anybody have those?? I have a grizz 660 and wondering if they rub or not and how well do they work

 

I don't think that the 27's will rub on your bike. I think you only need a lift with 28's but im not sure. i know a guy who has 27 blackwaters on a grizz 660 with no lift and they dont rub so you should be ok. My 650 kawi has 27's on it without a lift and they never rub.
BTW: Those are a nice tire and rim choice, i reall ylike the looks of the 589's and i hope you like them to.

 

The guy I ride with has 27" Titan 589 MT's on his ITP rims and they don't rub on his 660.
