Yes, it is possible to change the tyre size in Hyundai Exter. However, there are a few things to keep in mind before you do so. First, you need to make sure that the new tyre size is compatible with the Exter's suspension and brakes. If you choose a tyre size that is too large or too small, it could affect the handling of the car and even cause damage to the suspension or brakes.Second, you need to make sure that the new tyre size is within the limits specified by Hyundai. The Exter's tyre size is 165/70 R14. This means that the tyre's width is 165 millimetres, the aspect ratio is 70, and the rim size is 14 inches. You can change the tyre size to a different width, aspect ratio, or rim size, but it must be within the limits specified by Hyundai.Third, you need to make sure that the new tyres have the same load index and speed rating as the original tyres. The load index is a measure of the tyre's load carrying capacity, and the speed rating is a measure of the tyre's maximum speed. If you choose tyres with a lower load index or speed rating, it could affect the safety of the car.If you are considering changing the tyre size in your Hyundai Exter, it is best to consult with a qualified tyre dealer. They will be able to help you choose the right tyre size for your car and make sure that the tyres are compatible with the Exter's suspension and brakes.Here are some of the benefits of changing the tyre size in your Hyundai Exter:Improved handling: A wider tyre can improve the handling of the car, making it more responsive and stable in corners.Increased comfort: A taller tyre can provide a more comfortable ride, especially on rough roads.Improved fuel economy: A lower aspect ratio tyre can improve the fuel economy of the car.However, there are also some potential drawbacks to changing the tyre size in your Hyundai Exter:Increased cost: Tyres can be expensive, so changing the tyre size can increase the cost of owning the car.Reduced performance: A larger tyre can reduce the performance of the car, especially in terms of acceleration and top speed.Reduced ground clearance: A taller tyre can reduce the ground clearance of the car, making it more susceptible to bottoming out on rough roads.Overall, whether or not to change the tyre size in your Hyundai Exter is a personal decision.
