dunlop sp3000 - damage? - roverman
I have Dunlop SP3000 tyres on my R75. One of the tyres has a slight ridge running down the sidewall (at right angles to the rim). This can be felt by running a finger over it. I've noticed that if you feel the other tyre sidewalls there are other slightly raised areas, effectively like hard spots which you cannot see but can feel. Is this just a characteristic of the tyre or do you think I'm in need of a replacement tyre?.
Comments appreciated.

Cheers.
