Hello, I am starting to look into possibly getting tracks for the Max IV 2009. I heard the composite tracks are much lighter than the rubber tracks , there for less stress on the wheel bearings and much cheaper to buy. I would need to get 21 inch wheels as mine are 26 inch. The wheel spacers are also needed. The tracks would be just for the snow at my place upstate NY. Any body would like to chime in about tracks??? thanks!!!
