I purchased these tires for my 2010 Prius. I had the Goodyear assurance prior. I only got 22,000 on the Goodyears. I only have 1,000 miles on the Conti's, but they are quieter, handle better, and seem to be an all around great fit. Obviously the Prius is no star performer, but it does perform at the pump. The Goodyear LRR tires should got me about 47.5 MPG. I hope these do better. I will update at 5,000 miles.
