Along with the potential for the rubber hose to get a hole rubbed in it, if a tire blows it tends to destroy the brake lines that are on the outside of the frame. Repositioning the lines to the inside minimizes this potential. Doesn't happen often, but enough times to get mentioned on the DRV forums. This is mostly with the MorRyde IS installs, but still can happen on the standard leaf spring setups. In the 10 years I had the '05, never had the hose problem or a blowout, nor the 3 years I had the '15, but had the '15 repositioned after reading about some having all braking lost due to a blowout.
