My dealer is going to change the suspension and tyres on my 02 SC 430 from runflats to normal tyres.

I am told they will fit Pirelli P Zero's

Does anyone have experience of these or any suggestions as to the best replacement

Thanks
Mel

Have had Pirellis on my LS400 which seem good for grip in the dry, not so good in the wet.
You can look up tyres, together with German Authority Tyre Tests at: http://www.mytyres.net

Might also save you some money compared to the dealer price.
