18" or 19" Summer High Performance Runflat Tires RFT

[Lawfarm]

I picked up a set of Blizzak LM-60 RFTs that I've been running this winter with great results.

My stock Bridgestone all season RFTs are getting down there in wear, and I'm looking to replace the with a dedicated set of summer / high performance tires.

I would like to stick with an RFT. (I know, that's a huge limiter).

They will never be used in snow/cold. Performance on dry/rain is desirable. Also (and I know this is impossible), I have to drive at construction sites, off-road, from time to time, so something that will have some self-cleaning would be nice (but looks to be non-existent).

Right now, it's looking like the Pirelli P-Zero RFTs. Any other suggestions?
