DIAMOND BAR, Calif. (March 25, 2003)—In monthly online polls conducted by the Specialty Equipment Market Association (SEMA), 13 percent of respondents admitted they never check their tire pressure and 16 percent don't know they have to rotate their tires.
While the tire pressure poll was run on SEMA's consumer Web site in November 2001, the subsequent tire rotation question was posed last month. SEMA would not say how many total respondents participated in the voluntary poll, but a spokeswoman said an average of 68,852 unique visitors a month visited the site, based on data from the past four months.
Thirty-nine percent of respondents checked their tire pressure monthly, with another 20 percent checking it every week. Thirty-nine percent of respondents said they rotated their tires according to their owner's manual, with an additional 20 percent rotating them at every oil change. Also, 25 percent said they rotate the tires only when they notice uneven tire wear.
