Silicone Rubber Insert for 118-122mm 4.75" OD 1.9" Wheel Tires(Large Blue)

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

Fit the super swamper perfectly, my trx4 is about 10-12 pounds and the blue inserts handle the weight of the rig nicely. There performance is unmatched and will never buy foams again😂

Great inserts would buy again

They are the only one I put in my crawlers . Completely changed its abilities. Fits perfectly in a 4.75 tire

Recommended inserts for crawlers. These add a little weight & make for some good grip

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).

Grate inserts and for the price you can't beat that the blues are a medium softness great side hill action and if you get them wet is alright cause the silicone dont have to worry about any foams any more

works perfectly in my proline hyrax predator. i have a 11 lbs crawler, and works amazing.

Good quality my stock trx4 tires foams got degraded and these were the best upgrade.Satisfied

Azules son más duras de lo esperado. Les corte 1 perfil si y 1 no en el aro más exterior, las suavizo y mejoró bastante la tracción. El detalle es q son diseñadas para los bastante estrechos neumáticos Injora. Para los neumáticos más anchos como los Canyon trail son bastante delgadas..tuve q cortar unos aros de 2mm de espuma tradicional , colocarlas del lado exterior y mejoraron mucho más. La dureza q ofrecen para las laterales es perfecto..no se deforman como las espumas tradicionales... con estas 2 mejoras q les hize mis Neumáticos Canyon Trail ahora van mejor aún.

Update i also got some red inserts and my Updated recommendation is green for total rig (battery inc) weight less then 3.4kg blue for stiffer tyre (22psi) at 2.8-3.8kg blue for squishy tyre at 3.8-4.8kg (11psi) red stiffer (22psi) 4.2-5.2kg if its 5.2kg+ just use red Now mind you i have had the blue for a few months so its worn in and i only took the trx4 out once with the red inserts. the inserts were tared off before applying weight for the photos Good weight to it compared to the foams so just note that extra weight if your looking for advice on what colour u wanna pick i bought blue and it seems to be the go if your car weighs from 3.5-4.5kg so go green if ur car weighs less or red if it weighs more at 4.4kg my car fully squished the tyre once all the cars weight was on the one back tyre also very stiff side walling. for such a low price and the confidence knowing no matter the conditions the tyre will react the same is definitely a must pick over foam however i wish it came in different sizes thses are kinda just made for injora tyres

Buen material

These are pretty heavy...
