What are the effects of changing to 205 wide tires on a Jetta?

It helps improve stability at medium and high speeds, but there are also side effects caused by increased resistance. Advantages of improving stability at medium and high speeds: Wider tires will make the car look more dynamic and improve its appearance, while also enhancing handling stability. With the same tire diameter, increasing the tread width helps expand the contact patch, making driving more stable and increasing grip, which is beneficial for improving stability at medium and high speeds. At the same time, it can directly enhance the performance of the braking system and shorten braking distance. Disadvantages: Fuel consumption will increase. This is mainly due to the side effect of increased resistance. Comfort decreases. Since the sidewalls are relatively narrower and rigidity increases, ride comfort will be somewhat reduced. Additionally, steering becomes heavier, and high-speed noise also increases.
After switching to 205 wide tires on my old Jetta, the most noticeable improvement is the enhanced grip. I no longer feel nervous when taking turns, and it feels much more secure even when the road is wet during light rain. However, the increased rolling resistance from the wider tires is quite real. Previously, 200 yuan worth of gas could get me nearly 500 kilometers, but now it's just over 400. Acceleration has also become a bit sluggish, requiring deeper throttle input than before. Additionally, the noise from these tires is quite prominent—I have to turn up the music on the highway to drown out the tire roar. One more thing: don’t just focus on looks. Before changing tires, make sure to measure the wheel arch clearance. Once, when fully loaded, I hit a pothole and scraped the fender—there’s still a mark on the rear wheel to prove it.
After switching to 205 tires, the car sticks to the road like it has magnets, taking 60 mph curves on highway ramps without any drift. It feels especially secure driving on highways in the rain. But I must remind everyone, fuel consumption is unforgiving—my daily 50 km commute used to cost 800 yuan per month in gas, but now it's around 950. Wider tires also make the steering wheel heavier, making it quite a workout to reverse in narrow neighborhood roads. Personally, I think the original 195 tires, though they look thinner, are more worry-free for city driving. Additionally, with wider tires and more contact points, remember to rotate the front and rear tires every two months, or they'll wear out quickly.
