Over the last five years of data collection for the Tyres & Accessories’ ranking of the leading tyre manufacturers, a few trends can be observed – see accompanying graphs for more details. Firstly, it is easy to see that there are a few separate groupings of rival companies within the top ten. In our first chart, we can see that Continental has continued to progress in narrowing the tyre sales gap with Goodyear, partially because Goodyear has yet to regain the level of sales achieved in 2015, despite improved results on its half-decade low in 2017. Tyrepress noted in 2018 that based on tyre volumes, Conti looked likely to overtake Goodyear in light vehicle (passenger car and light truck) tyre volumes, showing how it has gained ground on the previous ‘Big Three’. Regardless of their order, it has been appropriate to talk of a global Big Four tyre manufacturers for a few years.
