wanted center line auto drags
 

looking for a pair of auto drags with 5x5 pattern 15x7 i keep seeing 5x5.5 im wondering if there not measuring correctly

It's possible.

5x5 1/2 is Ford 1/2 ton pickup size. Everyone knows Fords wear out before their wheels do.

5x5 is 71 and up Chevrolet/GMC 1/2 pickup size. And Chevy's will wear their wheels out before the truck wears out! Now you know why they're hard to find. 😉

What are you looking to bolt them on?
