change it just like any other tire, you may have to wiggle it to get it to fit over the hub, because it a very tight fit, i had to change mine today.... the other option is to have it towed and get someone else to do it!!
If your talking about the special end on the nut you can either find an old socket that is just a little bit smaller than the one on the tire and pound it on then slowly turn the socket you just put...
well you first start by taking them off 4 nuts then you lay them down take valve core out let air out then lay piece of metal next to rim run car onto metal back off then spin the wheel till it...
