Pirelli & C. S.p.A. is aiming to improve its operating earnings margin to 15 percent by 2017 based on increased sales of premium tires, lower debt, improved cash flow and additional efficiencies, according to the firm’s latest five-year strategic plan.

Pirelli said the operating margin should improve two percentage points over the coming four years, with the return on investment improving to 28 percent from 20 percent.

Contributing to the improvement will be an increase in the share of sales from premium products to 60 percent by 2016 from 56 percent in 2013, Pirelli management said.

Pirelli also said it intends to invest $2.3 billion through 2016, although management didn’t specify the nature of the investments. The company did say, though, it expects to achieve about $500 million in efficiencies and cut debt by nearly two-thirds to about $715 million.

Included in the sales projections are goals to consolidate leadership in Latin America and Middle East/ Africa, strengthen its position through-out Asia/Pacific and increase profitability in Europe, including reinforcing the firm’s role in Russia.
