The tire size of 4.80-12 like what comes on the part # AM30630 is right at 3 inches narrower overall than the tire size of 185/80-13 so you would gain over an inch of inner sidewall room like you are needing.

Answer 1

The thing about trailer tires is they are almost all rated for a max speed of 65 miles per hour. There are a few brands out there that do have higher speed ratings, but we do not carry those. I did attach a page to the right that has all of the rim…

Answer 2

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The main differences between the two trailer tire sizes you referenced are the outer diameter for the two and the capacities available. For the 4.80-12 tires they are 20.5 inches in overall diameter and have 785 and 990 lb capacities available. For…

Answer 7

Switching from a 4.80-12 size tire to an ST175/80R13 is quite a decent jump in size but it really just depends on how much room you currently have available both between the top of the tires and fender and between the side of the tire and trailer…

If you find yourself in an emergency situation, you could temporarily use a lower rated tire as a spare until you can get the damaged tire repaired or replaced, but generally speaking you wouldn't want to mix tires with different load ratings…

When you say Kenda Loadstar K353 12", I believe you are referring to the Kenda K353 Bias Trailer Tire - 4.80-12 part #AM10062 or Kenda K353 Bias Trailer Tire - 5.30-12 part #AM10066. Both of these Kenda K353 Bias trailer tires are rated for 65…

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material. For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs. For a 15 inch steel wheel with 1/2 inch wheel studs…
