Yes, trailer tires are rated by tire. So for example, the Kenda 4.80/4.00-8 Load Range C Tire, part # AM10004, is rated up to 745 pounds at 90 psi. Two tires on one axle are rated up to 1,490 pounds.

You still need to verify the weight capacity of the other components of your trailer. You'll always be limited by the lowest rated piece of the puzzle.

Check the sidewall of the tires on the trailer and you should find a speed rating. For this size 4.80-8 like the part #AM10002 the common speed rating is 65 mph which as long as you kept the speed under that you'd be fine.
