I'm buying a new trailer and was wondering about the tire size 12" or 8".I was told that a 570x8 tire is 18" diam. and a 12" is 20". That is not much difference. Thoughts on the difference? I guess what I'm asking is DOES SIZE MATTER?? Thanks.

Wheels

The larger the wheel, the less hp to pull it. If you have a choice, go with the bigger one. If you're running 70mph with the bike, you can just imagine the speed of the small tire.
