I also have a 2014 Prius, the 3 model. I purchased a new set of tires for my vehicle not long ago, size 195/65R15, and was looking for a nice all-season tire that will give me a good life. I settled on the Nokian Entyre 2.0. Having run Nokian winter tires in the past (phenomenal!) I decided to give their all-season option a shot. It has an 80,000 mile treadwear warranty on it and is also a low rolling resistance tire, so it gives me the two things I was looking for most specifically. The price point isn't bad either. I purchased from TiresByWeb.com for $113, and shipping was free. Had a few technical questions regarding the tires and they were very knowledgable.
