Tire "cupping"

Postby bjcrit » Tue Oct 23, 2012 2:01 pm



I recently bought Dinabeads for front and rear tires of my GL 1100, and all throughout the reviews and advertisments people talked about tire cupping, that they help prevent it. I don't think I have ever experianced that, but would someone be so kind as to tell/explaine to me what it is.
Thanks

Cupping, usually found on the front tire, is where you get scalloped wear on the outer edges of the tire, worn indentations about 2-3 inches in diameter. Common causes are unbalanced tires and underinflated tires. When you lean into a turn on cupped tires, you get a lot of noise as the indentations make contact with the ground.
