As far as the weak sidewalls, I was talking about the *BFG* AT's - should have been more clear. The tires currently on our '99 4Runner are those, and currently have over 100 kmiles on them as well. I've always bought Michelin, BFG (I'll have to report that to the Department of Redundancy Department) and Goodyears, so I know nothing about the Nittos, but others seem to be happy with them.
