The invention relates to a tire with circumferentially zoned tread including peripheral sidewall extensions. At least two pumps run at a mutual phase displacement such that they are able to receive fuel during different periods of time. The self-service portion is accomplished by an assembly of multiple self-service automatic vending machines installed in front of the store. The apparatus has a scanning mode in which the scanning point jumps both from one track to another in a first radial direction and from one track to another in an opposite second direction during reading or writing of a file. An operator interface is provided to configure the system and augmentoverride an executing control algorithm during a procedure. The terminal uses this information to construct a possibly unitary list of the services available on the network.
