Trucker question ...tire related

Another draw back is the tires are expensive, when I dealt with the they were close to $1000 each. Many truckers would run them longer to save money, then bring then into the shop to get them "recapped" Or "retreaded" only to find that they ran them too far down and they got rock drilled from stones, causing the steel belts to rust, meaning that tire casing is now junk.....seen many Michelin tires do this, they are junk IMO anyway, nice ride but poorly built.
