Why do car manufacturers use unsymmetrical 7 spoke alloys?

Question

7 and its multiples do not divide into 360 degrees. As the rest of car design meets the requirement to be as symmetrical as possible it seems strange that seven spoke wheels were even tried.

Answer 1

It's just a design element.
The badges on many cars are not symmetrical either.
Nor is the interior, or the under-bonnet package.

Wheels generally have symmetry, but rotational symmetry rather than reflective symmetry - the mid-90s Ronal "Teddy" is the only wheel I can think of without rotational symmetry (although it did have reflective symmetry in one plane).

Some cars didn't even have symmetrical wheel layouts - the rear suspension system used on the Renault 4, 6, 16 and first-generation 5 meant that one rear wheel was 50mm further back than the other.

Answer 2

for me 7 spoke is as unsymmetrical as 5 are. don't see any reason other than 7 spoke being more stronger than 5 and may be popular now a days.

Answer 3

cos theyre more expensive than 5 spoke

Answer 4

I think they look great on the right car.

Answer 5

Odd numbers look better
