Road Wheels & Road Wheel Recommendations?

I've been running a rear wheel with A23 rim for last 3-4 weeks with Vittoria Open Pave 24c tyres and you really can reduce the tyre pressure drastically.

On 23c and at 65kg you apparently can go as low as 65-70 PSI and inflating your tyres to anything like 'normal' pressure risks compressing rim so much you can lose spoke tension.

On normal rim at 100 PSI 24c tyre measured 24.2mm wall to wall, on A23 at 80 PSI (I'm over 90kg) over 26mm. Really really comfortable and noticeable improvement over my open pro wheel

Sorry - can you explain this in an idiot dialect so I can understand?

I've always just shoved on 23mm tyres and inflated them as high as their rating allows (150psi for the panaracer at the front, 120psi for the tame gaterskin at the back). I'm 95kg. Am I risking some sort of Singular Event? Or is there something in your findings that'll make me go even faster?
