Sumitomo Tire Rims: The Next Big Thing

A new kind of tire that’s fast, responsive and lightweight, has been developed by Sumitomco.

Called the Sumitome, the tire uses a novel approach to tyre construction that it claims reduces the weight and costs of making a tyre by a factor of 50.

The Sumitomer, which is currently being tested in Australia, uses an alloy material called polyamide, which was originally developed for tyres in China.

It is now widely used in tyre production and is cheaper than conventional aluminium or steel.

This is thanks to its high density, high-strength properties and its ability to stretch and deform over time, as well as being able to absorb water and gas.

The team behind the tyre, which they hope to launch in 2019, say they have achieved the best combination of properties to provide high durability and flexibility.

They also hope to develop a new kind.

The tyre’s construction is based on the principle of elasticity.

In a nutshell, elasticity is the force between two forces.

In the case of tyre, this is a force due to the rubber that contracts over time.

The pressure exerted by a tyre on the road is a function of both the initial and the final pressure.

So the more pressure you put on the tyre in the first place, the more elasticity will be present.

The result is a tyre that is more resistant to rolling and rollover and more responsive to the forces on it.

“We’ve found that if you use the same amount of rubber as a tyre and you compress it, the amount of elasticities will also increase,” says Sumitoma senior engineer Toshihiro Yamaguchi.

The idea behind this is that the tyre will shrink as it absorbs and expands.

If the compression rate is very slow, the tyre may absorb some of the initial pressure and shrink, and if the compression is very fast, the pressure will compress it and make it stiff.

So a tyre’s shape, stiffness and flexibility will all be increased.

The tyres themselves have a diameter of less than 0.5mm and weigh around 0.3kg.

The material that is used in the Sumithomas is made from polyamide.

“It’s very strong, but it’s also very flexible,” explains Yamaguch.

“When we compress the tyre on a bicycle or a motorcycle, it absorbs about one-quarter of the force.

But when we compress it on a car, it loses about one third of the forces.

This gives us an idea of how much force it can absorb.”

The Sumithome tyres are built using a special method known as high-friction plating.

In normal tyre manufacturing, this process uses very thin, rigid rubber to form a mould and then to fill in gaps between the rubber sheets.

However, with the Sumitsome tyre, the material is made of a different kind of rubber called polyethylene (PE), which is very elastic.

As a result, it will expand very quickly.

“This elasticity enables us to build the tyre to a very high pressure and the tyre itself to shrink very quickly,” explains Sumitomi’s Yamagukuchi.

“In addition, because we’re using this material, the overall pressure is reduced by a ratio of one-half, which means we can produce tyres that are lighter than normal.

The engineers also want to improve the tyre’s flexibility. “

The combination of these two properties, high durability, high flexibility, and low weight, makes for an ideal tyre,” adds Yamagurich.

The engineers also want to improve the tyre’s flexibility.

For instance, the Sumiomos tyres are capable of absorbing up to one-fifth of the energy from road vibrations, which might not sound that big but it can significantly reduce the tyre lifespan.

“Because the tyre is so flexible, we’re able to compress the tyres very fast,” says Yamaguhara.

“But because the tyre has so little rubber, when the pressure on it decreases, it expands, so the tyre can be very strong and the tyres lifespan is also extended.”
