NISSAN 2015 GT R - Owner's Manual - Manual (Page 342)

Do not tow a trailer with your vehicle. Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle behind a recreational vehicle, such as a
motor home.
DO NOT tow the GT-R with all four wheels on
the ground (flat towing). Doing so WILL
DAMAGE internal transmission parts. Tow the
GT-R with all four wheels off the ground.

DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half (1
1/2) times as well on the government course as
a tire graded 100. The relative performance of
tires depends upon actual conditions of their
use, however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road char-
acteristics and climate.
