45 tires are not considered thin. Below is relevant information about 45 aspect ratio tires: 1. Professionals explain that tires with an aspect ratio generally below 45% are referred to as "thin tires"; 2. The so-called aspect ratio refers to the ratio of the tire's natural thickness to its width; 3. For wheels of a certain width, the lower the aspect ratio, the thinner the tire section; 4. Thicker tires are more prone to distortion. On high-quality road surfaces, if the aspect ratio is low and the sidewall is short, the tire is less likely to distort, allowing for more effective support, thereby providing greater traction and achieving more responsive handling. However, tires must have a certain thickness to isolate the wheel rim from the road surface. On rough and poor roads, tires with very low aspect ratios struggle to provide adequate cushioning.

I've been driving for over a decade and have used tires with various aspect ratios. My previous car had 45-series tires, which indeed provided precise handling during high-speed cornering and strong grip, making it feel particularly sporty. However, thin tires also come with obvious drawbacks, such as loud road noise, poor cushioning, and a harsh ride over speed bumps or potholes, often causing discomfort from the jolting. Over time, they may also develop bulges, especially in areas with many potholes, requiring frequent tire pressure checks to avoid blowout risks. So, 45 isn't absolutely too thin—it suits performance-oriented sports cars or young drivers who frequently drive in the city. But for seasoned drivers like me who are used to long-distance driving, it might be too taxing. I'd recommend considering a higher aspect ratio, like 55, to balance comfort.

As an enthusiastic driver, I don't consider 45 aspect ratio tires thin at all. They make the car respond faster and provide agile handling in corners. When I drive hot hatches, I always choose this type of tire because it gives me a direct connection with the road. While low-profile tires enhance handling performance, they sacrifice daily comfort with poorer shock absorption. They can be noisy on gravel roads and are more prone to punctures from nails due to their thinner sidewalls. But it all depends on the purpose - 45 ratio tires perform fine on straight highways or urban roads. The key is to match them with your driving habits and vehicle type, not blindly follow the trend of ultra-low-profile tires.

I've encountered many issues while repairing cars. A 45 aspect ratio tire isn't the thinnest, but its relatively low sidewall thickness results in weaker shock absorption, leading to uncomfortable rides. It's also more prone to rim damage or bulges from road obstacles or low-speed impacts, increasing repair costs. I recommend frequently checking tire pressure and road condition adaptability to ensure safe driving and avoid accidents.

Thinking back to when I first started driving, tires generally had higher aspect ratios. Nowadays, tires with smaller numbers like 45 are popular, offering better handling and quicker response. However, I've noticed a significant drop in comfort, especially when carrying family members—the ride is much bumpier and noisier. There's a need to balance performance and practicality. While 45 isn't extremely low-profile, it's more suited for sports models.

From a family car perspective, a 45 aspect ratio tire is indeed too thin. The thin sidewalls result in poor cushioning, making the ride bumpy and noisy for children, and increasing the risk of wheel damage. It is recommended to choose a 60 or 65 aspect ratio for better safety and comfort, as it can handle daily road conditions more effectively.
