Delly,
To answer your first question. The reason why i am selling them is because i sent my bike in to my local custom shop last April to have the stock wheels taken off and have chromed and put back on. Well they promised me it would only take about 3 or 4 weeks total which was in time for May bike week in Myrtle Beach. Well as it turned out they weren't able to get them done in time so i had to buy a completely new set of wheels (as you can see in my pictures) to have put on there just in time to have my bike back for bike week. So needless to say sometime in late may of last year they called me to say the rims were shipped back to them. So needless to say i went to pick them up from the shop and they have been sitting my garage in the boxes ever since. The chromer was in Texas and they were called Chome Pros Plating. They look awesome but the new style chrome wheels i got on the bike now look good also. As for the size. It is set up for a 300 rear tire.
Hope that helps
