I am placing an order for the C-Series wheels and they talk about using flanged lug nuts. What does this mean and can I use the stock ones or will they loosen up? How many are running these wheels, any complaints?

 

I have them and I use the stock lug nuts. No problems as of yet. I put on about 100 miles so far with them and they seem to be strong and durable. They do scratch just like any wheel, but it is an ATV wheel. They shine really nice and I think for the weight savings, they are a good price. I have heard of aftermarket lug nuts loosening after time, so I did not install them. I also did not get the center caps because I figured they would just fill up with mud. I'm not even sure if they make a center cap for the 650 rims.
