Will changing from 2254517 to 2255017 have any impact?

There will be impacts. The handling performance will slightly decrease, but the comfort will increase. At the same time, the speedometer will display inaccurately, and it will also affect the vehicle's annual inspection. Below is relevant information about tire modification: 1. Purpose: To improve the vehicle's high-speed performance and enhance its fashionable and aesthetic appearance. 2. Technical points: Under the same load conditions, wide-section tires have a smaller diameter compared to regular tires, lowering the wheel center and thus reducing the vehicle's center of gravity, which improves the car's handling stability. Therefore, they are widely used in high-speed cars. With the general improvement in power performance, the reduction in aspect ratio has become a major trend, usually accompanied by adjustments such as tire widening and wheel enlargement.
From a professional perspective, this tire replacement will indeed have impacts. Firstly, the tire diameter increases - the 2255017 has a sidewall height approximately 11mm taller than the original 2254517, resulting in larger overall tire diameter. This change will cause speedometer deviation, with actual speed being 3-5 km/h faster than displayed. Additionally, grip characteristics will change - the taller sidewalls mean more deformation during cornering, reducing crisp handling. Fuel consumption may slightly increase due to greater rotational inertia. You also need to verify sufficient wheel arch clearance to avoid rubbing inner liners at full lock. Finally, the instrument cluster may trigger warnings as the changed circumference requires ABS system recalibration. We recommend professional installation inspection rather than DIY replacement.
