TRM supplies OTR line to Kal Tire

In the desert of Sonora, close to the biggest copper open-pit mining of Mexico and one of the largest in the world, Italian retreading technology firm TRM has delivered what it says is “the most modern OTR plant” to Kal Tire, a Canadian firm specialising in mining tyres and retreading of the biggest OTR sizes.

The plant was put in operation through the active collaboration of the Mexican field team of Kal Tire and the technical team of TRM.

TRM says it supplied all the required retreading equipment including a dedicated multipurpose working gate with a flexible tooling head to perform the three steps required for buffing and the final grooving; a full automatized building machine with a calender head; a couple of autoclaves and curing presses. The installation allows Kal Tire the full process flexibility for tyre sizes up to 63”.

Kal Tire is Canada’s largest independent tyre dealer and one of North America’s largest commercial tyre dealers. Kal Tire’s Mining Tire Group is an international leader in mining tyre service and supply, servicing more than 150 mine sites across five continents.

TRM – Retreading Technology, based in the province of Trento (Italy), specialises in the design and manufacturing of machines and production lines for the retreading of passenger, truck, OTR and aircraft tyres.
