Alright, I got impatient and looked on DiscountTire.com and TireRack.com. First, I see more choices in my current size than I was lead to believe I had from Discount Tire.
About the size, can I fit P225/40 R17 w/o issues? I know I lose just a tad on profile, but not much and I get closer to OEM diameter, and a little more space between my rims and potholes (been a never-ending issue of bent rims) and I think fits my 7" rims better.
Decent reviewed tires by CSVT owners:
P215/40 R17
