These are better tires then OEM. I used one of these tires in the rear of my navi to fill in the empty space before i had a rear fender installed and it looked amazing. Just having the single tire made a huge difference IMO while also making the navis rear look even better. 

The tire sizes you want to get for oem rims are: 

Back tire size - 130/70R10 

Front tire size - 110/70-12
