A research plan is the main part of a grant application and describes a principal investigator's proposed research. This page describes the essential elements of a research plan. The research plan gives a principal investigator the opportunity to discuss proposed research, stating its importance and how it will be conducted.
Every tire has a load range, and trailer tires are no different. Marked on the sidewall, the load range runs from the lightest weight the tire can carry (Load Range B) to the heaviest (Load Range E). Load range is a measure of an individual tire's maximum capacity to carry a boat and trailer. Most boat trailer tires have a load range of B, C, or D. If a tire has load range C, it can carry 1,820 pounds. If it's on a single-axle trailer, this means both tires can carry a total of 3,640 pounds, which includes the weight of the trailer, the boat, the engine, fuel, and anything else inside the boat.
So even though the OE tire we used for an example is E rated with a maximum pressure of 80 PSI, the plus size D rated tire carries more weight at a lower pressure. In other words, LOAD RANGE E doesn't always mean the tire can carry more weight at maximum pressure when compared to LOAD RANGE D at maximum pressure.
