You guys are brutal man, just because someone doesn't know something doesn't mean they are not deserving of help. I'd rather see someone ask a dumb question than see guys posting BS that they know nothing about (what this forum is mostly full of).
Anyways, zach_24, can you read on the outside of your tire what the tire size is? It could be something like 225/40R18. If you can get that number that would help. A picture of the wheels would help as well or if you have a brand.
Without knowing the size it is hard to say what would fit. You could have too large a tire size for the offset/width of the wheel but without having more info we can't recommend the proper sizing.
