Does changing from 18-inch to 19-inch rims have any impact?
3 Answers
Changing from 18-inch to 19-inch rims may reduce the comfort of the vehicle and even cause wear and tear. Below is a detailed introduction about car rims: 1. Overview: The rim (Car-Rim) is the central part of the wheel where the axle is installed, also known as the "wheel rim" or "steel rim." Rims are prone to accumulating dirt, and if not cleaned for a long time, they may corrode or deform, posing safety hazards. 2. Classification: Rims can be divided into steel rims and alloy rims based on material, each with its own advantages and disadvantages. The main advantage of steel rims is their simple manufacturing process (usually produced through casting, whereas aluminum alloy rims are typically made using low-pressure casting), relatively low cost, and strong resistance to metal fatigue.
After upgrading to 19-inch wheels, the car's handling has noticeably improved—corners feel more stable, and steering is more precise, making it ideal for driving enthusiasts. However, acceleration has clearly slowed down because the larger wheels add weight, requiring the engine to work harder to push them, resulting in slower response at low speeds. Ride comfort has also suffered, with bumps and road imperfections feeling harsher, increasing seat vibrations and making long drives more tiring. Fuel consumption has risen by about 10% on average, and tire wear is faster, with thinner sidewalls making them more prone to damage. It's crucial to ensure the new wheels and tires are properly matched in size; otherwise, the speedometer readings may be inaccurate. It's recommended to have a professional inspect the suspension system—don’t just focus on aesthetics.
Safety is a major concern when upgrading to larger wheels. The increased wheel size reduces ground clearance, making the ride bumpier on uneven roads and increasing the risk of losing control or wheel deformation. Braking performance may also be affected, with a slight increase in stopping distance, especially on wet surfaces. Switching to 19-inch tires means wider and thinner treads, which improves grip but reduces stability on rough roads or at high speeds—new drivers should be particularly cautious. Always opt for high-quality tires; cheap, off-brand tires significantly raise the risk of blowouts. Cost-wise, insurance adjustments may be needed, and larger wheels increase fuel consumption. Regularly monitor tire pressure for optimal performance.
