245/40-18 Tyres help

[Animal]

I have a BF XR6 magnet ute with Dunlop SP sport 9000 245/40ZR18 tyres, I have never been a fan of Dunlop tyres and are keen to remove them from the vehicle and replace with a tyre with better grip.
I am asking if you have a better brand of tyre (18") with lot's of grip, at least more than the Dunlops, don't care much about wear rates.
I have done 5,000 km and the tyres are hardly touched as far as wear is concerned but would prefer a tyre with heaps of grip rather than heaps of km before replacement.

Cheers
Peter
