2019 LINCOLN MKC wheel size

•Use 10 mm cables or chains only on frontaxle with 235/50R18 tires.
•Not all S-class snow chains or cablesmeet these restrictions. Chains of thissize restriction will include a tensioningdevice.
•The snow chains or cables must bemounted in pairs on the front axle.
•Do not use chains or cables on235/45R19, 245/45R19 and 255/40R20tires.
•Install cables securely, verifying that thecables do not touch any wiring, brakelines or fuel lines.
•When driving with tire cables do notexceed 30 mph (48 km/h) or themaximum speed recommended by thechain manufacturer, whichever is less.
•Drive cautiously. If you hear the cablesrub or bang against the vehicle, stop andretighten them. If this does not work,remove the cables to prevent vehicledamage.
•Remove the cables when they are nolonger needed. Do not use cables on dryroads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctly maintaintire pressures could increase the risk of tirefailure, loss of control, vehicle rollover andpersonal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.

If you get a flat tire when driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have a flat serviced by an authorized dealerin order to prevent damage to the tirepressure monitoring system sensors. SeeTire Pressure Monitoring System (page 332).Replace the spare tire with a road tire assoon as possible. During repairing orreplacing of the flat tire, have the authorizeddealer inspect the tire pressure monitoringsystem sensor for damage.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increased riskof loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,then it is intended for temporary use only.This means that if you need to use it, youshould replace it as soon as possible with aroad wheel and tire assembly that is thesame size and type as the road tires andwheels that were originally provided by us.If the dissimilar spare tire or wheel isdamaged, it should be replaced rather thanrepaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tire assemblythat is different in brand, size or appearancefrom the road tires and wheels and can beone of three types:
1. T-type mini-spare: This spare tire beginswith the letter T for tire size and may haveTemporary Use Only molded in the sidewall.
2. Full-size dissimilar spare with label onwheel: This spare tire has a label on thewheel that states: THIS WHEEL AND TIREASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar sparetires listed above, do not:
•Exceed 50 mph (80 km/h).
•Load the vehicle beyond maximumvehicle load rating listed on the SafetyCompliance Label.
•Tow a trailer.
•Use snow chains on the end of thevehicle with the dissimilar spare tire.
•Use more than one dissimilar spare tireat a time.
•Use commercial car washing equipment.
•Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listedabove at any one wheel location can lead toimpairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•All-wheel driving capability
3. Full-size dissimilar spare without labelon wheel

Wheels and Tires

When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 70 mph (113 km/h).
•Use more than one dissimilar sparewheel and tire assembly at a time.
•Use commercial car washing equipment.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
The usage of a full-size dissimilar sparewheel and tire assembly can lead toimpairment of the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
•Wet weather driving capability.
•All-wheel driving capability
When driving with the full-size dissimilarspare wheel and tire assembly additionalcaution should be given to:
•Towing a trailer.
•Driving vehicles equipped with a camperbody.
•Driving vehicles with a load on the cargorack.
Drive cautiously when using a full-sizedissimilar spare wheel and tire assembly andseek service as soon as possible.

Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign materials present on the mounting surfaces of thewheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that attach therotor to the hub so they do not interfere with the mounting surfaces of the wheel. Installing wheels without correct metal-to-metal contact atthe wheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while your vehicle is in motion, resulting in lossof vehicle control, personal injury or death.
Ib-ft (Nm)*Bolt size
100 (135)M12 x 1.5
*Torque specifications are for nut and bolt threads free of oil, dirt and rust. Use only Ford recommended replacement fasteners.
Retighten the lug nuts to the specified torque within 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing aflat tire, wheel removal).
