It sets how far the tire folds under load and how fast it comes back, which decides whether you get a contact patch on a rock or a bounce off it. A good tire on a collapsed insert will lose to a cheaper tire that is properly supported.\u003c\/p\u003e\u003cp\u003eThese are filed by the wheel size they serve, but the thing that has to match is the tire. Where a listing quotes a diameter or a range, check it against the tire you are running, not against the wheel.\u003c\/p\u003e\u003cp\u003eFoam and silicone behave differently and neither is simply better. Silicone holds its shape longer, foam is more forgiving on impact. If you are not sure, the tire maker's own insert is the safe answer.\u003c\/p\u003e","products":[{"product_id":"9879-foam-inserts-3-0-soft-2","title":"9879 FOAM INSERTS 3.0\" SOFT (2)","description":"\u003cp\u003e\u003cspan\u003eFoam inserts, 3.0\" (soft) (2)\u003c\/span\u003e\u003c\/p\u003e","brand":"Traxxas","offers":[{"title":"Default Title","offer_id":45801136062719,"sku":"9879","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/9942\/2089\/files\/9879.jpg?v=1719505907"},{"product_id":"injora-1-9-1-10-crawler-tires-silicone-rubber-inserts-118-122mm-4-75-od","title":"Injora 1.9\" 1\/10 Crawler Tires Silicone Rubber Inserts (118-122mm) (4.75\" OD)","description":"\u003cp\u003eInjora 1.9\" 1\/10 Crawler Tires Silicone Rubber Inserts (118-122mm) (4.75\" OD)\u003c\/p\u003e","brand":"Injora","offers":[{"title":"Default Title","offer_id":48226744074495,"sku":"INJDGT-1906GN","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0273\/9942\/2089\/files\/injdgt-1906gn.jpg?v=1772230717"},{"product_id":"injora-1-9-1-10-crawler-tires-silicone-rubber-inserts-118-122mm-4-75-od-copy","title":"Injora 2.2\" 1\/10 Crawler Tires Silicone Rubber Inserts (146-149mm) (5.75\" OD) (Super Soft) (2)","description":"\u003cp\u003e\u003cspan\u003eThe Injora 2.2\" Silicone Rubber Tire Inserts redefine crawler performance with their durable, waterproof, and temperature-resistant construction that outlasts traditional foam.
