Good to know. BTW, for all searching tire options, this is a great site:
https://tiresize.com/comparison/
As it shows (seamingly) all available tires and where to buy them. TireRack is good, but only shows that brands (and sizes?) that they carry.
The 225/45's are about .3" larger in diameter that the 245/40's. Of course, as George and others have pointed out, width can also be a factor.
