Can a Tire Repaired by Vulcanization Be Used on Highways?
2 Answers
Tires repaired by vulcanization should not be used on highways because this method compromises tire quality, posing safety hazards that can affect driving safety. About Vulcanization Repair: Similar to patch repairs, vulcanization uses a sulfurization machine for high-temperature sulfurization treatment, making the patch adhere more firmly and lastingly to the damaged area of the tire. This method is suitable for tires with thicker sidewalls, such as those on large trucks, but not for the thinner tires of passenger cars. The sulfurization process requires precise temperature control. To avoid oversights or technical deficiencies during repair, other tire repair methods should be prioritized when a tire is damaged. Other Tire Repair Methods: Mushroom Plug Repair: Offers better and more durable results but is relatively more expensive and time-consuming, mainly suitable for larger damages. String Repair: Does not require tire disassembly or rebalancing, making it quick and convenient; however, it involves enlarging the damage, which may lead to air leakage over time. Patch Repair: Takes less time and is cheaper but less durable, suitable for smaller damages.
I've been commuting by car for years and have some insights on tire hot patching. Hot patching involves sealing punctures with high-temperature adhesive, which sounds sturdy but actually has hidden risks. At high speeds, tires heat up and deform, making the patched areas prone to detachment or cracking, which could lead to a blowout. I once saw a neighbor's car get into an accident after patching and driving on the highway—damage to the car and injuries weren't worth it. The location of the patch also matters; the middle of the tread is relatively stable, but near the sidewall is a no-go. If you really want to save money, it might work for short city drives, but forget about highways. Life is more valuable than money, so I advise against taking risks. Getting new tires is the way to go for peace of mind, especially if your car often travels at high speeds—safety first, no compromises.
