I've got some of these on the front and have been pleasently surprised. They are a cheap tyre but seem more quiet at motorway speeds than the Falken FK-452s I've had on before (very important to me and my only real criticism of the Falkens when coming from Conti SportContact2s).
Dry grip seems decent enough - more squeal when cornering hard than with the falkens, but they have not understeered away yet. Straight line acceleration seems OK - everything spins up in first, these don't appear worse than anything else I've tried. Solid in second.
I've read the wet grip is not great, but I've not tried that as I don't thrash around in the wet too much.
Anyone else tried them? What do you think?
