While waiting for Pirelli to may be produce 285/50 VR15 for the rear of the Pantera L and GTS, there are the AVON CR6ZZ in 295/50 VR15 which have almost the same diameter as the 265/60/15 (26.61"vs 27.05").
Unfortunately AVON does not manufacture CR6ZZ in 225/50 VR15.
CR6ZZ being road-approved race tires, it seems to me that it is not recommended to use them with front tires such as Pirelli P7 or P Zero which are excellent but "normal" road tires.
But there are the Toyo R888R which are also road-approved race tires that exist in 225/50 ZR15, do you think they are compatible with the AVON CR6ZZ?
