The consensus seems to be that there are more doors in the world - at least that's what Harry Kane believes - but is there a case to be made for wheels?
Now according to Cars Guide, there are 1.4 billion cars on the road around the world. Now if we presume that most cars have four wheels (sorry three-wheelers) that would give us 5.6 billion wheels but it would also give us 5.6 billion doors as most cars have four doors.
Using Word Reference, we've listed everything that has a wheel in the world that we know of (we dare say we might have missed one or two)
Wheel of Fortune
That list is unlikely to provide any concrete answers to this particular conundrum but it should get you thinking. For instance, just imagine how many computer mouses there are in the world and some of the aforementioned vehicles don't have doors either.
Wales Online recently broke down the numbers just for Britain and found that there were 213.0 million front and back doors in the country but that statistic only covered residential dwellings. For wheels, it was a bit more revealing in that if you counted that most cars carry a spare wheel and if you count the steering wheeling too then the number of wheels is 234.6 million.
Of course, you are teetering on the edge of going down all sorts of rabbit holes here and just looking at Google trends you can already see that people are questioning whether a tyre is a wheel and whether there are wheels in hinges?
Let's just say this debate is gonna go on until the next impossible question comes along.
