(4) Sumitomo HTR Z III 245/40R17
 

Just throwing this out there. Very lightly used Sumitomo HTR Z III in a 245/40R17. These were put on the car this last year and only driven to autocross events (Chris switched tires at events), and then he did have a Miata he drove as well. So these haven't seen many street miles.

To get them new from TireRack would run $440 shipped right now. I'd be looking to get $380, and I would even mount them free of charge for you ($99+ depending on the shop with a 40 series).

Any interest?
