[oil pan 4]

I'm looking for a dreadfully boring LRR tire for my trailer.
There are only four requirements.
1, size. Prefer something 15 inch, but I will consider 14 inch tires also if they are a smaller overall diameter.
2, needs to be at least 175mm wide. If I go to 175 or smaller they may not fit on the rim.
3, would like to get LRR tires.
4, cheap.
5, load rating, as long as it isn't less than 1,200lb per tire I won't worry about it.

The smallest I can find right off are 195/65R15. They are 25 inches tall. That is 2 to 5 inches taller than I would like to be, but I can make it work.
I can't go down to a narrow 14 or a 13 because the wheels have to fit on a 5 on 5 inch brake axle with a 10 inch drum (that's the drums inside diameter) which is really about 11 inches on the out side.
I could switch brake drum hubs to 5 on 4.5 but that would cost an extra $100 to $120 in parts and I would have to buy some 5 on 4.5 inch wheels. This is the worse case scenario so I would like to avoid it.
