Hello to all - Phil01 - 13-04-2019

I dont think it is tyre related really,
The poor guy has replaced all four with matching brands,
In the past I have driving with some mis-matched tyres and have never experienced severe probs like him.
Sounds like a suspension/tyre contact control eg damper/arb's or even alignment.

Phil01 Strange problem you have there, especially if it has been to WIM, as I am sure they would have found your problem.
These cars feel planted infact one of the best at high speed.
sounds like the obvious but is the front anti-roll bar fitted securely by the clamps/rubbers and the arb links have no play in them?
Are your dampers in good nick??
Lots to check, so can you please itemise what you have replaced/checked

WIM did not find anything wrong except the toe was slightly off. Items replaced were track rod end because they were bend the oxygen sensors, 4 brand new dunlops and finally steering rack because the steering felt very vague when driving but now the steering issue is solved and a full service done 2 weeks ago.

Sorry to ask but dont all Dunlops come with reinforced side walls as mine the fronts are dunlop sport maxx and the rears are dunlop sp 01

Yes it was great prior to 4 months ago. all this started when I found out my track rod end was bend.

OK, why was the TRE bent??

Phil01 OK, why was the TRE bent??

Lexus claims I had jack the car up wrongly which I did not or I have hit a pothole.

So the rear tyres are not reinforced sidewalls but a rayon cord reinforced not sure what that means


Hello to all - FirebirdPhil - 13-04-2019

Are the Sport Max not semi- run flats? and SP 01 normal? If so is there a difference between the front and back causing this issue?

i feel sure Sport Max can be run flat for a limited distance at low speed.
