How is Google keyword comparison done?

Question

Search Engine Optimization

Good day. Recently I had to start figuring out how to optimize the site and came across a question that I can’t find an exact answer to yet: if I have the key phrase “restored summer tires R15 205/65” written in the keywords parameter of the page, then this phrase will work, then does it bring me up in a search if a person types in "retreaded tires R15 205/65", "tires R15", "summer tires R15 205/65" or "tires R15 205/65"? Or does it need an exact input match, i.e. a person must enter "retreaded summer tires R15 205/65"?
And are there any tools to determine if there is no spam in the key list?
Thank you in advance.
