I would say purchasing a set of tyre protectors is worth while, as I recently found out when I fitted some front & rear brake pads for a member.
I was shocked to find the spring had broken, but at least the protector did it's job.
I removed the broken part of the spring, the rest of the spring was sitting in the protector & cup of the shocker, I informed the member to get the spring changed asap, as we know it is best to get the spring changed in pairs so if one cracks/or is broken then it is not going to be cheap.
