I've have the Geo ATR's on the Prado for just over 2 years now. They are 265/65 17. Put them on just before doing the Cape trip in 2011 with the myswag crew, and then through to Central Oz, and quiet a number of trips up to the Vic high country, always towing a big cub camper and they have preformed flawlessly. Have traveled about 60,000k and i reckon they are down to about 30%. Although they are not of the LT construction in this size, I did ruin one on the development road in Cape York with 5000k on it, but that was due to me driving on a flat tyre and shredding it, an a shocking road, and that was after doing the OTL, I haven't had any problems since then, quiet, excellent in the wet and good wearing.
More than happy with mine. Highly recommend.
