1:14 Tire Insert 20 mm, model accessory

This 1:14 tire insert in 20 mm format is a dedicated model accessory for Carson references 907012 and 907612. The foam ring sits inside the tyre and provides the internal support that helps the casing hold its shape more evenly while the wheel is in use. Its circular form with a large centre opening is made for placement as an inner support element rather than as an external wheel part. That makes it a useful choice when an existing insert has worn down, when a wheel and tyre set is being rebuilt, or when compatible running gear is being prepared as a spare setup. The stated 20 mm size gives a clear fit reference, while the 1:14 scale keeps the application focused on matching model vehicles. As a replacement component, it serves a precise workshop role in maintenance and setup work. In practice, inserts like this are fitted during tyre assembly to support the tyre from within before the wheel is run again. That makes them relevant for bench work, parts sorting and routine upkeep of compatible 1:14 models, especially where a direct fit for 907012 or 907612 is required.
