At 25 thousand kilometers, the tires on a 2023 Onix still have plenty of life left, so your neighbors who say they're holding up probably have a point. What matters is checking the tread depth (make sure it's not too worn) and the overall condition of the rubber, looking for cracks, bulges, or uneven wear that could indicate an alignment problem. A good rule of thumb is that when the tread gets really low or if you notice the car slides on wet roads or vibrates when braking, that's when you should change them, but that usually happens after 40 thousand to 60 thousand kilometers depending on how you drive. For now, check the pressure and alignment regularly, but there's no rush to change them yet.
