Our new Anti-Foams are a waterproof tire insert option that will re-define the way we tune our crawlers! Now you are able to run a very soft tire that still handles superbly on side hills. The inserts have a very high tensil strength so they will not tear, and are completely resistant to water as well as hot and cold temperatures. They are the same in below freezing temps as they are in 100degree days. We will also be offering tuning rods, these ruberized rods are waterproof, and they can be used to precisely tune the inserts to your specific needs. DON'T think that you need a stiff tire any longer, these work great being very soft and allow the tire to grab ahold of rocks even better than ever, especially in wet conditions. They offer tapered edges to ease in mounting and increase contact pressures. Please order the exact size for your tire as they are a precise fit. I personally use the soft inserts with a few tuning rods in a 6.5lb class 2. I have also ran without tuning rods and they have worked very well.
These 3-D printed tire inserts are made in the USA, even our material used to create the inserts is made in the US.
