[PBO]

Personally, I'd love some belted Truggy tyres

I have a couple of sets of Truggy premounts & they are very durable, foam for on roads are equally impressive if you buy name brand

Expanding foam is the devils work, it absorbs water & the cells break down on impact which means the inside would either turn to firmish mush or liquid mush depending on how they were treated

I have experience with exotic ropes (dyneema, sk75, pbo, kevlar etc) & I was thinking of wrapping the wheel in closed cell foam - like inserts & wrapping that with unlayed rope fibres, then gluing...if it works the way I hope, I'll be happy to share with pics & instructions
