Zusammenfassung:	Tire components including bead area components and sidewall supports for a run-flat pneumatic tire that are constructed of a material based upon a cross-linkable rubber composition. The cross-linkable rubber composition includes, per 100 parts by weight of rubber (phr)* between 10 phr-and 90 phr-of a polyisoprene rubber and between 10 phr-and 90 phr of a polybutadiene rubber. The rubber composition further includes between 60 phr and 100 phr of a thermal carbon black having a nitrogen surface area of between 5 m2/g and 15 m2/g and a DBP absorption of between 30 cm3/100 g and 55 cm3/100 g. The rubber composition is cured with a sulfur curing system.
