I have Dunlop sp9000 275x30x19 got about 10k miles from them was dismounted and rotated, wear is even..These tire are rated with 280 treadwear. looking for something that will last a little longer. the dunlop Direzza have treadwear of 300 and falken st-115 have 360...would like to keep with same tire manuafacture as my front if possible..funny thing is that even with tire feathering concerns the front tires still have about 60% treadlife left.$500.00 every 7 months is so unkool ..sorry to vent
