2005 FORD GT four wheel drive

7.H: Indicates the tire ’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.
Note: You may not find this information on all tires because it is not
required by federal law.
Letter rating Speed rating - mph (km/h)
M 81 mph (130 km/h)N 87 mph (140 km/h)
Q 99 mph (159 km/h)R 106 mph (171 km/h) S 112 mph (180 km/h)
T 118 mph (190 km/h)
U 124 mph (200 km/h)
H 130 mph (210 km/h) V 149 mph (240 km/h)
W 168 mph (270 km/h) Y 186 mph (299 km/h)
Note: For tires with a maximum speed capability over 149 mph (240
km/h), tire manufacturers sometimes use the letters ZR. For those with
a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
8. U.S. DOT Tire Identification Number (TIN): This begins with the
letters “DOT ”and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code designating where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are identification codes used for traceability. This
information is used to contact customers if a tire defect requires a recall.
9. M+S or M/S: Mud and Snow, or
AT: All Terrain, or
AS: All Season.

Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a Ford or Lincoln/Mercury dealer. Front wheel drive (FWD) vehicles
and those with an independent rear suspension (if equipped) may
require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire rotation
Because your vehicle is equipped with unique larger tires on the rear
wheels, you can only rotate tires side to side. You must not rotate tire in
a crisscross pattern or front to rear. If you notice that the tires wear
unevenly, have them checked.
Rotating your tires at the recommended interval (as indicated in the
Scheduled Maintenancechapter) will help your tires wear more evenly,
providing better tire performance and longer tire life. Unless otherwise
specified, rotate the tires approximately every 5,000 miles (8,000 km).
• Tire rotation
Sometimes irregular tire wear can be corrected by rotating the tires.
Note: If your tires show uneven wear ask a qualified technician at a
Ford or Lincoln/Mercury dealership to check for and correct any wheel
misalignment, tire imbalance or mechanical problem involved before tire
rotation.
Note: After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
