@stuntman No, I would not mix tires like that. I have a set of Model V wheels with Indy 500s that I've been running, and had planned to keep for long distance trips to NSXPO.
I bought a new set of RGIIIs with specs as noted above, for local use, and am trying to choose stickier tires with some wet capability, since it rains here a lot.
Sorry if I was confusing.
Also, thanks for answering my question about wet performance, that is super-helpful.
Just making sure you are referring to to EC Force and not EC Sport (latter have no availability in NSX friendly sizes), before I run out and spend $1200
