The NSX could fit four, but they were smaller. Just had them in tire bags and I could put 3 in the passenger side - one behind seat, two in seat. Tight fit. Trunk had cutout to hold one when you had to use spare (stored in front, compact).
So taking out spare should hold one, passenger seat one or maybe two (their kinda wide) and I bet another would fit in the trunk. I'll try next spring and see
