I removed my rear tire off my 2011 rt-s, I first removed the trailer hitch no brain-er. then the two 15mm bolts on the brake assy and let it hang. then the Axel(if you use a motorcycle jack like lamonts, position it just a 1/4 inch in front of the catalytic converter,raise the bike until you can just rotate the rear wheel, I'm talking a sheet of paper would just slide between the floor and tire, do not remove the shock bolt, you finish removing the Axel, the tire will drop onto the floor, then jack up the bike, the bike goes up, the wheel stays down, the belt gets loose, jack until you can roll the wheel out the back no lifting, remove the disk assy. then the sprocket, you have to remove the seal on the sprocket, under it is a inside C ring, use tru-ark pliers to remove it, the sprocket will come off with just a pull, now inspect the bearings they should look and feel smooth and easy to turn. if not and you are still in warranty, let your dealer replace the bearings otherwise order the bearings, seals, and o-ring $68.00 for all. any tire store can mount and balance your new tire or you can if you want. then roll your new tire and reassembled wheel under the spyder,put the belt on the sprocket, now!! have a helper slowly lower the the jack until you can slip the axle in, you should use a dead-blow hammer to persuade it, this is not orange county, take it easy. then reassemble everything. jack it up a little so you can rotate the wheel. check for belt tracking and that the brakes work, and your Jim's smooth idler is in position, now go eat supper, you are too tired to clean up the tools, and test ride today. tomorrow you will be ready to do that. :cheers:
felt like posting this again as I am ready for a new back tire
