New tyres fitted to two caravans,a BMW 3 series and an Audi A2

We visited a caravan storage site and fitted four new tyres to two seperate caravans as both sets of existing tyres were cracking on the sidewalls. We then visited a customer in Cambridge and fitted four new runflat tyres to a BMW 3 series.The customer asked us to supply and fit Continental Sport Contact 3 size 225/45/R17. We then fitted four new tyres to an Audi A2 in Newmarket and the customer requested we fit Pirelli P7 tyres size 205/55/R16
