Thanks everyone for your responses. I was concerned that tirerack might be selling me that size because they seem to be out [in Indiana] of the "suggested" replacement size. I'm not concerned about a *small* negative impact on the handling. However, my wife drive's my 9 month old around in this thing so I want to make sure it doesn't suddenly feel like she's driving a Grand AM
Seriously though, as long as it's safe I'm OK with the different size.
