Load Capacity - Wheel vs. Tire For Trailer Wheel and Tire Setup

Question:

I see that wheels boat trailer specifically have a load capacity and tires have a load range in maximum capacity, but which is more important? If I have a GVWR of 3800, would a wheel with a capacity of 1870 like the Taskmaster / Item # 460545MSPVD, coupled with a tire that is Load Range D such as the Provider ST215/75R14 / Item # TTWTRTM2157514D, which is the most important? Is the wheel being a lower capacity the determining factor, which in this case means that the wheel is not suitable for this situation? Thank you,

With any towing capacity you are limited by the lowest rated component. So if you have a wheel and tire with either of them having a different capacity you are limited by the lowest of the two capacities.

So the tire part # TTWTRTM2157514D has a capacity of 2,200 lbs and the wheel part # AM20364 has a capacity of 2,040 lbs so this would be the overall capacity. The part # LHSJ211G is a similar wheel with a high enough capacity for your 3,800 lb trailer as it has capacity of 1,900 lbs per wheel.
