4pcs Silicone Rubber Inserts for 1.9" 108-110mm(4.35" OD) Tires,Blue

Be careful with sizing these to your tyres. Somehow I managed to order the incorrect ones. These ones are too big for the 1.9" wheels they were going on. But as all my other tyre/wheel combos have Injura silicone inserts I think I can vouch for the quality of these.

These green inserts are great for fairly light weight rigs. They allow the tyres to conform nicely to rocks etc, add a little weight to the wheels and don’t absorb water so you can use them anywhere. Great price too!

Great product

Took a while to come,but the result was worth the wait,no way could I even get the tyres on with the foam inserts that came with the tyres.

Great inserts. Have these fitted on some Injora heavy brass wheels, brass rings and Injora 122mm by 42mm tyres and the setup is perfect. Keep the side wall stuff while allowing enough softness for the tyres to work.

Designed to fit the Injora Comp pin tyres, you need to do research before buying for other tyre combos. Excellent product, but don't be too quick to start cutting them, they do break in and get softer. Something you can definately play around with. Sidewall support is excellent with plenty of squish. Running on Ecto with Fastrax rims, inserts cut and tyres vented. Out performed G8 Trenchers on Injora Turbine wheels with the copycat AliExpress green silicones. I'd buy again but wouldn't cut them straight away.

These are a must for any crawler. I have fitted them to a number of tyres and they work really well. The tyres in the picture came stock with my crawler and with the included foam inserts were a bit hard. By fitting these they are softer and can now be used for trailing instead of my more expensive ones. Fitting is easy and bead lock wheel assembly seems easier with these inserts as the tyre keeps it shape.

For rc vehicles you plan on getting wet and muddy they are fantastic

Work perfect !

injoraのホイールとタイヤと共に使用しました。 デフォルトのスポンジインナーと比べると縦方向の潰れはイイ感じに変形するが横方向の変形は変にヨレたりせずに耐える感じで、なかなか良いと思う。 浸水してもスポンジよりは乾燥が早いと思うので、それもまた良いです。 1.55のタイヤも購入予定なので、その時もシリカゲルインサートを使用するつもりです。

Fabulous. I inserted them in my Tamiya Lunchbox tires (RC Truck) and they do the job. They are easy to work with as well. I wonder if they could stand to be even a bit heavier and denser. They work as advertised. Durable. Fit exactly as described. Not overly sticky but just enough to make it easy to work with.

Yes happy 😊

Great product! Super easy to install and I won’t go back to dual stage foam any more. I installed this on my VS410 stock tire. Unleashed its full potential instantly. Just bought 2 more. Also it retains tire shape a lot better
