I have a few nice old silk and cotton Clement tires that I have had in dry storage for about 30-35 years and I recently pulled them out thinking that they would be like new, but I find that the silk and cotton sidewalls seem a bit hard and the tires don't want to unfold without possible damage due to the stiffness. They are somewhat flexible and not totally stiff, but the sidewalls appear delicate and I don't want to rip or damage anything. Does anyone have any experience and suggestions on how to 'soften' them up so that they can be mounted safely? I was thinking to possibly soak them in water or something, but I know its always better to ask before blindly plodding ahead with an experiment. Or if I paint the sidewalls with 'tire life', will that soak in and accomplish my goal?
Thanks,
