new tyres advise please

Im going to treat my disco 1 to some new tyres, this is my everyday car but does do a fair bit of gentle off roading due to work and hobbies but realisticly its on tarmac mostly. Im just down the road from paddocks and they do insa turbos for a good price and seem to get good reviews id like to go for dakars mud terrain for looks and capability but dont want to regret it for road driving. So i may go for the all terrain rangers instead.
Anyone got any experiance or help please
