One question I’m often asked is “which tyre is best for my 4WD?” (usually followed by “how do I get my wife to agree we should spend money on new tyres”).
Before making a recommendation, I always want to know what type of driving you predominantly do? Is most of your driving done on city roads, dropping kids at school and acting as a taxi-service to their many activities, only getting off-road for the occasional weekend camping trip? Or are you planning a touring holiday that involves a decent amount of blacktop and some off-roading. Then your best choice is a good quality all-terrain tyre.
I prefer to use light truck tyres for additional strength and stability when using low tyre pressures. My choice in all terrain tyres is hands down BF Goodrich All Terrain T/A KO2. These seem to handle the additional loads on our cars when touring and camping, as well as giving good grip in all conditions and road types, although I’m constantly telling my wife to slow down in the wet as they have less surface area contact with the road and can slip easier than normal road tyres. They also do very well when run at low pressures.
