In this paper, the design concepts necessary and problems encountered in the development of sidewall reinforced run flat tyres are studied. Despite the disadvantages in aspects of ride comfort due to the thick sidewall, sidewall reinforced run flat tyres, compared to other types of run flat tyres, have more advantage in use of commercially available rims, easy assembly of tyre and rim and manufacturing processibility. Kumho's main aims in development of sidewall reinforced run flat tyres are to understand run flat tyres, to get ideas for new concept run flat tyres and to prepare for the run flat tyre world market of the 21st century. If it is not otherwise mentioned, Run Flat Tyre in this paper means a sidewall reinforced run flat tyre. A finite element method is widely used to understand the basic mechanism and to design the construction of the run flat tyres. (A) For the covering abstract see IRRD E102864.
