I believe that a tire size of 255/35R20 has an almost identical overall diameter (within 1%) to the stock 19-inch setup, which should ensure that the speedometer and odometer remain accurate.
I'm curious if using a 275/30R20 tires would work and be a compatible size for a 9-inch wide wheel...
I was curious if anyone had replaced their wheels with the Acura TLX Type-S rims? The specs are similar:

This is the type of nightmare that scares the crap out of me when doing an engine modification! Good luck to you. Sounds like dmd2005 might have your solution. It's great that folks like him share this type of knowledge with all of us. I'm happy to be part of this community!
