Code 110 wheels are .110in wide and Code 88 are .088in wide. Code 110 wheels are the common (or Standard) width wheels and Code 88 are what is called Semi-Scale and are used when the modeler wants a more prototypical looking wheel width. Actual HO-Scale prototypical wheel width would be around .067in wide and although they will run OK on the average track they will not go through common turnouts and crossings. Code 88 (.088in) is just about the minimum width of wheel that will run on most standard or common track if gauged correctly. It really is a matter of appearances because there is very little operational differences between running Code 110 or Code 88 wheels. Code 88 wheels look really good and are most noticeable on open frame cars like hoppers and tank cars. However, they also look great on boxcars, gondolas, and reefers but not quite as noticeable. As mentioned above track code and wheel code have no relationship meaning Code 110 and Code 88 will run on most any code of track. Track code is simply the measured height of the rail, code 100 is .100in tall, code 83 is .083in tall, code 70 is .070in tall, and so on.
