2.3 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. 80 psi is the cold rating on the tire that is standard for the Speed Tender. J&M also
recommends to rotate your tires front to back (not side to side) every 1,200 miles or 12 months (whichever comes
first) for longer tire life. Figure 2.3 below is a troubleshooting chart used to ensure the tires wear evenly.
2.4 Tightening Lugnuts
Torque lug-nuts on new and removed wheels to 350-375 ft. lbs. after the first 10, 25, and 50 miles of driving,
then recheck torque every 50 hours or every year, whichever comes first. Always tighten
lug-nuts in the following sequence.
