INJORA 4-Pack Silicone Rubber Tire Inserts (Yellow) for 1.3 Inch Wheels – 68-72mm Outer Diameter, 24-27mm Width

These INJORA silicone rubber inserts are designed for 1.3 inch tires with an outer diameter of 68mm to 72mm and a width of 24mm to 27mm. Made from flexible silicone rubber, they provide a firmer sidewall support compared to traditional foam inserts, helping tires hold their shape during crawling. The set includes four yellow inserts.

Which tires are compatible with these inserts?

These inserts are engineered to fit the following INJORA tires: 70x27mm Swamp Claw (T1319), 70x26mm Cling On (T1320), 72x24mm XHX Pin (T1321), 70x26mm Crawler Tire (T1311), 70x27mm King Trekker (T1314), and 68x24mm Gripmax (T1350). Due to variations in tire wall thickness across different brands, compatibility with non-INJORA tires is not guaranteed. Always verify fit before purchasing.

Dimensions and material specs

How do these compare to foam inserts?

Silicone rubber offers more lateral stiffness than standard foam, which can reduce tire squirm and keep the tread in better contact with obstacles. The inserts are also waterproof and hold up to temperature changes, meaning they won't degrade as quickly in wet or hot conditions as foam often does.

Frequently asked questions

Will these fit my non-INJORA tires?
Not guaranteed. Tire wall thickness varies by brand, so measure your tire's inner diameter and wall thickness against the insert dimensions. INJORA recommends using them only with the listed compatible tires.

How many inserts come in one package?
Four inserts are included, enough for two axles on most 1/24 or 1/18 scale crawlers.

Are these inserts waterproof?
Yes, silicone rubber is inherently waterproof and temperature resistant, making them suitable for muddy or wet driving conditions.
