In other words, do not drive on a deflated tire while the puncture is within the minor repair area (and is therefore repairable).

Inflation pressure maintains the shape of the tire while driving when that pressure is lost, the tire sidewall is going to be pinched between the wheel rim and the road, so continuing to drive will extend the damage beyond the minor repair area. One more thing concerning the sidewall is that you should avoid driving any further on a flat tire if you hope to salvage it. It’s unlikely that a repair patch applied here will stay in place for very long, and the tire will fail once again. Any attempts at making repairs in this area will potentially weaken the structural integrity of the tire.Īnother factor is that the sidewall experiences the most flex in the tire. When the tire is in daily operation, this section undergoes a significant amount of stress. The sidewall is off limits for a straightforward reason. More specifically, a puncture that falls outside the minor repair area is not eligible for fixing because of its proximity to the sidewall. Drivers have no other alternative than to invest in a brand-new tire. Moreover, if the size of the puncture is more than or equal to 6 mm in diameter, a repair isn’t permitted at all. The rules stipulate that tire repairs must stay within the central three-quarters of the tread, known as the “minor repair area.” The precise location of the puncture is also a deciding factor. There’s any sign of faulty repairs made in the past.There’s damage caused by an external object.The rubber is cracked, worn, or deteriorated.The structural integrity of the tire has been compromised or there is run flat damage.The tread depth is lower than the 1.6 mm legal limit.In summary, tire repair work is not permissible when: Regulations like these are necessary to ensure safety for all road users. The law in most countries has a strict definition as to the classification of repair materials, and the number of repairs permitted on a single tire. Tire repair is an option to explore rather than buying a brand-new tire, but drivers should know the full extent of what is legally permissible to have fixed. Okay, so you’ve got yourself a puncture in one or more of your tires.
