4.2.1 General Information
Most vehicles require installation of alternate wheels and tires to properly align the vehicle’s
track width to the rails. DMF offers Wheel Modification Kits for many popular chassis models for
use on standard gage rail. Specific components and part numbers vary by application, but most
wheel modification kits include appropriate wheel adapters and rims, steering stops, and TPMS
sensors.
4.2.2 Wheel Adapters and 19.5” Rims
Wheel adapters and 19.5” rims are used to align the track width of the vehicle with the rails.
Wheel adapters typically bolt onto the factory wheel studs and use the factory lugnuts.
19.5” rims are typically p aired with 225/70R19.5 or 245/70R19.5 heavy duty truck tires. It is
important to have the new wheel and tire combination accurately balanced. Tire installation
facilities that specialize in serving commercial truck customers may be better equipped to
mount and balance these types of tires.
4.2.3 Steering Stops
Hyrail vehicles usually require the installation of steering stops. These prevent the wheels and
tires on vehicles with narrowed track widths from contacting the frame, brake lines, or
suspension components during turns. After installation of steering stops, a thorough check
should be performed to verify there are no component interference, particularly with the
steering wheel in both extreme positions.
 STEERING STOP INSTALLATION MUST BE VERIFIED ON EVERY VEHICLE
BEFORE IT IS OPERATED ON THE HIGHWAY! Incorrectly installed Steering
Stops can cause serious tire damage and create a hazard for anyone operating
the vehicle.
 INSTALL STEERING STOPS BEFORE MOVING THE VEHICLE! If you don't, you can
cause serious tire damage and create a hazard for anyone operating the
vehicle.
Installation
 Verify that the steering stops limit the wheels or tires from any contact with frame, sway
bar, wheelhouse, suspension etc. DMF recommends at least 1/8" clearance from any
fixed obstruction to the wheel or tire in any suspension position.
 To check clearance in the normal suspension position, jack the vehicle under the axle,
suspension or upright until the tire clears the ground.
 To check clearance in the drooped position, jack the vehicle under the frame, cross-
member or body jack point until the tire clears the ground.
 Check the steering clearance on both sides. Many suspensions are not entirely
symmetrical.
