Rate set to increase to 25% on 1 January 2019 The Trump administration upped the ante once again in the ongoing trade war between the USA and China on 18 September with the introduction of tariffs on all US$200 billion of imports including basically all categories of tyres, retreads and inner tubes. At President Trump’s direction the additional tariffs will initially be set at 10 per cent and will take effect on 24 September 2018. However, as of 1 January 2019, the level of additional tariffs will increase to 25 per cent. Affected tyre lines include new: car, bus and...

Goodyear is the ultimate authority when it comes to heavy OTR tyres. The casing of these OTR tyres have no equal and the high quality rubber prevents flat tyres. Goodyear OTR tyres are made of durable compounds, which make them extremely suitable for heavy loads. They also provide excellent traction. Example of a Goodyear OTR typeGoodyear Dozer and Loader OTR tyres for use in "Dig and Load" will not build up when operating. With the advent of new earthmover operational techniques, loaders are increasingly being used as transport vehicles. When a loader is used to haul material distances greater than...

Deflection is a result of poor tyre maintenance. Most of us are guilty of not thinking about our tyres until it blows and leaves us stranded on the side of the road. Deflection is a term that confuses people and most think that it describes the bulge that forms at the bottom of a loaded OTR tyre. That bulge is instead the result of deflection. To put it in simple terms, deflection is the change in a tyres radius that happens when a load is applied to the tyre. To find out what the deflection is in a tyre you...

BASIC COMPONENTS The construction of Off-the-Road tires depends, to a large extent, on the intended use of the tire. However, there are common components, to all Off-the-Road tires, including the tread, carcass, beads, breakers and sidewalls. Tubeless-type tires have an inner liner. TREAD The tread is the outermost covering of the tire, and is the only part that normally comes in contact with the road surface. It, therefore, must be designed to protect the body of the tire from cuts and wear. Depending on the intended use of the tire, the rubber compound applied to the tread will be changed...

What is the difference between radial tyres and diagonal tyres? 'Radial tyres' and 'diagonal tyres' are 2 terms that also apply to earth-moving tyres. The two tyre types are distinguished via their respective structures. Radial tyres Radial tyres were developed in 1946. There was a need for more flexible tyres, which were able to absorb shocks generated by road surfaces. These tyres are also stronger, which means machines can be operated at higher capacities. In radial tyres, steel cord plies are placed on the heel of the tyre, and a belt is placed across the casing. Because cord plies are...
