Are tires that have been driven for 30,000 miles or more generally more effective in inclement weather than new tires?

Answer: B — No, they are less effective

Tires that have been driven for 30,000 miles or more are generally less effective in inclement weather compared to new tires. Over time, tires accumulate wear and tear, which can significantly reduce their performance. The tread depth of tires is crucial for maintaining grip on slippery surfaces; as tires wear down, their ability to channel water away decreases, increasing the risk of hydroplaning on wet roads. Additionally, the rubber compounds used in tires can degrade, further affecting traction and handling. New tires typically have optimal tread depth and flexible rubber, which enhance grip in rain, snow, or icy conditions. Therefore, it is important for drivers to monitor tire wear and replace tires once they become worn to ensure maximum safety and performance in all weather conditions.
