Tiff's signature racing helmets are orange because he raced junior powerboats as a teen, and in that sport, orange helmets were mandatory for all participants.
Tiff's first proper racing car, a Formula Ford Lotus 69F, was actually won in a contest sponsored by Autosport Magazine in 1971.
As of 2007, Tiff resides in Salisbury with his family, which includes his wife (Patsy) and their three sons (Jack, Harry, and George).
Along with members of the Top Gear cast, Tiff co-hosts MPH, a popular live automotive showcase held in England every autumn.
In November of 2006, Tiff was cleared of a speeding violation after providing evidence that he did not receive proper notification of the wrongdoing in the mail and claiming he did not know who was driving his car that day.
Tiff has provided voiceovers for a few racing videogames, including TOCA Touring Car Championship, Test Drive: Le Mans, and Le Mans 24 Hours.
Tiff gained his nickname from his older brother, who couldn't pronounce Timothy and kept saying "Tiff" instead.
Tiff: If someone toots their horn at you, the automatic response is to give them the finger, even though you know you're in the wrong. If we all drove in a more relaxed mood, the roads would be a safer place.
Tiff: I haven't owned a car since 1982. I don't need to, I've always got a test car to drive. People always ask me what I've got in my garage, I've got nothing! I built myself a garage, but the only things in it are a lawnmower and a quadbike.
Tiff: Concept cars are something I never take too seriously. They're fun for the designers, but more often a frustration for us drivers who never get to ever use them.
