What does R15 on tires mean?

R is the abbreviation of Radial, indicating that the tire has a radial structure; 15 is the outer diameter size of the rim, meaning it is 15 inches. Tire data: Generally, the width of tires ranges between 145—285mm, with intervals of 10mm; the aspect ratio of tires is between 30%—80%. Under normal circumstances, ordinary sedans should not use tires with an aspect ratio greater than 75%, while luxury cars and high-performance sports cars are recommended to use tires with an aspect ratio less than 60%. Tire classification: Tires can mainly be classified by structure, tread pattern, type, and climate. Tires can be divided into radial tires and bias-ply tires based on internal structure. Based on surface tread patterns, tires can be categorized into rib pattern tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires.

Can Burning Engine Oil Damage the Catalytic Converter?

Burning engine oil can damage the catalytic converter, which serves as an external purification device installed in the vehicle's exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Maintenance tips for the catalytic converter: 1. Avoid using leaded gasoline; 2. Avoid prolonged idling; 3. Do not let the engine speed fluctuate rapidly; 4. Avoid excessively delayed ignition timing; 5. Do not test for spark by pulling out the high-voltage wire for extended periods; 6. When measuring cylinder compression, disconnect the fuel pump's central control connector; 7. If any cylinder is found to be malfunctioning, stop the vehicle promptly to inspect and rectify the issue; 8. Do not disassemble it arbitrarily—ensure any replacement matches the engine specifications.

Driving Techniques for Slippery Conditions on Snowy Uphill Roads

Driving techniques for slippery conditions on snowy uphill roads are as follows: 1. Use snow tires, which have specialized tread patterns designed to effectively enhance traction on snow-covered roads and improve driving safety. 2. Control your speed; snowy roads are very slippery, and the sensitivity of brake control will decrease. Maintain a steady speed and avoid sudden braking. 3. Make reasonable use of gears. Maintain a low gear when going uphill, as driving in a low gear allows the vehicle to pass smoothly on slopes. When going downhill, avoid coasting in neutral and do not slam on the brakes. 4. If your vehicle has a snow mode, activate it. The computer will control the engine to output power more gently, further preventing wheel spin when starting on icy or slippery surfaces.

What are the reasons for OBD failure?

The reasons for OBD failure are: 1. caused by an outdated OBD system; 2. due to malfunctioning sensors in the OBD system; 3. engine failure. OBD stands for On-Board Diagnostics, which continuously monitors the vehicle's operating conditions during operation, working in conjunction with numerous sensors to monitor the engine's operating status and the performance of the exhaust treatment system in real time. OBD monitors the engine, catalytic converter, particulate filter, oxygen sensors, emission control system, fuel system, EGR system, and related components in real time. It connects to the ECU with various emission-related component information. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the malfunction indicator lamp to inform the vehicle owner.

Can Tires Float on Water?

Yes, tires are made of rubber, and the density of rubber is lower than that of water, so they will definitely float. Below is relevant information: Introduction: Car tires are one of the important components of a vehicle. They directly contact the road surface and work together with the car suspension to mitigate the impacts encountered during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The important role tires play in vehicles is increasingly being recognized. Tread Classification: Can be divided into ribbed tread, transverse tread tires, mixed tread tires, and off-road tread tires.
