Scion iM_U (12J49U)
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “” mark,
etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.

To equalize tire wear and extend
tire life, Scion recommends that
tire rotation is carried out at the
same interval as tire inspection.
