When the gang pulls into the Steamtown Mall in Meredith's 1991-1996 Ford Aerostar XL, the hubcap on the rear driver's side wheel is missing. This is the same wheel which gets a puncture in its tire later in the episode. The hubcap was already missing before the blowout, prepped for the upcoming roadside scene.
While on the phone with Pam just after the work day ends, Jim asks her how many words per minute the average person types. Pam replies that she types 90 WPM, and guesses the average person types 70 WPM. Jim replies that he types 65 WPM, which Pam calls "respectable". The average person types between 38 and 40 WPM, what translates into between 190 and 200 characters per minute (CPM).
