Using a space saver tire on a car with larger wheels can be tempting in a pinch, especially if you don’t want to shell out the money for a full-size replacement tire. However, it’s not recommended, and in some cases, it may even be illegal.
The first thing to consider is the size difference between the space saver tire and the original tire. A space saver tire is typically smaller in diameter than the original tire, and it’s designed to be used temporarily until you can get a proper replacement. This size difference can affect the handling and stability of your car, especially if you’re driving at higher speeds. The smaller tire can also affect the accuracy of your speedometer and odometer.
In terms of safety, using a space saver tire can also affect your car’s braking distance, which can be dangerous in emergency situations. The space saver tire is not designed to handle the same weight or load capacity as your original tire, and it may not provide the same level of traction and grip. This can increase your risk of hydroplaning or losing control of your car in wet or slippery conditions.
Another issue to consider is the legal implications of using a space saver tire on a car with larger wheels. In some countries and states, it’s illegal to use a space saver tire as a replacement for a full-size tire. If you’re caught driving with a space saver tire, you could face a fine or other penalties.
Overall, using a space saver tire on a car with 18-inch wheels is not recommended. While it may seem like a convenient solution, it can compromise your safety and put you at risk of legal trouble. If you need to replace a damaged tire, it’s best to get a full-size replacement as soon as possible. In the meantime, you can use the space saver tire to get to a nearby tire shop, but be sure to drive cautiously and avoid high speeds.
