Exactly how do you get your wheels and tires to do this

is it the wheel streched tire like i said i'm unsure and they were telling me if it was double beaded but didnt know what to tell them so may someone enlighten us

o and i'm posting it in this thread because i only see nissan doing this (as you can tell it's rb40mike's silvia)which is why i didnt put it in the sections for wheels and suspension
