Not to good with my tire sizes[:'(]. I have stock 150/80/16's on my nightster but I wana run a 160 cause its the widest tire I can possibly run. Now I have looked at a few different tires but what should I look out for??? Is 160/80/16 okay to run? I understand the width is bigger by 10mm and the other numbers are the same but won't the tire be taller? My understanding is that the second number (80) is a percentage of the width[sm=confused06.gif] I am probably wrong but thats why I am asking.
