I recently put a pair of 20" hookworm tires on my bike and I was wondering what pressure people were running them at. I had originally filled them with my hand pump and checked them with my pressure gauge i had only gotten them to 40psi so I used my compressor and got them up to 75psi but it felt like they were about to explode and they feel rock hard but they roll really nice. The tire says it is rated 85-110psi does anybody run these at that high a pressure?
