Why 19?

380/44/R13 and those things hold up to over 4 lateral g's.... I think its mainly due to rotational mass, but since the difference between 18 and 19 is not that

I think its mainly due to rotational mass, but since the difference between 18 and 19 is not that great, cosmetics then come into play, with the 19's filling out the wheel wells more.

Keep in mind that those are sizes that the rulebook regulates, so they aren't always necessarily ideal. Example... NASCAR mandates a 15" wheel, but if you let the teams choose they would probably run a 17-18" wheel to fit bigger brakes.

As with NASCAR/F1... those sidewalls are incredibly stiff.
