>>2060While this is true, there are a few things to note.
One, trucks ( I'm guessing you're talking about 18-wheelers ) aren't allowed to use Retreads on their steering wheels.
Two, those tires are designed with being re-capped in mind, the structure of the tire is engineered to handle it, but only so many times ( I'm not sure on the number, but there is a limit ).
Three, if any of the re-capped tires go, because of the rules they're nearly always dualies. So you've got an extra tire beside the one that let go to get the truck off the road safely.
