Thanks for all of the input everyone. The Road Machine did indeed come with it's own skewer so I didn't need worry about that as you suggested. My tires are the original from when i bought my bike and are the greatest in the world and I've had a few people suggest I upgrade to something a little less prone to all the pointy plant parts in the desert where i live so I think I'm just going to wear my original tire(s) down and then upgrade instead of spending money on a trainer. Thanks again for your help!
