When it comes to extra-wide wheels, many jurisdictions across Canada have laws that require mud flaps or fender extensions to reduce any wheel spray they produce. Some laws, such as in Alberta, specifically require any protection to extend to the outer edge of the tire. As a result, some vehicles contravene the law as soon as they leave dealers’ lots, even without modifications.
Still, the reasons for adding splash protections are simple: to prevent road spray from hitting vehicles approaching from behind. Water spray isn’t as pressing of an issue, but the more serious risks of paint-chipping and glass-cracking solid debris such as stones or gravel remain. Many modified truck and SUV owners don’t think they’ll ever be caught or ticketed for these infractions, and statistics tend to back them up. But if they’re pulled over for an unrelated issue, the chances of catching a bonus fine for extra-wide tires without splash protection climb. Avoid the risks altogether by mounting appropriate fender flares and mud guards when you install the wider tires.
