like 15. my favorite a 1951 schwinn spitfire cruiser. also have a 1959 amf roadmaster, 1962 jch deluxe cruiser among others.
yaeh on the it'll be ok answer. once on the rims and tire pumped up, it shouldn't even be noticable. just note that kinked section of the tire and make sure it beads up properly when being inflated. anything comes up, remove and return. but don't think you will need to.
I'd try to unkink it by hand, but if your bike is sitting in your house and you hear the gunshot sound of a tube blowing out, don't be surprised. You run a good chance at blowing tubes out if you use this tire. I'd take panther's advice and send it back.
