A.J. I know you have owned a Countach before so maybe you can help with this question. I am interested in a Anniversary model and note that the rear tire spec is 345/35 VR15. It appears that Pirelli does not make that tire in that size anymore. They still make the front tire. To stay with the same tread pattern, Asimmetrico unidirectional, any suggestions as to what could safely be used to substitute for the rear 345's? This seems to be an emerging problem with Pirelli. They have also discontinued the rear 335/35 ZR18 P Zero's for the Diablo creating real problems for the owners with the VT models as they cannot mix sizes beyond the 1 percent max allowd by Lamborghini without risking damage to the Viscous Coupling. Thanks.
