RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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 indicato rs 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.
Vehicles with front and rear tires of the same size
Rotate the tires in the order shown. To equalize tire wear and extend tire life,
