"Go a tear" is an expression commonly used to describe something that is done quickly or with great speed. However, there are several synonyms that can be used to describe the same thing. For instance, you could say that someone "raced" or "sprinted" instead of "going a tear." Alternatively, you could say that they "speeded," "zoomed," or "shot" through something. All of these alternatives convey the same sense of urgency and rapid motion that "going a tear" does. By using different synonyms, you can add variety and nuance to your writing and avoid repeating the same expressions over and over again.
