Mercedes Benz 2007 sl 550 ユーザーズマニュアル

The treadwear indicator appears as a solid 
band across the tread.

Specified tire inflation pressures must be 
maintained. This applies particularly if the 
tires are subjected to extreme operating 
conditions (e.g. high speeds, heavy loads, 
high ambient temperatures).

Depending on the depth of the water layer 
on the road, hydroplaning may occur, even 
at low speeds and with new tires. Reduce 
vehicle speed, avoid track grooves in the 
road and apply brakes cautiously in the 
rain.

Although the applicable federal motor vehi-

cle safety laws consider a tire to be worn 

when the treadwear indicators (TWI) be-

come visible at approximately 

1

/

16

in 

(1.6 mm), we recommend that you do not al-

low your tires to wear down to that level. As 

tread depth approaches 

1

/

8

in (3 mm), the 

adhesion properties on a wet road are 

sharply reduced.

Depending upon the weather and/or road 

surface (conditions), the tire traction varies 

widely. 

G

Do not drive with a flat tire. A flat tire affects 

the ability to steer or brake the vehicle. You 

may lose control of the vehicle. Continued 

driving with a flat tire or driving at high 

speed with a flat tire will cause excessive 

heat build-up and possibly a fire.
