Water in tires causing vibration

Recommended Posts

I have a 2015 RX350 F Sport (This is our second RX we bought from the same dealer, no issues with the first RX) we bought with 19K miles on it. Great car with no issues except for this vibration issue that showed up around 30K. Noticed a slight vibration in the rear like a tire out of balance so when we went for 30K service I had them check tire balance. What they found after trying to balance one of the tire was a small amount of water inside the tire. (Note: I had fixed a leak in that tire and had added air from my compressor so we assumed it came from my compressor)

No problems until about 34K noticed a vibration on the front end like a tire out of balance. I had not done anything to any of the tires (no air added). So we went for our 35K service. They checked my vibration issue and after numerous attempts to balance they broke down all four tires and found small amount of water in each tire. With one tire having more than the others causing my issue.

Couple of their mechanics said they have seen this happen a few times before on the RX but I have searched around on google and not finding any posts about an issue like this. Back when I was young in the 70's I worked on cars for a living, never in my life saw a tire make water internally on its on no matter the condition. Water in tires has happened but usually we were able to determine which service center had water in their air.

Service guy told me this is not covered under warranty, not sure I agree since we have only put air in the one tire since we have owned it, they have done all the work on the car. I think they must have a moisture issue in their air system. I asked if they had nitrogen but they do not. So, I think I will have them filled with nitrogen and hopefully eliminate future problems.

I wanted to ask you guys on the forum if anyone ever had this problem or heard about this type of problem. Any past experience or comments you may have would be appreciated

Thanks in advance

Hi Kenny

I have never encountered water naturally occurring in tyres without introducing it somehow.

Water in the compressor, if it hasn't been drained down, is the only possible reason.

Maybe Nitrogen is the way forward in this situation

Let us know how it all goes

Update on water in tires on RX 350. I have been back to dealership, they cleaned out water and balanced, few weeks later vibration was back so I took it upon myself to get another opinion. Went to my favorite local tire shop, had them dismount all four tires, sure enough water in every tire. Approximately 2 ounces in one, 4 ounces in another then the last two had a good 6-8 ounces in each one. So we cleaned everything up, rebalanced and filled with nitrogen this time. Went on a 10 day vacation driving through rain and such vibration has returned. Took back to the dealership today, they removed tires from rims and found water in them again. The service manager said he called Lexus and talked to the person that goes from store to store and apparently I am not alone in my struggle. According to the manager Lexus has been investigating this issues but it has only occurred on 2015 RX350 F Sport with Dunlop tires. He says Lexus has determined it is a tire problem and not a warranty issue. I disagree since they decided which tires to put on the car from the factory but no luck getting them to do anything about it. They have 38,000 miles with a good 10-15000 miles left on the tread. I posted this in case someone else has this really odd occurrence to let them know they are not crazy. It can and did happen.

I plan to contact Dunlop but really don't expect they will do anything for me. Wish me luck

I just received a call from my dealership telling me that they found water in my tires.  Dealership rep says he has never seen or heard of anything like this.  How in the world did this happen?  RX 450h 32k miles.

Apparently a lot of compressors don't have a water filter on the air outlet.  Nitrogen wont help, as air is already 80% nitrogen.  Poor equipment maintenance is the fault.

RX4502015 - would you mind telling me what type of wheels your vehicle has on it? Mine has the dark gray/black alloy wheels. Just wondering if there are similarities.

My dealership is now saying they have had two other customers with my same issue. This is a really busy dealership so I am sure water in the air lines is not their issue (even though logically this would be the place to look). I personally went to a local tire shop, watched them remove the water from my wheels and fill with nitrogen before we left on vacation. Drove around 1500 miles only experienced mild vibrations in the rear on the way home. Took it back to the dealer, they removed the tires from the rims and found 24 ounces of water in the tire. No real good explanation other than they are investigating. But I know there was no air added to these tires after they were cleaned out and nitrogen installed. 

Dealer got Lexus to agree to pay for two ties and I paid for two. They installed Michelin Latitude this time. They said the only common denominator was the Dunlop tires, I told them when I left that we will see and that if water shows up in these tires, the only thing left is the alloy wheels (in my opinion I feel this is what the problem is) Does not make any sense that water could get in the tires and air not get out, however temperature change on the alloy wheels (heat up when applying brakes then quickly cooling off) could possibly create moisture. Most of our driving is 20 miles each way to Lexington Ky several times a week otherwise just here in town driving

Please let other know that if this happens to them it is not as crazy as it sounds. I have worked on cars most of my life and have never heard of or experienced this type of issue. Naturally the dealer thought I was just wacky saying the tires were getting water in them all by themselves but as it turned out I was just their first customer to complain about it. I was informed this morning that  another customer (32K (miles) came in with a car like mine but had not complained about vibration, they checked his wheels for water out of curiosity and guess what he had water in his tires. So as crazy as this sounds it can and did happen

Now we wait as we put some miles on these tires to see if it happens again. Will update later on

Would you care to tell me if your car has Dunlop tires? Also what type of rims does it have on it? Car is 2015 RX350 with 38K miles,wheels are spoked grey/black alloy wheels with Dunlop tires. Lexus is saying it is a tire problem but I can't find anyone that agrees with them that water is getting in the tire from outside. I have been arguing with them since 25K service when they found water in a tire. Now they have changed their tune and have two other customers show up at my dealer with same issue. They agreed to buy me two new tires so we replaced them all Appreciate any help

      Hello,
      I have bought a new 2016 RX350 and the vehicle was driven 30k. When i took my car for servicing, the dealer has mentioned "BG fuel and oil additive" and "replace gear oil within rear differential and transfer case" which the dealer said was recommended by Lexus. Is it really necessary to perform these services? How does it affect my vehicle? If these options needs to performed then can i delay for another 5 or 10k?
      And if i have to opt in for these services then can you please suggest any mechanic outside of Lexus dealer as the dealer costs are 283 for parts and 478 for labor. These prices includes other services which i have not mentioned here. When i opted out of these two, the price was reduced by over $300.
      Any information shared is greatly appreciated.

      My guess would be either the first gen rx300 or the most recent gen rx350 because they have the most ground clearance. Not sure how they all compare with locking diffs, gearing, wheel articulation, low end torque, etc since I only own the first gen. 
      Second question: is the RX a lot worse off road than the LX and GX or are they close?

      Hi, I am new to the forum and have a question on my 2009 RX350: Can I use a weight distribution hitch on this vehicle to pull a 2000 lbs (dry weight) camper trailer from southern Ontario to the Rockies and back? Or would the torsion from this type of hitch bend the frame or snap the bolts? The purpose of the slightly stronger weight distrib hitch (4000 lbs vs 3500 for my existing hitch) would be to level the Lexus, reduce trailer bounce on bumps, and reduce trailer sway.
      Has anyone used a weight distribution hitch on their 2009 or older RX without problems? The available Curt #13530 weight distrib hitch (rated to tow up to 4000 lbs with weight distribution) is explicitly stated by Curt to fit the 2009 RX350 (among other models and years), but I can't find a statement anywhere that it can be used as a weight distribution hitch on the 2009 or older RX350 instead of just as a regular hitch. 
      My situation is this:
      - The trailer GVWR is 3500 lbs (unloaded weight is only 2000 lbs).
      - The trailer's dry tongue weight (hitch weight) is about 220 lbs.
      - The current hitch receiver installed on the vehicle is a factory model typically installed by a Lexus or Toyota dealer. 
      - The installed factory hitch as far as I know is NOT rated for use with weight distribution bars (torsion bars). The sticker on the hitch only mentions the regular towing limit of 3500 pounds and does not mention a weight distribution towing limit.
      - A local hitch installation expert believes the frame of the RX350 probably was not designed to accommodate a weight distribution hitch until 2010. Our RX350 is a 2009. The local expert, who looked at our existing hitch on a hoist, believes we won't gain enough by replacing the hitch.
      - The vehicle as it is now is rated to tow 3500 lbs with the factory tow package which I have, and rated for a max tongue weight of 350 lbs.
      - But the trailer currently does sway and bounce some when we tow it. And the Lexus sags several inches in the back. I know the sway can be corrected by an antisway bar and probably be improved by raising the ball mount on the vehicle, which is currently about 2 inches too low for the trailer.
      -  The after-market Curt #13530 weight distrib hitch mentioned above (rated to tow up to 4000 lbs with weight distribution) is attached to the frame by 6 bolts rather than the 4 bolts that I think are used for the current factory hitch. The threads on the frame are cage nuts (captured nuts or maybe they are welded on, not sure)
      So to sum up, I would like to know:
      - Can a weight distribution hitch be used on the 2009 RX350 without bending the frame or breaking the bolts holding the hitch to the frame
      - Does the fact that Curt designates its weight distribution hitch as fitting my vehicle mean that it is intended to be used as a weight distribution hitch on my vehicle, or just as a regular hitch?
      - For a trailer that may weigh 2,800 lbs loaded, is it overkill to replace my perfectly functional non-weight distribution hitch with a weight distribution hitch that adds 500 lbs of towing capacity and 50 lbs of tongue weight capacity. The cost of the new Curt hitch would be about $ 240 Canadian to me, plus maybe $30 for a torque wrench to install the hitch myself.
      Thank you in advance for some expert advice on these questions.

      Does any one know what on earth this button is for?

      I have had the CEL and VSC lights come up a few times on my Wife's RX350 a few times. The first time I took it to the stealer, and they charged me $80 to clear it and tell me that it wasn't covered under engine warranty, and sometimes they just pop up for no reason.
      So this time I used a reader ( available for $80 ) and read code P0354, Ign coil D. With a little googling, I found that D is the front center coil.
      Ordered coil online for $45.
      Now the best part, the how to:
      1) Pop hood and remove engine cover. You simply grab on to it and pull it up. It just pops off.
      2) Remove new part from box, so you know what you're looking for.
      3) Locate problem coil.
      4) Use 10mm socket to remove the only bolt on the coil.
      5) remove wiring connection.
      6) replace with new part.
