I cut into one of mine a little more than an 1/8th inch with a cut-off wheel, while clumsily doing some exhaust work. I've wheeled it several times since then with no problems. Heavy bumper on the front too. I bought an extra set of T-bars in case it let go, but I don't see it happening.

when looking for a container to hold drained brake fluid, find a container that is different from the beverage you are currently consuming.
