Silicone Rubber Insert for 118-122mm 4.75" OD 1.9" Tire, Green

Fit great and perform well, these are very stout as described. Used them on the back tires only for my crawler.

I put these inserts on a brand new set of jconcepts megalithic and to say that I’m blown away is an understatement! The blue ones are perfect stiffness for a 6lb 4oz truck like my enduro. These would definitely need some small foam shims if you wanted to fully eliminate any side to side slop in most tires besides injora tires but they’re so minimal with these tires I didn’t see the need because the side hilling and steering performance were not hindered in any way unless a tire had an absolutely tremendous amount of lateral force on it. They add some extra weight down low which is helpful. They are actually quite softer than what I had seen people say online they allow the tire to conform a lot on a fairly light rig I’ve only been used to proline dual stage foams which are noticeably stiffer than these but I have them on heavier rigs also but these conform in a way that seems to give a lot more traction without losing the side hill and steering performance. Overall I’m enjoying them so far and see a definite benefit over foams you just have to be more mindful of the insert size and tire size so they fit correctly and really you cannot beat these for the price.

Amazing

They work great

Yellows are perfect! I did modify mine in the center surrounding hole with some foam nerf gun pieces to support the sidewalls. Read lots of reviews about them being too soft but they are perfect, actually could go for a hair softer but they may break in and get softer over time

They work well but I think they are too firm this is a heavy truck but I still would go down a level or two to get better grip. They are great quality, I don’t think water will hurt them and they are considerably heavier than foams (not a bad thing).

Perfect for 1/10 rig that weighs about 10lbs. Paired them with ProLine BFG KM3 K8 tires. Right amount of squish and don't look flat.

10lb rig. Just enough squish and flex without looking flat. Really stiffened up my sidewall which helped a lot with sidehilling

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。

Top. Absolut das beste Upgrade

For me these are way better than the foam inserts, better side walling and less tyre folding under load giving more consistent traction.

I love these silicone inserts. They are by far the most cost-effective option in the market and some of the best options as well compared to some of the other names out there I use several of these on all of my rigs with great success.
