#24 of 53 Re: frequent alignments? [msj09]
Aug 17, 2010 (9:06 am)
msj09 - i wondered if you did buy a 400H? Mine is a 2008 & at 20,000 miles the tires went down to the metal strips on the insides. A technician put new tires on & aligned them. He said after he aligned it that the alignment was good & should not have caused the premature tire wear & cupping on the insides . This seems to be a Lexus problem & not the tire mfg. I wonder if the weight of the hybrid battery has not been properly considered in the design & if the next set wears out quickly - that will confirm a Lexus problem for which I hope they will compensate. How many other people have this problem? Do we need to get legal representation? Jsea

I too had tire problems at 25000 miles, and this is after 4 years of babying this car. Look, this is a Lexus issue, that they won't take responsibility for, due to the exorbitant overall cost to them. I've been told by my service ppl, whom I trust, that this is a tire problem caused by excessive weight from the hybrid system which is unevenly distributed across the car, putting stress on the inside of the tires. Sounds reasonable enough to me. So, the "alignment" issue that one would normally expect from this kind of wear, really isn't the issue, and I doubt they can "overcorrect" the alignment to account for this. Hence, it will be a permanent problem with this vehicle IMHO. So, first I'd tel you to plan on buying tires about every 20,000 miles, which is ridiculous but unavoidable. It will take serious class action litigation to get Lexus attention, and these usually don't result in much change to consumers, it's the lawyers who get the money. I am VERY disappointed in this experience, and with the way Lexus is handling it....but maybe less surprised after seeing how Toyota the parent company, mishandled al of those recalls the past year. Lexus really blew a TON of consumer loyalty on this debacle.
I propose a realistic compromise to Lexus----charge the owner only $400 flat to replace the tires every 20000 miles, using the highest quality rated michelin tires, including balancing, alignment check, etc, for the remaining life of these cars. It's a cost I wasn't expecting and not thrilled about, but this is a high-price, high performance car, and I'd reasonably assume this cost as part of unforeseen "maintenance" for the 400h, if only Lexus would come clean on their end, and provide a reasonable "settlement" of this issue for everyone. If they did so, it would restore confidence in the brand, and as try could also plan on this as a maintenance item, they could negotiate cheaper pricing on the tires and still make a little money on the deal. For our part, at least we'd know we'd be getting new, high quality tires every 20k, at closer to cost, and any Lexus 400h owner should be able to afford this.
HOW ABOUT IT LEXUS.??

I have a Lexus 400H and had 4 new tires at approx 50,000 and was just told I need 4 more at 73,000. My service manager told me that I should expect to get 20,000 miles on the new tires. I just called Firestone and they warranty their Lexus 17" & 18" tires for 65,000 miles. Something does not add up here. We need to figure out what the heck is going on as I definitely think we should be getting more than 20,000 miles on new tires.

My tires looked OK from the outside & had plenty of tread left, but when they took them off the metal strips were showing & there was severe cupping. on the inside edge. I couldn't believe the deterioration at only 18,000 miles. I waited til 20,000 to take it in to Pep Boys & could have had a tire blow. I only took it in because of the noise, never saw the wear. Lexus needs to own up to this defect & reimburse people or they could be in for a class action suit from some hungry attorney. I'm really mad.

When some lawyer decides there is money to be made with the Lexus rx 400h tire wear issue, have hime contact me on this forum. I cannot in my right mind buy another lexus rx450h until this problem of tire wear is solved.
#29 of 53 Tire Wear Issue...

Is this by chance restricted to the F/awd versions of the RXh and HH..??
It is my understanding that these vehicles automatically apportion drive torque to the rear in a pre-emptive manner during low speed acceleration and turning.
In a more "standard" AWD or 4WD when the opposite drive is engaged the entire driveline and the tires are subjected to the stress and heat from driveline windup and/or tires scrubbing.
With the RXh and HH only the tire scrubbing is present when the opposite drive axles are engaged. That might well result in premature tread wear.
Go to the Highlander hybrid thread and search "tire wear".

I have 34K on 400H AWD. Original Good Year. The lexus dealer said needs replace soon, however Ok to drive 5000 ml more.
I also have 2008 lexus LX 570 - Michelin lattitude HP tires - 35000 miles on those. Dealer said I have to replace soon.
My Toyota Sienna 2002 had 65000 miles with firestone tires when I replaced them.
I can confirm : original tires from the factory run around 30K in average!
The tires from the stores are better for some reason and last longer!

Hope everyone LOOKS really well at their tires - on the inside rim. Mine looked fine outside & still had good tread left, on the inside they were down to the metal strapping & severly cupped. Only 17,000 miles old. I still think it's defective engineering. The test showed I didn't need alignment on the old tires, so what made them wear unevenly?? Cambre? Check them tires & be safe.

Regarding RX400h tire wear.
From all the issues you have all spoke about in reference to tire wear it comes down to "Under Inflated Tires". If you go to the goodyear home page and search for "recommened tire preasure" you will find the goodyear engineers won't take a stand. They say follow the OEM tire preasure on the door jab lable. On my 2008 it says 30psi. I know from years of messing with tires on water trucks, 5th wheel trailers, Chevrolets, Fords and motorcycles that if the side wall of the tire says 44 psi then I know that the tire manufacture has built that tire to withstand 44 psi with the determined pounds that tire will hold. So I determine the load "Weight" that will be on that peticular vehicle "Tire Load" and Adjust psi. So, in the case of the lexus they say 30 psi, goodyear on the sidewall of the 235/55r18 99v says 44 psi with a load range of "1700 lbs" each, then here is the "MATH"
1700lbs ea. x 4 = 6800 lbs total load these tires can handle, then the "Gross Vehicle Weight" (GVW) RX400h = 5520 lbs plus add the weight of 4 adults "800lbs" plus some bagage to get a total weight on all 4 tires to equal 6600 lbs then divide this by 4 = 1650 lbs per tire, Thus, I run my Lexus 400h tires at 40 psi and I have no tire issues. The stock tires have 16000 miles with normal tire wear with 60% tire tread left. Don't forget about the spare. My lexus monitors the tires which includes the spare. If you follow the above and you still have inside wear with standard rotation policies then you do have an alignment issue. Remember, an under inflated tire will wear on the outside/inside and an over inflated tire will wear in the middle. You must determine what works best for you and 30lbs of air preasure is not going to cut it.
