245 70 R 16 is a common size tyre and i have run this size on my rovers since 1994. On Performance Wheels 16 X 8.
The last model shape Holden Jackaroo had them and the previous model Nissan pathfinder also had this size from factory plus a few other jap models.
I currently run Pirrelli Scorpion AT, but have also tried Bridgestone AT, Goodyear wrangler , Toyo and Bf Goodrich Trail TA's.
I have found them to be a good compromise for general driving trail,sand and road without affecting performance and fuel.
