Need a spare tire asap

[htoniv]

Hello, i currently have a 2LT RS package 2011 camaro,

I am going on a small trip and i would be needing a spare since i dont want to risk blowing my tire and having no options again..

The Kit from GM is 350!! :(

i am looking for another option,

does anyone have a spare that fits that they are selling in long island
new york?

If not i am looking to buy another smaller tire that fits in the back spare tire space and fits on the car and i need information and help with that,

This is kind of an emergency since i will be leaving in a few days so any help is much appreciated

Thank You
