I agree with rregl0612, I think the way to go is find an alternative tire and foam and when Pro-line loses their grip on this market then they will fix this problem. I like Pro-line tires but I will not buy them anymore till the molded foams issue is fixed. They are the most expensive tire on the market plus you have to buy additional foams from OFNA to replace the ones that come with the Pro-line tires.
The molded foam insert is the foundation for the tire and it's a very unreliable foundation at this point.
