Looks like I'm gonna have to run a regular street tire since DR's don't seem to be available in the size I need. So I will step down a tire size and go with either a Nitto trip 5 G2 or NT05, or the Michelin Pilot 4S. Those seem to be the tires available in a 295/45/18. I haven't run a regular street tire on this car for a decade or so. Any thoughts? I have the 4S's on one of my cars now and they seem pretty decent but it's only 300 hp.
