Tbr7 help finding knobby tires & correct tube

[TBR007]

So after riding my tbr7 on a 12 mile trail ride the other day I’ve come to the conclusion I need a more aggressive set of tires...not that I got stuck anywhere but they are Just more street oriented then I need them to be I’ve found a good rear tire size is 130/80-17 “motoz tractioner” I believe it was called that I’m gonna run from now on it’s still dot street legal but it’s far more aggressive so I don’t have to worry about the Rocky Mountain trails tearing up the street style tires and leaving me with a flat somewhere very inconvenient....I’m having some issues finding a front tire though the stock size is 90/90-19 anyone have any suggestions I can’t come across anything that’s a knobby style....also having a little issue picking tire tubes I believe they’re a tr6 style tube?!? Could be wrong so any help with picking up the correct tubes and a more aggressive front tire would be greatly appreciated
