I'm thinking of running OTT tracks on my 843 but I would have to get wheel spacers. If I get wheel spacers, the outside to outside dimension of my tires/tracks would be wider than my bucket (bad). I have 12x16.5 tires on it now, what if I were to switch down to a 10x16.5 tire to get the tread spread narrower. Is there any reason I wouldn't be able to do this? Also, do they make rims with an offset (for more tire clearance) so I wouldn't need to use spacers at all?
