The SCJ1906H wheel-and-tyre assembly is an aftermarket upgrade intended for 1/10 scale rock crawlers and trail rigs. The machined aluminium six-spoke wheel balances strength and weight, paired with a deep-lug tyre designed to bite into irregular surfaces. It is machined for a 12mm hex and accepts a 5mm shaft hole common to many crawler drivetrains.
Each wheel contains a 100g brass pendulum insert that positions mass low to increase downward force at the tyre contact patch, helping the rig maintain traction on steep lines without adding electronic ballast. This mechanical ballast complements the tyre tread to enhance low-speed crawling traction without changing suspension geometry or gear ratios.
Measured figures for setup and tuning: outer diameter 115mm, inner diameter 48.26mm (1.9"), tyre width 40mm, wheel hex size 12mm, bare wheel weight 172g, brass insert 100g. Apply these values when calculating unsprung mass, selecting gear ratios, or choosing shock valving to preserve crawl characteristics.
Fit notes: built for 1/10 crawlers that run 1.9" tyres with 12mm hex hubs and 5mm shaft hole compatibility. Verify hub and hex standards on your chassis before installation. The set ships with two assembled wheel-and-tyre units, each fitted with the 100g brass weight.
This wheel-and-tyre package is for enthusiasts seeking extra mechanical weight and a more aggressive tread pattern to improve low-speed climb and scale realism without major chassis changes.
