I am running MTR Kevlars and so far they have been nice, also the maxxis bighorns seem to be good value.
Personally i have had a bad experience with coopers, had them in my dads car and the lugs would tear into the tire causing large unrepairable holes, and on my brothers car they would slip on the rims under heavy braking on road, which caused the bead to rip and start leaking, also some scary moments trying to stop
