Our FS19_4.90 for Ruptures and Trepador comes in three options. Baseline weights are listed, your choice will depend on the rigs weight, how much over or underdrive, your desired conforming rate, and the tire itself can have an impact on support. 🟢 Soft (sub 6lbs) this is our original/standard insert, it is very soft and is reccomended for light weight comp rigs for use in fronts. This does not have our "No Flat" 3rd stage, this keeps things extra soft for those looking for ultimate conformity yet stout side wall properties. Comes standard with our Directional Conforming Rates, and Forward Propulsion Technologys. 🟢 Med (sub 9lbs) this is our mid range insert that comes with our "No Flat" 3rd stage. This provides support for either front or rear and keeps the tire from appearing flat yet still allows for conformity in the 1st and 2nd stages. The no flat stage will indeed conform under heavy load when required to. Also comes with our Directional Conforming Rate, and Forward Propulsion Technology. 🟢 Firm (10 lbs). Made from our standard material, which gives a plush first stage to allow conforming to happen, yet utilizes dual No Flat stages to give plenty of support for heavy rigs and absolutely the best side hill action in the Insert Industry. Most will find the medium insert to be sufficient for support. But if there is any doubt, the Firm is here to ease those concerns! Package contains 2 inserts. (Insertz are printed in our brand colors. They will come in one of 2 colors, random selection, green or purple) We recommend venting your tires when running our Performance Inserts. They are waterproof, temperature and mildew resistant, and designed to support without the need for sealed setups. ***All products are made to order.
