Where to Place the Jack When Changing a Tire?
3 Answers
The vehicle body bottom has dedicated support points for the jack, usually located on the inner side of the side skirts, approximately 200mm behind the front wheels and 200mm in front of the rear wheels. Below is relevant information:1. Tire Change Considerations: The new tire must match the specifications of the previous one and be identical to the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. Tires with seemingly symmetrical treads actually have a specific direction; incorrect installation may lead to uneven wear. When installing the tire, ensure the side with numbers faces outward toward the wheel hub. However, different manufacturers may use varying labeling methods, such as some brands marking "OUTSIDE" on the tire sidewall. After installation, wheel balancing is essential. Inflate the tire to the maximum allowed pressure before reducing it to the manufacturer's recommended standard pressure.2. Tire Maintenance: To ensure tire mileage and performance, conduct monthly checks on tire pressure, wear uniformity, and any damage. Proper tire pressure enhances tire performance and fuel efficiency. Underinflation is a leading cause of tire failure, potentially causing severe cracking, component separation, or blowouts. It reduces load capacity, leads to excessive sidewall flexing, increases rolling resistance, and causes heat buildup or mechanical damage. Overinflation makes tires harder, resulting in an uncomfortable ride and unnecessary vibrations, while also increasing the risk of impact damage.
As an experienced driver who frequently changes tires, I've learned that the jack must be placed at the vehicle's designated jacking points. These are typically located on the side of the chassis near the wheels, such as on the sill beam or reinforced points on the frame, marked by triangular notches or arrow indicators. Never jack up the car at random spots like door edges or plastic parts, as this can cause body deformation or even jack collapse, posing serious safety risks. I've noticed that positions vary slightly across models—sedans often have points inside the wheel arches, while SUVs may position them higher—so always consult the owner's manual first for certainty. Tire-changing steps: park on level ground, engage handbrake, set warning triangles, locate the point, and lift steadily. Remember to place the wheel hub underneath as a safety buffer against accidents. I prioritize safety—install the spare tire swiftly and securely. Also, check tire pressure and the spare's expiration date to avoid follow-up hassles. Familiarize yourself with these points during routine maintenance to minimize panic during emergencies.
I'm a design enthusiast passionate about cars, and studying vehicle structures excites me. The jacking point is actually a stroke of engineering brilliance—automotive engineers reinforce specific spots on the chassis, typically metal beams near the suspension, to bear pressure without deformation. Locations vary by model: compact cars often have them along the sill, while SUVs position them on frame protrusions. You can spot them near wheel arch edges or refer to manual diagrams. The logic is straightforward: avoid damaging brake lines or exhaust systems. Personally, I rely on visual cues—look for raised notches or grooves along the vehicle’s flank. Pro tip: invest in a high-quality jack (hydraulic ones offer superior stability). Never compromise safety—ensure level ground and secured wheels before lifting. Bonus insight: check spare tire condition to prevent dry rot; improper use risks body dents or costly repairs. Small knowledge, major impact.
