Crazy Crawler LaserFoam "Rupture FT Pro" 1.9" Foam Crawler Tire Insert Set (4)
These are the best inserts you can get for the Jconcept Rupture 1.9 tires, albeit with some modifications. These foams are made for heavier rigs (9-11 lbs) and my rigs weigh anywhere 5-6 lbs. So to make these foams work, I cut the spurs on the outer foams (red) and left the spurs intact on the inner foam (white). To compare foam inserts a lot of people use for the Ruptures, Pro-Line Dual Stage. These foams are comparable in terms of softness and squishiness, but the sidewall are much firmer and hold better for sidehilling and those inner and outer tire gripping climbs. Highly recommended but are more expensive than other foams, but the trade off in terms of added performance, it's worth every penny.
