Bridgestone/Firestone Europe (BFE) has revealed details of a new, ultra-low aspect tyre for trucks and city buses. Called GMD (Greatec Mega Drive) the tyre replaces a pair of dual-mounted drive axle tyres with a single unit. Advantages claimed by BFE include lighter weight, lower rolling resistance and increased carrying capacity. Sizes are 435/45 R22.5 (for city buses) and 495/45 R22.5 (for trucks). Bus tyres will be commercially available early next year and the larger GMD truck tyres in 2002.
