What is the reason why the spare tire of BYD F0 cannot be unscrewed?
2 Answers
If the spare tire of BYD F0 cannot be unscrewed, you can try dripping a few drops of oil on the screw first. If it still doesn't work, it is recommended to seek professional help for removal. The spare tire can only be used as a temporary replacement, with a maximum speed of no more than 80 km/h and a driving distance of no more than 100 kilometers. More details are as follows: 1. A full-size spare tire refers to a spare tire that is exactly the same size as the original car tire. It can provide a certain period of safe driving capability, but it occupies more space and is heavier. 2. A non-full-size spare tire is a spare tire that is slightly smaller in diameter and narrower in width than the regular tire. Since there are no specific mandatory regulations regarding the size of spare tires, many manufacturers choose a smaller size tire as the spare to save costs. For example, if the vehicle normally uses a 205 tire, the spare might be a 195, which is a non-full-size spare tire. 3. Compared to non-full-size tires, full-size tires occupy more space. Current car designs aim to be as lightweight as possible and maximize space utilization, so non-full-size spare tires are more common. 4. One advantage of using a non-full-size spare tire is that it occupies less space. Currently, some car brands use deflated tires as spare tires, which take up less trunk space. When such a tire is needed, it can be inflated using the onboard air pump provided with the car to ensure the spare tire's usability.
I had a similar issue with my BYD F0 before - the spare tire bolt wouldn't budge, mostly due to rust. Since the car's undercarriage is exposed, rainy or humid conditions can cause bolts to corrode and seize up. This is especially true for the F0's spare tire which is often stored under the trunk floor where water can accumulate and accelerate rusting. Also, you might be using an undersized wrench that can't deliver enough torque properly, causing the bolt head to strip. My advice: first soak the bolt threads thoroughly with WD-40 or similar rust penetrant, wait a few minutes for it to break down the rust, then use a quality wrench to apply steady pressure - don't jerk it violently or you might snap the bolt. Although spare tire components aren't used often, don't neglect them. During routine maintenance, wipe the bolts clean and apply some grease to prevent this headache. If you really can't loosen it, take it to a professional repair shop early to save yourself the frustration and potential tool damage.
