I'm looking for tires for a 2012 883L. I can find the front tire size everywhere, but other than the one sold by Harley, I can't find the rear. Sizes are Front: 120/70-18 | Rear: 150/60-17. Does anyone know if a slightly wider or higher tire size would work? I'm not as worried about the price as I am the fact that the original set only lasted less than 4,000 miles and generally get lousy ratings. Any advice as to where else I can find this size rear or if an alternative size will work would be greatly appreciated. Thanks.
