Tires? 120/70/12 What do these numbers mean?

[sscheitel]

I have my trike and it says that the tires are:

FRONT: 120/70/12
REAR: 130/60/13

Can someone translate what those numbers mean and also make a recommendation on which tires I should get?

This would be for street use and I would be looking for the best street tire out there...I hear Kenda is a good tire....but what is the top of the line?

Direct links preferred....but manufacturer & model/part numbers will do as well.

Thanks

First number is how many millimeters wide , the second is the ratio off the sidewall height compared to the width and last is rim diameter . Ty here for tires www.motorcycletire.com/merchant2/merchant.mvc? Pirelli , Avon or Michelin are the better brands
