Tire Pressure
The following is to be used as a general guide for tire inflation. Figures can vary depending on specific brand of tire used. It is important
that tires are inspected before and after unit is loaded. Start with the minimum pressure indicated. The tire should stand up with no
side wall buckling or distress as tire rolls. Do not exceed maximum recommended tire pressure. 235-85-R16 tires are standard on the
SpeedTender Pro and should be inflated to 80 psi. J&M also recommends rotating your tires front to back (not side to side) every 1,200
miles or 12 months (whichever comes first) for longer tire life. The image below is a troubleshooting chart used to ensure the tires wear
evenly.
Tightening Lug Nuts
Torque 9/16"-18 lug nuts on wheels to 170 ft-lbs after the first 10, 25, and 50 miles of driving, then recheck torque every 50 hours or every
year, whichever comes first. Failure to do so may damage wheel nut seats. Once seats are damaged, it will become impossible to keep
nuts tight.
