billy, do you [or any others] have much trouble with trailer tires ? especially those that haul the "run of the mill" lowes, home depot, harbor freight, and similar utility trailers ? and if so, how many spare tires/wheel assemblies [along with spindles and bearings if necessary] are required fare ? this may be just a rhetorical or unnecessary question, so please don't hold it against me if it is not a problem. i just wondered.
