How many kilometers can a non-full-size spare tire be driven?
2 Answers
It is best not to exceed 160 kilometers with a non-full-size spare tire. Non-full-size spare tires usually have speed limit markings. When driving on highways, do not exceed 80 kilometers per hour, and the usage time of the spare tire should not be too long, not exceeding two hours. Relevant information about non-full-size spare tires is as follows: 1. A non-full-size spare tire refers to a spare tire that is slightly smaller in diameter and narrower in width than the regular tires. 2. The spare tire has different speed ratings and load indexes compared to the four normal tires of the vehicle and cannot be used as a replacement. The spare tire is only for temporary use.
Last time I went to the mountains and got a flat tire, using that undersized spare tire was nerve-wracking. The thing's a whole circle narrower than regular tires, making the steering feel floaty. The mechanic told me to keep it under 80 km/h and not exceed 160 km maximum. Speed shouldn't go over 50 mph either, otherwise the spare overheats easily. Most importantly - no highways! Even changing tires on the emergency lane requires hazard lights. I limped 100 km to the repair shop that time, and when they removed it, the tread pattern was already deformed from wear. Not exaggerating - even the spare's wheel rim is made of steel, which can easily damage the suspension on bumpy roads. Remember to keep tire pressure about 20% higher than the original tire, and find a tire repair shop within a few dozen kilometers.
