Accelerated aging techniques are applied to a tire to evaluate the level of oxidation that takes place over a specified period of time. Smithers’ equipment capabilities include a variety of environmental chambers, including 4 large oven chambers with a range of 65°C - 70°C.

Government testing proved that migrating oxygen attacks the boundary layers of a tire. In order to replicate that effect, our standard testing protocols include:
  • Inflating tire with a 50% oxygen / 50% nitrogen mix (50/50 mix)
  • Aging for one to eight weeks, based on protocol specifications
  • Purging and reinflating tire with 50/50 mix at regular intervals
  • Completing endurance test protocols on tires after oven aging
In addition, custom test protocols can be made to meet a client’s specific requirements.
