I run Dunlop kt877 20x10-9 on my 86 200x..... they work GREAT in the mud and they are even better for speed and taking corners fast! they clean off fast and they are lower profile tires so you can get more speed rathen than power....but they work great and I would definately buy another st if I need to!!!!! plus they LOOK awesome! (in my opinion) lol Here are a few pics of them on my 86 200x....
