The 60/40 axle placement formula is a great starting point and does take into account the tongue of the trailer from where the trailer sits on the hitch ball. Please keep in mind that this is a very basic formula or estimate for axle placement.

For a much more accurate way to determine the correct axle placement for your trailer, take a look at the formula that I have included for you. This formula also takes the length of the trailer tongue into consideration.

Answer 5

Assuming your trailer wouldn't need the capacity of the higher Load Range and you could use the LR C or LR D I'd go with the #AM10235 over the #TR20514 as it has a longer warranty at 5 years when compared to 2 years.

The same wheels can be used for both bias and radial tires. You do not need different wheels for radial tires. The tire you have now that is labeled ST205/75D14 is a bias tire because the D inside the tire size means diagonal or bias ply…
