大径ホール+サイドの薄いタイヤを想定した技術。
ホイールのリムを2重にし、タイヤ側のリム（フランジ）をゴムで作成。
自転車で言う「リム打ち」によるパンクを防止する。
この技術は、自転車にも有効に見える。
よくよく考えると、タイヤ屋がゴムでリムを作るなら、タイヤと一体式でも良いのではないかと感じる、今日この頃であった（笑）
How It's Made Wheels and Tires. MAXION Flexible Wheel with MICHELIN ACORUS Technology Reinventing the wheel – Bends but does not break
Factory Design. Innovation has always been part of Michelin’s genetic code – driving mobility and tyre developments for more than 100 years. Now with MICHELIN ACORUS Technology, in partnership with Maxion Wheels, Michelin is reinventing the wheel to help eliminate road-based damage to tyres and rims.
Michelin How to make flexible a wheels. The patented new technology, developed by Michelin and Maxion Wheels for the passenger car wheel market, incorporates two flexible rubber flanges mounted on a special wheel body to create a flexible wheel that improves the ride and comfort and also absorbs impacts from potholes and kerbs. The new wheel is compatible with all tyres on the market and comprises an alloy rim – which is narrower than normal, two rubber flanges and an optional cosmetic insert to protect the alloy wheel.
In tests with a 285/30R21 tyre driven through a pothole*, the standard rim version punctured the tyre at 28kph whereas the Flexible Wheel with the MICHELIN ACORUS Technology did not puncture, or sustain damage at any speed.
