The Openfield co-operative that helps harvest, store, and market crops for more than 3,500 farmers across the UK has appointed Michelin solutions to manage its tyres. The three-year, price-per-kilometre Effitires deal replaces a transactional agreement with a competing premium tyre brand, and covers Openfield’s 36 Scania and Volvo trucks, plus a mixed fleet of 46 bulk tipper trailers.
