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.

A larger trailer tire basically wins in every category like you mentioned. Less rolling resistance, less affected by bumps in road for smoother ride quality, and bearings/hub spins less so in theory less wear and tear. So as long as you have room for…

The size 400/480 and 4.00/4.80are the same tire size. The 400/4.00 designation referrers to an older tire size that is no longer available and the 480/4.80 size will replace the older model sized. Therefore, a tire like the Kenda Bias Trailer Tire,…

Typically 4-way wiring consists of 18 and 16 gauge wires. For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector #W787264. The part #HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.
