EDIT: Spoke to Jim and went with the Pirellis, mods can close if they like.

Jim,

I've heard that the PZero M+S is a pretty nice tire for A/S for our car. I've also heard from some locals that the Avon Tech M550 is great as well, and costs less. It also looks like it scored well on the consumer chart. Now the trouble: I can't find it in the appropriate AP2 rim size (215/45, 245/40). What would you suggest I do?

I'm also interested to see if you can get me a better deal than $600 for good A/S tires. That's what I'm looking at for the Pirellis.

Thanks,
Brendan
