Ok, I need some information. Saturday, when I came off the river I had a boat trailer flat. That in itself is no issue. I changed the flat. Here is the issue, when changing the flat tire, I noticed I two different size lug nuts. Once they were removed, I seen why, the holes in the wheel were worn out. Yesterday, I ordered new wheels and tires. Now the information I need. My boat trailer is a four hole 12" wheel and tire. I need new lug nuts. What size do I need to buy?
