<p>The wheel with a spare tyre which includes lateral walls of the felloe (11), grooves (12), so outer tyre would precisely fit and adhere to the rims and grooves, thus maintaining the pressure. Larger grooves (13) intended for tyre mounting. Sealed air-cock (14) placed on the wall of the groove (13) closer to the frontal part of the felloe-case. Lateral walls (15) are of the sane height as the lateral walls (11) and, together with the grooves (16) enable the spare tyre to fit and adhere, thus keeping the air inside as it is the case with the outer tyre. The groove (18) is intended for tyre-mounting. On the felloe-wall within this groove there is the sealed air-cock (17), sealed in the same way as the cock (14), and it extends with its length towards the frontal part of the felloe-case.</p> |
