14.7 Tire Pressure, Nitrogen-Filled Tires
As both a convenience and a technical benefit, AYRO res are filled with dry nitrogen, indicated
by the green caps included on the Schrader re valves. Nitrogen fills have several advantages,
including beer thermal stability (nitrogen expands less in hot weather and contracts less in cold
weather), lower rate of leakage than air (slower loss of re pressure), and improved corrosion
prevenon. Nitrogen filling is readily available for most owners, but it is acceptable to fill AYRO
res with regular compressed air if nitrogen filling is unavailable. Nitrogen fills are typically
available at many car dealerships, re distributors, and mulnaonal chains (Costco, Sam’s Club,
and many larger Walmart centers).
NOTE: Regular air is composed of roughly 78% nitrogen and just over 20%
oxygen, with the remainder including water vapor, argon, and
miscellaneous gases.
NOTE: Underinflated res can reduce vehicle range by approximately 0.2%
for every 1 PSI drop in re pressure and contribute to faster wear
and increase potenal for re failure. Ensure that all your res are
properly inflated for best performance.
AYRO res are a soer compound designed for lower operang pressures than standard
automove res. This combinaon makes it possible to drive on golf course turfs without
damaging the grounds.
WARNING: Improper re pressure can cause loss of control resulng in
severe injury or death.
Proper re pressure is essenal to the safe and comfortable operaon of your vehicle. Check
re pressure daily, or before each use of the vehicle. (Tire pressure on the AYRO re is 20 psi.)
Recommended re pressures are shown on the manufacturer’s label on your vehicle or the
specificaons secon beginning on page
77. Tires are factory-filled with nitrogen.
Aer inspecng or adjusng the re pressure, always reinstall the
valve stem cap. This will prevent moisture and dirt from entering the
valve stem, which could cause damage.
14.8 Tire Tread Depth
Any accelerated wear of res may be an indicator of improper alignment or poor driving habits.
Your authorized AYRO Dealer can assist.
Always replace res when tread depth is worn to 1/8” (3 mm) or less.
