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

Changing from 245 tires to 265 has minimal impact and does not affect acceleration. Here are the specific details: 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 recommended to equip a tire pressure monitoring system to monitor real-time tire pressure. If the vehicle does not come 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. Tire rotation: Tire rotation is crucial. Rotate the tires as required every 20,000-40,000 kilometers, and perform a four-wheel alignment and dynamic balance check to effectively prevent excessive wear on any single tire. Wear level: Pay attention to the wear level of the tire tread. Tires should be replaced every 40,000-60,000 kilometers, especially when the tread wear is down to 2mm, replace them as soon as possible.
Upgrading from 245 to 265 tires has significant impacts. The most noticeable change is slower acceleration due to increased rolling resistance from wider tires – it feels like dragging extra weight when pressing the throttle. Fuel consumption inevitably rises; my friend reported an average increase of 0.8L/100km after the swap. On the upside, stability improves substantially with noticeably better high-speed cornering and superior wet-road grip. However, wheel width compatibility is critical – factory wheels that are too narrow for 265 tires may cause bulging, necessitating replacement with J-value-matched rims. Road noise also increases, particularly a pronounced hum on asphalt surfaces. I recommend first consulting your owner's manual for approved size ranges, as reckless modifications risk interference with suspension components.
