New Prius owner for about 3 months but not very comfortable with the factory tires that came with the car: GoodYear p195/65r15. Great mileage but the ride is not smooth, and I was actually considering replacing them with a wider style such as p215/60r15, LRR but don't want to compromise MPG either. Any know issues with changing sizes?? If i'm not mistaken Prius V comes a wider tire as well but I'm not aware how much that affects MPG at all. Any feedback is appreciated. Thanks in advance.
