Insights

Retired and long out of production, Two Tyres, 42 mm Diameter is a vintage Service Packs exclusive whose sealed scarcity has supported long-horizon appreciation, and its utilitarian tire nature keeps demand narrow and condition-sensitive, making it more suitable for specialist vintage parts collectors than broad investors.

Set Facts

The set includes two rubber tires with an outer diameter of 42 mm.
It is part of LEGO's spare parts assortment for Technic and Town sets released in 1985.
The tires are compatible with large LEGO wheel hubs, including those used in Technic, Model Maker, and System vehicle sets from the early to mid-1980s.

About Service Packs

The LEGO Service Packs theme refers to supplementary sets that were released primarily from the late 1970s to the late 1990s. These packs provided additional parts, accessories, or specific components to complement existing LEGO sets. Rather than complete standalone models, Service Packs were intended to enhance or expand upon primary LEGO sets, allowing users to replace missing pieces, add more features to their builds, or customize their creations further.
