How to straighten tank tracks

I have a Tamiya King Tiger with rubber one piece tracks that curve. Straightening them by hand results in warping. Is there a way to get them flat and straight?

I take it you mean they curve when laid out flat. I seem to remember this happening when i used to use these tracks, if i recall correctly, they should be ok once they are applied to the vehicle. Thats all i can think of unless someone else has an idea.

Lay 'em on the clothes dryer (guidehorns up) and go build the model. After you’ve finished the rest of the tank a few days later the dryer will have been used many times (depending on how many times you use it). I’m thinking in a couple weeks or so they should be all relaxed and straight without having to do anything else. The longer you leave 'em, the better. This is a safe and GRADUAL method that works.
