Firestone’s smartphone tyre-pressure calculator app for farmers across Europe has been downloaded more than 43,000 times since its 2011 launch. The brand states that it expects this enthusiasm to grow even faster with the inclusion of pressure data for the new Firestone Maxi Traction 65 tyre, launched at Reifen 2016. The tyre brings longer tyre life and lower operating costs to the popular 65 series for medium-sized tractors.
