Abstract
(EN)
The present invention provides: a sealant rubber composition for inner tire surfaces which is capable of being inhibited from changing in physical property or sealing performance; and a sealant-coated tire obtained using the sealant rubber composition. The present invention relates to a sealant rubber composition for inner tire surfaces which comprises a rubber ingredient, at least one vulcanization accelerator selected from the group consisting of thiazole compounds, thiuram compounds, and dithiocarbamate compounds, and a peroxide, the contents of the vulcanization accelerator and the peroxide being 0.5-10.0 parts by mass and 0.5-10.0 parts by mass, respectively, per 100 parts by mass of the rubber ingredient.
