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.
A tire's rim width range identifies the narrowest to the widest rim widths upon which the tire is designed to be mounted during its tens-of-thousands of miles and years of service.. For example, a tire in the P205/60R15 size is measured on a 6.0 wide wheel and this size tire has an approved rim width range from 5.5 to 7.5 wide. The tire has a section width of 8.23 (209mm) when mounted on a 6.0 wide wheel.
