Irishfield,,,it happens,,,unfortunately mistakes happen,,i too have forgot to tighten a customers tire,,although it didn't get very far and no problem arose from it,i still made the mistake,,but that is one in maybe ten thousand tires i've removed and installed,,,it matters what happens after that,,and how things were made right by the company,,,we are all human and make mistakes but it's how many and the willingness to make it right when you need to!
