The BF LP foams are superior they are the flack ones who do not fall apart quick like the white onesTrue, mine are pretty soft. While they are 2 years old, they've hardly seen the light of day in those 2 years. The BF LP foams are pretty crappy too. They went south rather quickly on me. They are intended for plastic 4s rigs though so, I can understand that. Most rtr foams have been a disappointment for me thus far. So wish someone would make MT closed cell or at least quality inserts.. frustrating to see otherwise good tires become unusable.
I had 6 year old ones. Still firm and usable
