Wider tires on base 18's

I personally would not go with the V12's, and I'd honestly go with all seasons over the V12's if I were you, simply because it simplifies things. The soft sidewall of the V12's combined with the sidewall profile you are dealing with on a set of 18's is really going to be a pretty uninspiring ride.

Both Pole Position options are pretty solid. They're a good tire with good grip, and they hold up well even on the 18's.

I would probably skip the RE11's for your use, you just won't see enough life out of them, and if you aren't driving hard, they are not worth the extra cost.

The Advan sports are a pretty decent tire, but you've already run them and you know how they are.

One other options you may want to look at (though I'm not sure they have them in your size) is the Star Specs. They are one of my favorite tires for tall sidewall use, and they are a pretty inexpensive tire that offers some great performance. They were my absolute favorite tire I ever ran on my s2k.
