Based on our popular 1:32 Classic Steel Wheels, the 1:24 Classic Steel Wheels are intended primarily for scratch builders. There are two (2) variations of this wheel - one variation is designed for use with 3/32" axles while the second variation is designed for 1/8" axles. Note that both wheel variations are the same size (i.e. take the same tire). Designed for use with Paul Gage H&R Narrow (Rib) urethane tires.
Why Offer Two Axles Sizes?
Many 1:24 scratch builders, particularly those trying their hand at scratch building a 1:24 car for the first time, already have a significant investment in 1:32 parts such as axles, gears and bushings that are designed for 3/32" axles. The 1:24 Classic Steel Wheel for 3/32" axles gives these scratch builders the option to leverage their existing investment in 1:32 parts. On the other hand, the 1:24 Classic Steel Wheel for 1/8" axles lets scratch builders who already have an investment in parts designed for 1/8" axles use those parts.
If you want urethane tires for those wheels, look no further than the Paul Gage H&R Narrow tires made for the 1:24 Classic Steel Wheels.
