How many of you guys have ever noticed how small the rear tire looks on a 1500 classic? I mean,its a 150/80/16 and its the size that comes on the bike,but to me it looks too small and narrow under the fender on the vulcan classic 1500! My other bike is a 03 Honda Shadow Ace Classic 750,just half the size of my 1500 classic and has a bigger rear tire than the 1500 that fills up the space under the fender! I have been looking and studying this thing,and there appears to be about a 1/2 inch or so between the swing arm and the tire on each side. So what other size could i go to bigger, that would'nt rub the swing arm and be a good fit without problems? Thanks,from someone who hates that little bitty rear tire that comes on the 03 1500 Vulcan Classic!!!!!!
