Hi all,

I have a flat spot all the way around on my rear tire. I know that it is a natural wear on tire. I'm planning on racing with this tire. My question is, should I keep it or replace it? The flat spot isn't obvious with naked eyes until you feel it with your hand. The width of the spot probably 1/8 - 1/4". No inner layer comes up, still plenty of rubber left. The tire is GP4000s. Mileage: 1000-1500.




Thanks in advance!
