I've heard you can put a 160-80-16 E3 with no probs at all. I know you can put a 150-90-16 dunlop 402 because I had one on my 03.
And the funny thing is, the 150 402 is actually wider than the 160 E3. Both will fit... Anyway, the E3 has like a 900 something load rating!!! Great tire.... Getting very popular.
Thanks guys I have been running a 150/80/16 meztler 880 but want to go as big as I can get away with. Want a Fat Bagger without all the cost to modify rear end.
