Flipping your question on its head, a lot of cars don’t *need* wheels as big as they are, it’s just what we use because small wheels would look rediculous on a large car.
You can argue traction, unsprung weight, sidewall compliance, bump handling, ride blah blah blah – but 99% of driving is done well within the performance envelope of a small cheap steel rim and unremarkable tire. In fact the aesthetic massive rims we see on lots of modern cars come with plenty of downsides relative to smaller wheels.
