What are the hazards of replacing 165 tires with 175 tires?
3 Answers
Tire 165 can be replaced with 175, but the consequence is increased fuel consumption, and you also need to consider whether the tire will rub when turning the steering wheel to the limit. More relevant information is as follows: 1. Vehicles generally calculate mileage based on the number of rotations of the axle. After replacing tires, dynamic balancing is required to avoid wheel shaking and steering wheel vibration during driving. 2. In addition to the already occurring phenomenon of wheel shaking and steering wheel vibration, it is necessary to correct the balance of each edge part of the wheel by adding counterweights in a dynamic state. This correction process is what people commonly refer to as dynamic balancing, which is usually achieved by installing balance weights.
I recently helped my neighbor with tire issues, and there are quite a few risks when switching from 165 to 175. First, handling is affected—steering response slows, cornering stability decreases, and it's easier to skid in the rain, making the drive feel less stable. With the increased width, fuel consumption rises by about 10%, costing an extra few dozen dollars a month in gas. The dashboard also becomes inaccurate, with the speedometer reading lower, potentially leading to speeding tickets unnoticed. If the wheel well space is insufficient, the tires might rub against the fenders or suspension components, causing severe wear or even blowouts. Additionally, braking distance increases, doubling the danger during emergency stops. It's advisable to check the vehicle's manual or consult a professional technician for evaluation—don’t sacrifice safety for looks.
I usually pay attention to car maintenance, and changing to larger tires is no small matter. The change from 165 to 175 mainly poses risks in terms of economy and wear. Increased fuel consumption is inevitable; wider tires have greater resistance, costing at least a few hundred dollars more in fuel annually. Tire wear also accelerates, with the edges prone to excessive damage, reducing service life by 30%. Replacing tires more frequently is even less cost-effective. Handling performance suffers, with a vague sense of direction and increased body float at high speeds, significantly reducing comfort. If the wheel rims are not properly matched, the tires may loosen, affecting driving safety. It's best to stick with the original specifications to avoid additional costs and risks.
