What is the best 'tire black' for detailing?

[WE B CRUZN]

This is one of those to each their own kind of threads. If you like em shinny use this, if you like em dull or flat use that I myself like them kinda in the middle and don't like to have to apply the stuff every time I wash the truck to make them look good. So when they need to be done I use spray nine and a good brush to clean them then I use formula 303 on them and it will leave them with a matt finish, not flat but not shinny either and it will last for a few wash's before needing to be redone. This stuff also works great on the inside of your truck as well ive been using it for 13 years now.
