I've been doing a bit more digging. Apparently, the Goodyear Integrity is available in 175/70-R13. This is the LRR OEM tire used on the Prius. The question is, is it worth going to a wider LRR tire, or skinnier regular tire?

155/80-13 = 6.1" wide

175/70-13 = 6.88" wide

Its a sizable increase in width.
