Question about tires.

So I'm in need of new tires for my CB 450. I live where there are a lot of unpaved roads, so I'm trying to find something with an aggressive tread such as an ADV or dual sport tire. The sizes of the rims are 100/90-19 front and 130/90-16 rear. I can find tires for both sizes however, not in matching pairs. Does it matter that the front and rear tire are from the same series?
