What is the expected life span of these tubes? I noticed that mine have started to bow/arch in the center. With the loading of splits, I have bumped into this tube. Now, I looked at it and its actually cracked and there is a ~ 1" square area that is just missing.
It looks pretty easy to swap...but what is the normal life span?
Thank you
