SUMMER TIRES
Your Ford vehicle may be equipped with summer tires to provide
superior performance on wet and dry roads. Summer tires do not have
the Mud and Snow (M+S or M/S) tire traction rating on the tire side
wall. Since summer tires do not have the same traction performance as
All-season or Snow tires, Ford does not recommend using summer tires
when temperatures drop to approximately 40°F (5°C) or below
(depending on tire wear and environmental conditions) or in snow/ice
conditions. Like any tire, summer tire performance is affected by tire
wear and environmental conditions. If you must drive in those
conditions, Ford recommends using Mud and Snow (M+S, M/S),
All-season or Snow tires.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:
Base Curb Weight – is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight – is the weight of your new vehicle when you
picked it up from your authorized dealer plus any aftermarket
equipment.
