New Tires ? Different size. P205/55R-16 or P215/55R-16

HI!



I need some help???



My car (05 Limited turbo PT cruiser), takes P205/55R-16 tires. The original tires (Goodyear) are coming a part at 25,000 miles. I want to replace all of them this weekend, with Michelin HydroEdge. But, they (DiscountTire) are out of stock. And they are offering the P215/55R-16 size, claiming that it will actually be a better tire size for my car.



Is this true???



Should I go for this bigger tire???



How it will affect my car???
