My owners handbook says to increase the front tyre pressure (by 2 psi I think?) if rough roads are encountered.
I tried this when I thought I was getting a rough ride on my Norfolk B and C roads.... It's actually pants! What they mean is to increase the pressure to protect the rim from damage in pot holes on proper rough roads such as in Third World countries.
I soon reverted to my trusty 32psi front and 36psi rear.
What you probably need is an all weather tyre. I used Pirelli Diablo Strada and then Pirelli Angel ST, which are both great in the wet and/or cold.
My present pair of Angels are soaring past the 7k mark with flying colours.
If you are more a Michelin Man* then PR3 or 4's might suit you?
* Not a reference to your 92kg...
