Can I trust tyre fitters?

[Nimrod]

I worked at Addison Lee and Delta in London in the early 80's, riding a Z650. I still remember those radios blaring out of a horn on the topbox - dreadful. In those days I rode all week for work, then spent the weekend doing bike related chores and riding to Box Hill or wherever... Life was so simple then ;-)
