Why buy new? I would buy a late model Acord donut from a Junkyard; I mean auto parts recycling center. Take a box of donuts, I bet they would trial fit it for you. Also buy the jack and lug wrench. Lots of these around, as there is little demand for them.
I like junk yards, If you don’t, find the local indpendent Honda repair shop and ask them. The donut has spent its life in the trunk and should be good to go.
I have 2 Acuras with no spares. I live in SW Florida and there is still a lot of roof repair going on, but I have had 2 nails in tires in 10 years. The tire monitoring system warns me before they are flat. My wife could not/would not/and should not change an SUV tire. Acuras include free roadside assistance.
