I believe my situation is quite similar to yours, even though the tires are neither worn nor of low quality.

Hello Lexus Club members! I hope you're all doing well! I've had my Lexus UX250 for a few weeks now, and overall, I'm thrilled with it. However, there's one thing that has been on my mind. I've been noticing a low noise coming from what seems to be the front tires, especially when I'm driving at low speeds on flat surfaces like parking lots, and it becomes more noticeable when I'm making turns. My car is equipped with 18" Dunlop run-flat tires. I know that run-flat tires tend to be a bit noisier in general, but I'm not entirely convinced that the noise I'm hearing is solely due to that. It's peculiar because it seems to follow a rhythmic pattern, like a pulsating sound that comes and goes in a consistent cycle. I did take my car to Halfords for an inspection, and I also recently had a full service performed at a Lexus centre. Unfortunately, neither of them could identify any issues. One observation I made is that the front and rear tires have different tread depths. Could this variation in tread depth be contributing to the noise issue? Or do any of you have alternative ideas or suggestions regarding what might be causing this noise? Here are the tread depth measurements for reference: Off-side front tire: 4/3/4 Near-side front tire: 4/3/4 Near-side rear tire: 6/5.5/5.5 Off-side rear tire: 6/5.5/6 I'd greatly appreciate any insights or advice you might have. Thanks in advance!
