Why does the car feel bumpy after installing new tires?

What is the tire model of the Mercedes-Benz C260L?

The tire sizes for the Mercedes-Benz C260L are 225/50R17 and 225/45R18 models. Tire model markings: Most tire model markings look like: 215/70R15, where the numbers represent the following: 215 indicates the tire section width in mm, generally ranging between 145-285mm in 10mm intervals; 70 is the aspect ratio, representing the ratio of the tire sidewall height to the tire section width, with 70 meaning 70%. Typically, the aspect ratio ranges from 30%-80%. Normally, ordinary sedans should not use tires with an aspect ratio >75%, while luxury cars and high-performance sports cars recommend tires with an aspect ratio <60%; R stands for Radial, indicating the tire has a radial structure, and 15 is the rim diameter in inches. Bias-ply tire markings: If a tire is marked like: 6.00-12, it indicates that it is not a radial tire but a bias-ply tire. Such tires are rarely seen in passenger cars today due to their poor safety, load capacity, and high-speed stability, and are only used in some low-end off-road vehicles and heavy-duty trucks.

What Causes the ABS Yellow Light to Illuminate in Trucks?

ABS warning lights can indicate various conditions, each with distinct causes and solutions as outlined below: Condition 1: ABS warning light remains constantly illuminated (most common). Cause 1: The ABS speed sensor's sensing area is contaminated by mud, sludge, or other debris, impairing its ability to detect wheel speed signals. This prevents the ABS computer from determining vehicle speed or wheel slip rates, consequently disabling proper brake modulation. Solution: Clean the speed sensor and adjust its clearance with the tone ring to restore normal function. Cause 2: Loose wiring connections or poor ABS relay contact causing signal interference. Solution: Inspect all wiring connections and resecure any loose terminals. Condition 2: ABS warning light intermittently illuminates but extinguishes during acceleration. Cause: Electrical system voltage drops below 10.5V when multiple accessories are operating. The light extinguishes when engine RPM increases voltage. Possible poor power supply connections or grounding issues. Solution: Check battery specific gravity, charging system, and power supply connections (including voltage relays). Condition 3: ABS light remains illuminated after engine start until IGFF position. Cause: Poor grounding of ABS hydraulic valve body; faulty wiring connections; or ABS computer malfunction. Solution: Loosen and retighten valve body ground screws (clean contact surfaces if necessary); inspect connector gaps; replace ABS/ASR computer if needed. Condition 4: ABS warning light activates during highway driving. Cause: Significant discrepancy between front/rear wheel speed calculations by ABS computer; incorrect tire or wheel specifications. Solution: Verify proper tire/wheel specifications as indicated on fuel door placard. Condition 5: Intermittent ABS warning light activation. Cause: Maladjusted brake light switch or internal switch contact failure. Solution: With engine running, depress brake pedal while manually pushing switch lever downward, then release pedal to reset; replace switch if necessary. Important: When the ABS warning light illuminates, discontinue driving immediately. ABS failure compromises wheel anti-lock capability during emergency braking, potentially causing uncontrolled skidding and eliminating the driver's ability to decelerate or maintain vehicle control, creating significant safety hazards.

Can a Broken Car Clip Be Repaired?

If a car clip is broken, it can be repaired at a repair shop or auto beauty shop. You can also fix it yourself using tools. Here are the relevant details: 1. Repair Method: Use a heat gun to melt and flatten the damaged part of the clip. Secure a new bumper clip and reattach it using welding rods or sticks. 2. Additional Information: Bumper clips are devices used to secure the bumper. If one or two are missing and it doesn't affect the bumper gap, replacement may not be necessary. Each time the bumper is disassembled or reinstalled, the technical requirements may vary, which can lead to increased gaps and affect the appearance.

Why is one side of the air suspension higher than the other?

During driving, issues may arise with the air suspension. Here are the detailed explanations: 1. When the air suspension system malfunctions, the following symptoms may occur: the vehicle's air suspension sags, with the wheels and wheel arches touching; the vehicle may exhibit uneven height on either side; the air suspension system warning light illuminates. 2. Common causes of air suspension system failures include: leaking connecting pipes; damaged body height sensors or acceleration sensors; damaged shock absorbers leaking air; faulty air compressor; issues with the control unit, wiring, or distribution valve.

Reasons for Poor Car Idling

Reasons for poor car idling: 1. Intake manifold or various valve leaks; 2. Excessive carbon buildup in the throttle body and intake passages; 3. Malfunction of idle air actuators; 4. Fuel injector failure; 5. Fuel pressure issues; 6. Incorrect fuel injection quantity; 7. Spark plug and high-tension wire faults. Methods to check poor car idling: 1. Inspect all intake system pipe connections, vacuum hoses, exhaust gas recirculation system, and fuel vapor recovery system for leaks; 2. Check whether the idle control valve is functioning properly; 3. Examine electrodes for wear or carbon buildup and verify the spark plug electrode gap is normal.
