If the tires are old and dried out, I would replace them with new.
The trailer will add weight which will work against the brakes. How old are those brake pads? If you are going to pull this trailer in wet or rainy weather Kool Stop brake pads will greatly improve stopping.
If you are in a hilly area, you may find the gearing a bit high for uphill work. The trailer will make that worse, if it is heavy.
