Is a cut on the tire shoulder serious?

[McRylee]

If it's just a small cut on the tread pattern, it's not a big issue. However, if the cut is deep, you should avoid driving on highways. If the damage is on the sidewall, it's strongly advised not to drive on highways. The tire sidewall is relatively thin, and once damaged, it cannot be repaired and must be replaced. Due to its thinness, any damage can easily lead to a blowout from the affected area. Tire replacement indicators: 1. Tire wear: Tires have tread wear indicators, which are slightly raised marks located at the bottom of the tread grooves. If the tread rubber wears down to the same height as these raised marks, the tire should be replaced immediately as continued driving is no longer safe. 2. Tire damage: Hitting a curb, falling into a pothole, or puncturing a nail can cause severe damage to the tire. A damaged tire might be repairable, but only a professional repair shop can accurately determine whether the tire can be repaired or needs to be replaced. 3. Tire aging: If you notice tread deformation or significant cracking, stop using the tire immediately and have it inspected by a professional repair shop to determine if it can continue to be used.
