TIRES
The most common cause of trailer tire trouble is under-inflation.
It is important, to always maintain correct air pressure as indicat-
ed by the tire manufacturer on the tire’s sidewalls. (Tire pressure
information may be listed on stickers elsewhere as a convenience,
but because tires may be replaced, the air pressure should always
be verified on the tire’s sidewall. If there is a dierence between
air pressure listings on labels, warning stickers and tire sidewalls,
always defer to the tire sidewall air pressure listing.)
Always check the air pressure when the tires are cold. Tires heat up
and the air pressure increases after traveling short distances. For
safety and convenience, inflate tires to the air pressure indicated
on the sidewall of the tire, but always carry a spare wheel and tire in
case of unexpected or sudden issues with a tire.
When trailer tires become worn or damaged, replace them with new
tires. An authorized MasterCraft dealer can help you.
ratchets, and similar tools can be useful for short-term emergency
repairs but are not appropriate tools for accurately checking lug
nut torque.
Keep a record of the date and approximate mileage when the lug
nut torque is checked. Note any lug nut(s) that lost torque. Investi-
gate the reason(s) if the lug nut torque is not maintained over more
than one retightening because this can be indicative of a possible
problem with the lug nuts, nut studs, wheels and/or hubs and that
should be corrected.
Contact an authorized MasterCraft dealer immediately if any
persistent lug nut loosening (or any other lug, wheel or axle
problem) occurs.
In the event of a wheel separating from the trailer during use, notify
an authorized MasterCraft dealer. Seek prompt professional as-
sistance in assessing the trailer and its gear, and retain but do not
reuse involved lug nuts, wheels and studs. Do not repair or service
the trailer yourself. Instead, call a trained, authorized MasterCraft
service technician.
Use the following pattern to tighten lug nuts. On first torquing pass
tighten to 45 ft.-lbs. On second pass tighten to 70 ft.-lbs. On third
pass tighten to 90 ft.-lbs. On fourth pass tighten to a reading be-
tween 110 ft. lbs-120 ft.-lbs. Follow the pattern shown in the photos
on the next page.
