No. The preassembled wheels pop right off of the tires just like ones you would put together yourself. Trying to find a difference, I just disassembled one of the ones that is hard to disassemble (I needed a pen to pop the wheel out by using force). Testing against one of my regular 4624 tires, there is an obvious difference: The rubber is harder (they require more force to squeeze), which explains why it's harder to disassemble them from the wheels. Has anyone noticed a difference in material used for the 4624 tires through time? /Jan Rubber does harden over time as the plasticizers leak out. This hardening can be accelerated by heat and light as well as changes in the amount of cross-linking of the polymer chains. How old are these tires?
