4000 miles on Dunlop 220's
Front is beautiful, back is developing flat center spot
On 98 CBR 600
Projected mileage f/10+k, r/8-9k
For further comparison if you want, I had my stock Bridgestone BT-56's on for 14.5k. Front cupped from braking/cornering, rear flatspotted nearly to bottom of siping, but nowhere near "cords showing".
Yeah, I ride pretty mellow...
