Hi all. The time is looming when I need to change all four tires on my 4.2 S/C. Currently it has the factory Pirelli Scorpion Zero 255 50 R20 109Y fitted. During my search the Avon ZX7 tyre is being offered, it has an A rating for wet grip rather than B for the Pirelli. With the fuel and noise the same. I do occasionally drive off road on wet grass and mud/ruts. Has anyone experience of this make/ type of tire? Thank you.

I have also looked t those Avon ones, but am considering changing to the Avon's but at 275 45 20 instead.

Alistair, thank you for your reply and post link. I had read this prior to posting my question. I have arranged to visit my local(ish) Avon dealer to have a look at the tread to see how they compare with the Pirelli Scorpion Zero.
