"Big Wheels: A Tale of the Laundry Game (Milkman #2)" is a short story by Stephen King, first published in the 1980 anthology New Terrors, edited by Ramsey Campbell, and collected in King's 1985 collection Skeleton Crew. It was adapted from an unfinished novel called "The Milkman." The events in this story follow the events of the previously unpublished short story, "Morning Deliveries (Milkman #1)", which appears in the same collection.
Its plot centers around two laundry workers named Rocky and Leo in a small Pennsylvanian town. After finishing up a shift at work, the men are driving around, getting drunk, and searching for an auto-inspection station. The inspection certification on Rocky's car runs out at midnight and he needs to find somewhere that will renew it. They are drunk and getting drunker, drinking Iron City beer, which have the likeness of Pittsburgh Steelers players on them. They finally come across an inspection station owned by an old friend of Rocky's, Bob Driscroll. Rocky crashes the car into Bob's garage and in the ensuing verbal confrontation Bob recognizes him. They then reminisce about old times while Bob inspects Rocky's vehicle for certification. Rocky and Leo continue to drink; at one point, Leo falls into a drunken stupor.
After Bob approves the vehicle, Rocky and Leo depart, both very drunk. It is implied that Bob, who is in an unhappy marriage, goes home and kills his wife and burns down their home around 3am.
On the way home on a long, dark, stretch of road, Leo tells Rocky that he sees a vehicle following them, implying that is a milk truck. Rocky's wife had left him for a local milkman, Spike. Rocky's reaction is extreme; he begins speeding dangerously and reveals to Leo that Spike "kills people." It is unclear if there was initially a vehicle, but there is no longer a vehicle when they look in their rear-view. Rocky, however, does not slow down and upon coming around a curve, an oncoming vehicle suddenly appears, riding the median line. Spike and Leo veer and fatally crash.
It is revealed that Spike the local milkman is driving this vehicle and that he is a serial killer, who plans to visit Bob's home later that night, which indicates that he is the actual killer/arsonist and will frame Bob for the deed. It is unclear if Spike has already killed Bob at the garage or will kill Bob at the house.
Although not directly part of the main storyline (which takes on a darkly humorous tone), it's implied that there are links between one of the men and an unsolved murder of a teenage couple, although it is probable that this is another murder committed by Spike.
