this is true, having tires that are good for off-road terrain does help. but as you know with an SUV like this, it's unlikely that owners will go that far. It's more so the hardcore jeep guys.its more about tires though. you could have all the power and torque you want but if your rubber can't get that power down effectively then its a waste.
At least when it comes to a luxury SUV like this.no doubt tires are important too
but I doubt most people are rolling around in off road tires.
