Best Comfort tyre suggestions for HDi 19" 235 40

[Griffy]

Having researched alternative profiles, it would seem only by changing to 18" do u even get to 45s - which is too much sacrifice for a potential minimal gain.

So, at least for now, I wish to optimise the tyre Brand / design specifically for pothole tolerance, using OE 235 40 19 rated for the diesel engine weight
