi was optimum.
