Is the impact significant when changing from 245 tires to 265?

Not significant, it does not affect acceleration. Here are the detailed explanations: 1. Tire pressure: Maintain tire pressure between 2.4-2.5. Before driving each day, walk around the car to visually check for any loss of air pressure. It is best to equip a tire pressure monitoring system to help monitor real-time tire pressure. If the original vehicle is not equipped with one, purchase an internal or external version from the home shopping mall and install it. Inflate promptly if the tire pressure is too low. 2. Tire rotation: Tire rotation is also important. Rotate the tires as required at 20,000-40,000 kilometers, and perform a four-wheel alignment and dynamic balance check to effectively avoid excessive wear on any single tire. 3. Wear level: Pay attention to the wear level of the tire tread. Tires should be replaced at 40,000-60,000 kilometers, especially when the tread wear is only 2mm, replace them as soon as possible.
As a car modification enthusiast, I noticed significant changes after switching from 245 to 265 tires. The most obvious improvement is the enhanced grip, especially during high-speed cornering and rainy conditions—the car feels planted to the ground and less prone to slipping, giving me more confidence behind the wheel. The wider tires also give the car a much more aggressive, sporty look. However, there are downsides: fuel consumption increased by about 7-10%, with even higher costs for city driving—I calculated an extra 200-300 yuan per month on gas. Acceleration feels slower due to the heavier tires, robbing some of the thrill during takeoff. Road noise is noticeably louder, particularly at highway speeds. Another issue is wheel compatibility—265 tires may not fit directly on rims designed for 245s, so I had to upgrade to wider rims to avoid uneven wear and extend tire life. The speedometer might also be off, so I calibrated it to prevent speeding risks. Overall, if you're after performance, it's worth considering, but weigh the costs and daily practicality carefully.
