Mercedes Benz 2004 c 320 Manual De Usuario

The following text is published as required 
of all manufacturers of passenger cars 
under Title 49, Code of U.S. Federal 
Regulations, Part 575 pursuant to the 
“National Traffic and Motor Vehicle Safety 
Act of 1966”.

Quality grades can be found, where 
applicable, on the tire sidewall between 
tread shoulder and maximum section 
width. For example:

All passenger car tires must conform to 
federal safety requirements in addition to 
these grades.

The tread wear 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

) times as well on 

the government course as a tire 
graded 100. The relative performance of 
tires depends upon the actual conditions 
of their use, however, and may depart 
significantly from the norm due to varia-
tions in driving habits, service practices 
and differences in road characteristics and 
climate.

The traction grades, from highest to lowest 
are AA, A, B, and C. Those grades 
represent the tire’s ability to stop on wet 
pavement as measured under controlled 
conditions on specified government test 
surfaces of asphalt and concrete. A tire 
marked C may have poor traction 
performance.

The traction grade assigned to this tire is 
based on straight ahead braking traction 
tests, and does not include acceleration, 
cornering, hydroplaning, or peak traction 
characteristics.
