I had two new tyres recently at back and they cleaned the rims etc. due to the pressure prob.... made no difference at all, in my case, but all my wheels are badly corroded, I guess for me refurb is the only answer but for Nick5 who posted first, he may benefit from trying that.

I have one tyre in particular losing pressure a lot and am sure it is due to wheel corrosion. The only answer is to refurbish the wheels which is expensive on what is now an old car but I guess this is probably the problem for you too....most likely wheel corrosion... my lexus wheels started corroding much too early in their life!

I replaced my originals with bridgestones again, am totally pleased with them, and personally dont find them noisy, the inside of my lex is serenely quiet as it always was!! :winky:

Impossible to study and give you a real 100% wim reply but in reality the tyre sidewall is more than able to absorb traffic calming obstacles...The deflection is called 'slip angle' ... this is much more intrusive on a long high speed bend due to the additional centrifugal forces than any traffic calming obstacle. I do remember now that on my first lexus service the guy tried to imply that I had probably been over a lot of traffic bumps when he pointed out that my good looking tyres were in fact worn to baldness on the inside edge where you really could not see it with a general look. I rarely go over bumps so I guess that is a lexus excuse. I am surprised though that a car of this price has a general prob like this, after all tyres are expensive and you do not expect it on an expensive car.... someone at lexus obviously did not do their homework at the beginning. I must look at my second set as they look fine, but i will be really annoyed if they are bald on the inside edges. Also my second set of alloys are corroding worse than the originals did, again this is not what you expect on a car of this price. I must say WIM your website looks good - I wonder why lexus made such a bad mistake if the geo probs are down to them.

Nothing wrong being obsessed with saving money and possibly your life.... As MacRS200 said Lexus did get it wrong Geometrically...not by much but nevertheless wrong. The wim set-up has proved successful...every car that comes to me has a problem hence the appointment and every car re-positioned has been fine thereafter, those positions i have made public so i am not trying to capture the recovery market only the awareness market. The situation with rhoseigr's car is indeed unusual but now he has an image of the geometry any future wear can be 'fine-tuned out' this practice is necessary since we are all unique so the positions can only represent a suggestion. I must say, i was astonished to see that my tyres wore so badly, I did not even realise because if was the inner edges which you just dont see at all easily, they told me on my first service and i had not driven millions of miles etc. The only point i was trying to make was that the guy starting this post went to drury lane diagnostics, who he felt knew what they were talking about, and they told him his geo was within suitable limits........ yet he was there because of this adverse wear, which seems to show that it is not necessarily, or only, caused by wrong geometry. From what I have read here, it is a common prob with lexus. I take on board what you say here about wrong set up by lexus. I have not done anything about mine, as i did not really know what could be done, but my second set of tyres have not gone the same way.... mind you i will try to have a really good look at the inside edges tomorrow.....

your message has proved what I have always believed... you lot are obsessed with geometry checks as the be all and end all, and this just shows that you need to realise this tyre wear is a basic design fault to put it in a nutshell. my tyres has gone the same way from brand new on a brand new car - and your post has proved that it still happens with correct goemetry!! face it lads it is one of the (very few) downsides of owning a lexus!! :winky:

Hope that sausage was worth it..?

Yes, the salt is the cause, Japan so much warmer dont need salt in the winter, but do remember Mr. Frosty, that my replacement wheels are only a year on my car and they are corroding more than the originals actually. I am not a motorway driver etc. and keep the wheels clean, so it just shows you the extent of the problem with the salt. But as I say, even replacement wheels do not solve the problem at the end of the day...... it all happens again...

yes, I had my wheels changed under warranty a year ago, all five no problem, but the bad news is that a year later they are starting to corrode again, after being well looked after and cleaned regularly to avoid salt. Car now out of warranty, have not yet approached them, but dont expect much joy, and take a poor view of this on a car of this price. Not high mileage, not much motorway use, it is unacceptable. also the replacements were not as attractive as my originals which had some frosting on the spokes, replacements were all polished the same. But of course the main problem is.... the problem is still there.... and the car is not four years old yet. Has not happened on my husband's honda.... why can't lexus sort it?? :duh:

I always use bridgestones on my is sport, as the originals, and had been very happy with them, apart from the fact that the originals wore very unevenly, but that was not obviously a tyre problem... in your case you probably do not know the past history of your tyres as you have only just purchased your car, so who knows .... they may have been over inflated etc. in the past....and you just dont know how it was driven probably.... so the problem may not actually be the quality of the tyres. good luck anyway with that. :winky:

Oh goodness! some of the questions on here make me wonder about you lot..... How long is a piece of string??? take the tyre to a tyre place and they will advise you - surely that is the obvious sensible thing to do, cannot inspect a cut tyre properly over the internet. Also you did not originally say it was a merc tyre, it was assumed you were talking about your lexus tyre. Cannot expect anyone on here to know the thickness of a merc tyre sidewall, or to comment safely on whether you should change it.... I am confused at these banal questions sometimes...... :o

they are not having a laugh... they are taking you for a ride. Yes, I replaced my original tyres which wore completely on the inside edge but not the outside, so i did not immediately notice...I got bridgestones again from a place in Kent for about £120 each tyre, - same as originals. Mind you roadkill, how have you worn tyres AND the spare down so much - even to 5mm - on what you say... perhaps you have got the same uneven wear as I had which of course makes them illegal, my inside edges were bald but was not at all obvious. My husband has a civic type R, and he wa quotted some crazy price by the Honda agent for his new ones - I guess that it always the way at the main dealership. I must say, slightly off subject, but I was also really upset that my lexus service costs almost twice as much as his honda type R service.... i keep meaning to ask them why...

you wont go wrong with just washing with autoglym, the best car shampoo. Main thing is to wash wheels regularly... :winky: dont let the brake dust stay too long on them. :winky:

well lyford, you are getting much the same advice from everyone. Brake dust is obviously not the problem, I am definitely not heavy on the brakes and mine went the same way from new - no it is definitely the lacquer which does not resist salt. I have a link with Japan in that my son has been working in tokyo for two years now and he tells me they do not put salt on their roads in the winter and the original lacquer used does not withstand the tons of salt put on our roads in the UK. . it is as simple as that. My replacements have been fine for a year now, but do just wash them over regularly, just the wheels, I am sure this helps and of course removes the salt reasonably quickly from them. Mine are still good... so good luck!

that is odd, as I have my wheels changed for the same reason and the replacement set were finished in a different way which should help avoid the problem again. You will see that the surface finish is different to your original wheel (polished on all surfaces, not partly frosted as original IS wheels).. I must say I do not think the replacements look so attractive..... However, all I would advise you is to keep the wheels clean as far as possible. The salt in winter attacks them and giving them a wash over regularly, especially in winter to remove the salt. even when not washing the whole car, will help the problem andi well worth it. My second set are fine. I don't know whether your dealer with replace them again.... but at least keeping them clean from salt will definitely help. :winky:
