title: Capture words on the right side of | (OR) in regex expression that are not in the left
body: <p>I am trying to capture words on the right side of this regex expression that are not captured on the left. </p>
  
  <p>In the code below, the left side captures "17 inch" in this string: "this 235/45R17 is a 17 inch tyre"</p>
  
  <pre><code>(?&lt;=([-.0-9]+(\s)(inches|inch)))|???????
  </code></pre>
  
  <p>However, anything I put in the right side, such as a simple +w is interfering with the left side</p>
  
  <p>How can I tell the RegEx to capture any word, unless it is a digit followed by inch - in which case capture both 17 and inch?</p>
