Just went from stock tires on my 2016 wrangler to cooper discoverer s/t maxx 255/80/17 tires. Notice a small rumbling noise when I brake. Brakepads and rotors all in great shape, did not hear the noise before putting on new tires. Any ideas on what this may be caused by?

  • lug nuts torqued to spec with your torque wrench, not the tire shops?
    • you gonna tell us if it is coming from front or rear or which side?
  • Have you jacked one wheel up at a time & played with it to see if you can manually recreated the rumble?
  • Having someone in the driver seat applying brake as you turn it with your hand is useful.
  • is it when the brakes are engaging or when it is fully stopped?
  • have you hit the welcome Room to introduce yourself & your Jeep?

A rock or leftover lugnut in the dust shield?

I am a troll. Do not take my advice. It isn't going to help.

Are you certain you're not just feeling / hearing the lugs of your new tires?

Have you had mud tires before, and know what that sounds & feels like?

I got new rims and tires to replace my stock rims and tires,
This is coming from the front doesnt seem to be a specific side I only hear the noise when engaging brakes
I will try what you have suggested and I introduced myself in the welcome room sorry I am new to this site and didnt know about this until you mentioned it.

Thank you

Knobbier tires feel smoother at higher speeds because you're rolling over the mini peaks and valleys faster. When you brake, more weight is transferred to the front wheels and the steering is more loaded, so you'll feel more of the lugs. Also when slowing down, wind noise and other NVH (=noise, vibration, and harshness) are reduced so the tire NVH is more noticeable.

That being said, your noise description is a tad vague:

If not tire lugs, it could be ABS kicking in, wheel bearing failing, uncannily coincidental timing of digestive events, or maybe aliens . . .
