I was up in London for the Jubilee Pageant, while there I saw a gig trailer with a four wheel set up. The wheels were close together, in about the same place as a normal two wheel trailer. I was towing back to Cornwall with our standard two wheel trailer and was thinking about the benefits of four wheels. A two wheel unit appears to have no margin or safety if either of the tyres blows out or quickly deflates. On a normal road at low speed this might be manageable, but on a motorway the driver would have a significant challenge. Does anyone know more about this? Why do we use two wheel units on our trailers? Are they easily replaceable with four wheel ones? Has anyone had experience of a rapid deflation while towing a gig?
On a happier note, the pageant was brilliant!
