i got a really good deal on a set of rims recently because they had two valve stem holes per rim (factory defect). when i was getting tires put on last weekend:
guy at the shop: yo man you know these have 2 valve stem holes on each rim?!
guy: is there like, a reason for that? like weight or aerodynamics or something? just curious man i ain't seen nothing like this before! it's crazy!
me, losing my patience: brah, you just don't understand! these are racing rims, brah!
i took off before he could further damage my IQ with more of his questions. because clearly two valve stems takes off 30 pounds of weight and streamlines the air flow over the entire car
