EXPLANATORY NOTE 
A study conducted by an American Company called Safety Research and 
Strategies Inc., revealed that tires, like any other rubber product, have a limited service 
life regardless of tread depth and use. As tires age, the rubber components become harder 
and less elastic and the potential for corrosion and oxidation of the internal steel belts 
increases, even though there may be no external evidence of deterioration. 
The dangers of "aged" tires is a little known problem outside of the industry and 
one that is likely the cause of a significant number of tread separation problems. "Aged" 
tires are often unsuspectingly put into service after having served as a spare, stored in 
garages or warehouses, or simply used on a vehicle that is infrequently driven. In many 
instances these tires show no visible sign of deterioration, and absent any visible 
indicators, tires with adequate tread depth are likely to be put into service regardless of 
age. 
Two (2) major automobile manufacturers, Ford and DaimlerChrysler, in the 
United States ,began recommending tire replacement after six (6) years, regardless of 
mileage or remaining tread depth. Furthermore, a key study on this issue was conducted 
by the British Rubber Manufacturers Association, which includes many of the same tire 
companies that produce and sell tires in the Philippines and according to the study, 
association members strongly recommend that unused tires should not be put into service 


if they are over six (6) years old, and that all tires should be replaced ten (l0) years from 
the date of their manufacture. 
The proposed bill seeks to increase driver awareness as to the dangers of aged 
tires that are being sold and used in the country. It is also the intent of the proposed 
legislation to mandate all wholesale and retail points of sale to specifically inform buyers 
of the dangers of aged tires, the dates of manufacture of all tires sold, and to prohibit the 
sale of tires that are older than six (6) years.
