I am a new owner of a 2004 VTX 1300C. Don't know squat about working on bikes, parts, and how they work together. I know how to ride and I have good taste when it comes to what looks good. Not a good combination. My bike has a 170 tire on a 15 inch rim (I think the standard). I want to get as wide of a tire as I can without changing the swingarm with a bigger rim. Maybe an 18 inch rim with a low profile tire. Can I do this without making any other changes to the bike? Is a simple swap?
