215/60/15 10mm wider, probably not a noticable handling difference in a Camry.
215/65/15 10mm wider, with a slightly taller sidewall which stands to improve ride / decrease handling response, and make your speedo read slightly slow.
I'd stick with the stock size, unless you can find either of the two other sizes cheaper.
we didnt worry about handling or speedometer for the VI - there are no highways, youre lucky to go over 45 MPH, and mileage is a useless metric.
Of course, here in the states, its totally different. I dont see a real issue with the speedometer reading incorrectly - so long as youre aware of it and compensate accordingly. Handling prowess is another issue, though the actual realized difference is probably quite small.
