My tractor originally came with 15x6.00-6 and 20x10.00-8 tires. Can I
use a different size tire on the original wheel. Say a 15x5.00-6 on
the front for example?

The last digit is the rim size, As long as that number is the same as
in your example they will go right on. The 15X5.00-6 is a skinner tire
but same height.

So the first number is the total diameter of the tire end to end, the
second number is the width and the third number is the rim diameter?
What unit of measure do they use for the width? Thanks for your reply.

No. The first number is the diameter of the rim (20"). The second number
is the width of the rim (10").
The third number is the tire section height (the width of the tire
sidewall between the tire bead and tread).
So, a 20x10.00-8 tire would be 36" high (20" + (2 x 8")) by 10" wide.

That is flat out wrong.

With lawn & garden tires the last number is _always_ the rim diameter. A
20 x 10 - 8 is going to be 20" high, 10" wide on an 8" rim.

There are 2 methods of measuring tires. One of which, commonly used on
small tires - the 1st number is the tire section height and the second
number is the width. 4.10 x 3.50 - 5 is an example of this method. The
other method is when the 1st number is the entire height of the tire
such as the op has. Again the last number is _always_ the rim diameter.
