I had a thumping start yesterday morning sounding like a flat tire. Pulled over all air pressures are fine. Got up to about 70-80 and it went away. Slow back down it’s not there. Once I come to a stop for about 3-5 minutes it’s back. Going slow it is very slight thumping but once its like a flat tire sound it doesn’t go away until I go fast. Seems to get faster with speed. I don’t feel it in the steering wheel. Rear tires are about 3 weeks old. Front tires balanced with a front end alignment. 08 IS350

I’ll be under for an oil change today. But the rear view mirror shakes and you can feel it in the seat slightly.

While I was changing the oil I checked the front tires. Found this crack in the left and I checked the true of them and the right tire isn’t true.
Going to the tire shop tomorrow for 2 new tires
TPMS don’t work so I’ll get 4 new ones while I’m there.
Hope this fixes it.

Had new tires put on the front and all 4 TPMS sensors.
Thumping still there. Started driving hard and noticed it got louder when I hit the brakes hard.
Replaced right rear caliper, rotor and pads.
Noise seems to be gone. I’ve never had a noise like this from brakes in my life.
But it sure is nice not to have the low air light on.

Rim has a slight bend to it. I’m probably going to be getting summer rims and tires soon.
Ive never had a vibration like that from a sticky caliper.
