19s look to small for this gem MDX IMO. 22's look a tad big. I'd say 20's have a good look and compromise with ride.
I'd like to see someone run a 20x9.5 or 10 with a 35mm offset and dropped with one finger gap. That's what I will go for, but I still need to take some measurement for figment and decide on a wheel. CVTs look nice tho.
I haven't taken my rims off yet to check but the past rims have been a mix of AsahiTech and Enkei. This is something best checked when a rim is removed and the markings on the inside of the spoke or the hub will show the manufacturer usually. Enkei though is a pretty good bet, since most OEM Japanese manufacturers use them.
