Hello,

my 2024 RX350h have 8000 KM, Normally, I drive less in winter time. We have already rotated the tires, front with rear and I am noticing the vibration as I reach 120KM or above. The tires have 7mm threading left.

today I visited Costco and lowered the tire pressure from 36PSI to 33PSI.

 

Question was: Did that change the symptom AT ALL? If you could detect any difference, it might be tires.

A severe pothole could damage both tires on one side. BTDT.

+++++++++++++

If your RX is under warranty, could you ask your dealer if you could test-drive a different RX? If that one is OK, you may have proved something....


Are the tires wearing EVENLY? Measure with a depth gauge, or ask a tire store to show you their measurement.

36 versus 33 should not make a difference. We run our RX's 21 inch tires at 38 F 34 R. Spec is 33 F 33 R.


120KPH is a typical beginning speed for balance or out-of-round issues to be noticeable.

If you are sensitive to steering, you might sense a defective (broken belt) tire at parking speeds.


Good luck!

 

I have aftermarket rims with Pirellis. I don’t trust anyone touching my vehicle :-) But I bought and mounted these wheels through a dealer network that does nothing but rims, tires, and sensors. All perfect. But I’m telling you, I feel you! Stick with it, don’t give up, and never think you’re being too picky!

I have even tire thread depth of 7mm, they are like brand new tires. I purchased my RX350h Lexus back in August of 2024. I drove less on freeways. It is a co-incidence when I drove at 130 KM on Interstate 400, I felt steering wheel vibration.

To my knowledge, both Lexus dealerships (Erin Park and Don Valley North Lexus) claim they went through extensive checkup and re-done road force balancing. I can still feel vibration at 120 or above KM.

Do you believe I should speak to Michelin and see they will honor me the replacement tires.

I have purchased ECP with my Lexus and the car is under warranty.

As per prior conversation with both Lexus dealerships, they will not test drive RX above 100KM. It is as per the state law.

To my knowledge, they will not run road force for over 100 KM for balancing the tires.

 

^^^ sad.

Perhaps, have your tires balanced at a performance shop. I know of a couple around here that prep cars for racetracks...with NO speed limits.

Wouldn't hurt to ASK Michelin....

 

Thanks for your response. This morning I drove from Ottawa to Toronto, I noticed where the road conditions are not that great, I felt some vibration in my steering wheel and in other areas, ride is decent.
I am of the opinion that Don Valley North Lexus have fixed the vibration for Upto 120 to 125 KM, but not above that speed.

 

Do you recall which performance shop you have visited to get your tires re balanced. Please advise,
