Tyres for a smoother ride on bumpy roads

[Mossyboy1978]

Afternoon all

I've recently moved to a road full of pot holes and bumps. It's a bit rough on the S8!

I wondered if swapping out the tyres for something with a bigger sidewall might make a reasonable difference.

I'm currently running 255/35/20s. Is it worth considering an alternative tyre size to smooth the ride out or is 90% down to the stiffness of the suspension and therefore tyre size is going to have minimal impact.

Many thanks
