Surely they cant be any softer than the 2 flimsy strips of foam that come with the ofna tyres in the first place.
There is different densities on the foam inserts isn't there?
As long as they fit without ballooning the on road tire i could just try to get the hardest one??
Maybe? or do i sell these and go premount
FWIW these are destined for my ERBE-GT build so the weight of the truck is surely a bit higher than the GPT2E that these tires were destined for.
