Highway Hazards
No matter how carefully you drivethere’s always the possibility thatyou may eventually have a flat tireon the highway. Drive slowly to theclosest safe area out of traffic.This may further damage the flattire, but your safety is moreimportant.
If you feel a sudden vibration orride disturbance while driving, oryou suspect your tire or vehiclehas been damaged, immediatelyreduce your speed. Drive withcaution until you can safely pulloff the road. Stop and inspect thetires for damage. If a tire is
under-inflated or damaged,deflate it, remove wheel andreplace it with your spare tire andwheel. If you cannot detect acause, have the vehicle towed tothe nearest repair facility or tiredealer to have the vehicleinspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to becomemisaligned or cause damage toyour tires. If your vehicle seems topull to one side when you’redriving, the wheels may be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer. Front-wheeldrive vehicles and those with anindependent rear suspension mayrequire alignment of all fourwheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involved
before tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to thevehicle requirements.
105Motorhome (TY3) , enUSAWheels and Tires

Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) will helpyour tires wear more evenly,providing better tire performanceand longer tire life.
Dual rear wheel drive vehicle - sixtire rotation
If your vehicle is equipped withdual rear wheels it isrecommended that the front andrear tires (in pairs) be rotated onlyside to side. We do notrecommend splitting up the dual
rear wheels. Rotate them side toside as a set. After tire rotation,inflation pressures must beadjusted for the tires newpositions in accordance withvehicle requirements.
Sometimes irregular tire wear canbe corrected by rotating the tires.
USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index, speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath. Additionally, the use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you needto use cables, it is recommended that steelwheels (of the same size andspecifications) be used, as cables may chipaluminum wheels.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle
•Use only SAE Class S chains.
106Motorhome (TY3) , enUSAWheels and TiresE161439

•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
