White letter tires...done

Very cool. What kind of paint did you use?

Sharpie fine point paint pens.

Looks good. Too good in fact. Go flop that thing around in the dirt already!

Any idea how well it holds up?

Haha I just got it recently. I've been out a few times with it and it's insane on 6s. I gotta find a place to jump it around here. But it's a blast for sure. And I always clean up after runs

I used the same method with a white sharpie paint pen as for longevity I have two runs on the tires first run was okay second run paint is cracking a little bit but still on lettering. I can tell it will come off but it looks awesome your first couple runs. I think for street tires it would last longer...as they are not going to take the abuse from off-roading, flipping, and bashing.
