What does SAE 1205-1206 mean with regard to tire valve stems?
SAE stands for Society of Automotive Engineers and 1205-1206 is their standard for ozone resistance in valve stems. These standards are extremely important but not well enforced. Millions of substandard valve stems have entered the US with disastrous results and a huge recall. The results were badly cracked and dry rotted valve stems in use. Unfortunately many tire dealers are ignorant of SAE 1205-1206. Asking if the valve stems being installed meet this standard may be a good way to judge the competence of a tire retailer.
