i was using a WR set for 25laps and could keep the tyreheat to a decent lvl on that track with FXO.
and i pick´d the fasted lap time in the race aswell..
more likley ur style of driving that toast ur tyres if u have tha probb and imo a End set wouldnt help that mutch..
Taking an hotlap set+setting the front cambers to something around -1.0°/-1.5°+increasing the front pressure slightly should work decently on most FXO combos.
Obviously it's always a matter of driving style in the end, some might have more issues at maintaining the tyres in a good shape than others.
I usually have problems with tyres in FWD cars, try being a little more easy on the throttle out of turns, that way you wont just wheel spin and burn them
