Things to know about tire pressure:
1. A large imbalance in air pressure from left to
right on the front tires will put undue strain on the
over-running clutch in the front differential when
operating in four-wheel-drive mode on paved
surfaces.
2. A large imbalance in air pressure from left to
right on the front tires will cause the steering to
pull in the direction of lower pressure.
3. A large imbalance in air pressure from front to
rear will effect the lead-lag ratio, placing undue
strain on the drive system when operating in
four-wheel-drive mode on paved surfaces.
4. Tire pressure can be adjusted within the recom-
mended range of 14-22 psi (.97-1.52 bar.).
5. Higher tire air pressure is good when:
• The vehicle is operated on firm but bumpy ter-
rain.
• The vehicle is consistently operated with heavy
loads.
• The vehicle is consistently operated near the
upper end of its speed range.
6. Lower tire air pressure is good when:
• The vehicle is operated on soft ground like mud
or sand, where more traction is required.
• The vehicle is used to carry delicate contents
that would benefit from a softer ride.
Tire size and condition.
1. Tire wear indications:
• Because the vehicle is equipped with trail tires,
tire wear will be accelerated if the vehicle is used
heavily on paved surfaces.
• Front tread blocks that appear “smeared” out-
ward on the font surface of the tire indicate a
toe-in condition.
• Front tread blocks that appear “smeared” inward
on the front surface of the tire indicate a toe-out
condition.
• Tread blocks that are worn unevenly in a “scal-
loped” pattern indicate worn ball joints, worn
steering components, or a worn dampers.
• Because of the round-shouldered design of the
trail tires, camber angle issues may not be
noticeable from tire wear patterns.
• The more the vehicle is used on paved surfaces,
the more pronounced the wear patterns will be.
2. Tire size: See Figure 4.2.
• Original Equipment is:
Carlisle brand
AT489 model direction-specific trail tire
Front: 26x10.00-12 size
Rear: 26x11.00-12 size
Other tires may be used in future production.
• Do not use mis-matched tires.
• When viewed from the top front, the tread blocks
should sweep outward and rearward from the
center of the tread.
