实心轮胎是工业轮胎的一种。其主要制作原料是由一种特殊的橡胶材料做的，除中间很少的空心维持重心以外，全部是实心。它是一种适应于低速、高负载苛刻使用条件下运行车辆的工业轮胎，其安全性、耐久性、经济性等明显优于充气胎，广泛用于各种工业车辆、军事车辆、建筑机械、港口机场的拖挂车辆等领域。

　　国际市场车辆实心轮胎的需求量呈现不断上升的趋势，每年需求增量均接近10%。预计2008年世界实心轮胎需求量将可能达到2500万条。欧洲和东南亚地区是实心轮胎的主要产地。尤其东南亚地区的越南、斯里兰卡等橡胶产量较大的国家，凭借资源的优势，近几年在实心轮胎制造领域发展迅速。

　　我国实心轮胎市场集中度较高，但是行业利润较低。目前全国车辆实心轮胎处于产销两旺的状态，且产量和需求均有同步上升的趋势，这主要是由于近年来工程运输产业的快速发展加大了对实心轮胎的需求。目前国实心轮胎主要产区为山东省及贵州省。整体轮胎市场的繁荣和强大的市场需求带动了山东省和贵州省实心轮胎的快速发展。

　　实心轮胎行业属于劳动密集型和技术密集型传统产业，我国廉价的劳动力在成本上占有很大的优势。目前实心轮胎行业以出口为主，进口仅占极少部分。目前出口量保持持续上升的趋势，出口形势较好，主要出口地为美国、英国、日本及荷兰等地。在实心轮胎出口方面，人民币升值、贸易壁垒、原材料价格上涨、出口退税率下调等因素均给实心轮胎出口企业带来一定的风险，但预期出口依然保持稳定的增长趋势。

　　就我国实心轮胎未来市场而言，新品种的开发以及技术含量的提高是企业竞争的核心点。行业受到橡胶资源紧缺的约束，橡胶价格处于高价位加大了实心轮胎的生产成本，促使实心轮胎的价格不断上升。工程机械市场及工业车辆的快速发展促进了实心轮胎的需求，预期在未来的几年中实心轮胎市场依然会保持产销两旺的局面。

Solid tire, as s a kind of industrial tires is made of a special kind of rubber materials. Solid tire has little hollow to keep the center of gravity, the rest is solid completely. It is an industrial vehicle tire adapted to low-speed and high-load operation under harsh conditions, which has an outstanding advantage over inflatable tires in terms of security, durability and economy. Solid tire is widely applied in all kinds of industrial vehicles, military vehicles, construction vehicles and articulated vehicles in ports and airports.

International market demand for vehicle solid tires is on the upward trend and has an annual growth rate of about 10%. It is expected that the global market demand for vehicle tires will reach 25 million units. In general, Europe and Southeast Asia are the main production regions of solid tires. In particular, Viet Nam and Sri Lanka in Southeast Asia with big output of rubber have made big progress in the production of solid tires.

China's solid tire market is highly concentrated, but its industry profit is low. At present, China's production and sales of vehicle solid tires are booming, and both the output and demand are on the upward trend. This is mainly attributable to the fact that the rapid development of transport engineering industry in the recent years has expanded the demand for solid tires. China's solid tire production is mainly concentrated in Shangdong province and Guizhou province. The overall prosperity of the tire market and the strong market demand has conduced to the rapid development of solid tire industry in the two provinces.

Solid tire industry belongs to the traditional industry with labor-intensive and technology-intensive characteristics. China holds superiority in low labor cost. For the moment, China's solid tire industry is of the feature that exports outstrip imports. China's export volume is on the upward trend and the main destinations include America, UK, Japan and Netherlands. As far as solid tire export is concerned, the factors like the pressure of RMB appreciation,  trade barriers, price hikes in raw materials as well as the reduction of export tax rebates have brought risks to solid tire exporting enterprises. Nevertheless, export is expected to keep a steady growth.

Concerning China's solid tire industry in the future, the development of new products and the improvement of technical content are the core competitiveness of enterprises. The shortage of rubber resources hindering the development of the industry and rubber prices hovering at high level have increased the cost of solid tire, which has pushed up rises in prices of solid tires. Besides, the rapid development of construction machinery market and industrial vehicles has facilitated the demand for solid tires. As forecasted, solid tire market will maintain the prosperity of production and sales in next couple of years.
