A 4-inch tire is about <strong>101.6 mm wide</strong>, and a huge number of popular U-locks have internal widths under 100 mm. Buy the wrong lock and it literally will not close around your wheel. No amount of hardened steel helps if the shackle can&rsquo;t shut.</p> <p>The fix is to shop by <strong>clearance first, security second</strong>: either a flexible lock that doesn&rsquo;t care about tire width (chains, folding locks) or a rigid lock whose internal width verifiably exceeds your measured tire.</p>
