Whether you call them off-the-road, OTR or earthmover tyres, these products are some of the most valuable tyres in the market. And with good reason. Not only are they the physically largest tyre product segment on the planet, these products are often also required to endure the greatest pressures in the most unforgiving circumstances. However, due to the relative small unit volumes involved combined with the high individual values of each product, prices in this segment - perhaps more than any other - feel the international ripple effects of legislation, supply and demand around the world.

So, when there's a production problem in one country, there can be a supply problem around the world. And when there's a tariff in one country, product will need to be sold in other markets or at higher prices in the tariff-affected area. With the US Department of Commerce considering a new round of tariffs against OTR tyres produced in China, in the May issue of Tyres & Accessories, we consider all the big news from this large sector.
