Not that RRBT customer insisted on a white stripe on their tires, it would seem that was Troy's idea, but say a customer did insist on having a stripe on them.
On Nailed for example, I think the standard gold or red stripe tires out there that used to be an option on some musclecars would be too much of a contrast to the rest of the car with the color they painted around the portholes and the emblems.
If that accent was a different color, maybe something other than a white stripe would have worked. I still think they would have went semi-wide white.
I'm looking forward to seeing it in person. 3rd gen new Buick buyer here. Gotta support the team!
