Process of Elimination IS250
Process of Elimination IS250
I am starting this thread in the hopes of finding out the cure for my IS250 which has been highlighted in my introduction thread. Most of you have suggested the tyres, so what I would like to know from current or ex IS25O users if they have or had used tyres that are not Dunlops and had no issues with them. I am currently using Dunlop sport maxx on the front and Dunlop SP01 at the rear.Any help or suggestions are most welcome. thank you
Hi All,

i cant offer any advice maybe tango or carpdiem could comment on this, have you contacted our trader WIM TOny of his staff could possibly offer advice on tyres
I was told by Lexus to stick with Dunlops and I have in order to cure the issues I am having. I have the sport maxx on the front and SP01 at the rear not sure if that could be the reason, so thats why I am trying to find out if anyone here using other than the Dunlops and are having no problems with it. Correct me if I am wrong but I think Tango had Bridgestones when he had his IS250.

My IS250 SE-L was delivered from the factory on Bridgestone Potenzas, but I did not like them as they were quite noisy. Within a year I put the 19" Rays VR rims on with wider Toyo's, and that's what the car has run on since. The car holds the road as well or better than my IS-F, and although it was lowered with stiffer springs the geometry was still set within Lexus specs by virtue of camber adjusters.

lebon So basically the gyres whatever you have does not affect much on the driving ie what I am experiencing at the moment. Do you reckon that what you have done to yours is the only way forward for me
From our previous discussions my best guess at the problem you describe was that you hadn't had the steering rack recall, or your car had sustained damage that had put your geometry out of the Lexus acceptable tolerances. Since then you have confirmed you have had a new steering rack, and your track rod end on one side has been replaced due to it being bent. You also stated that Lexus gave you inaccurate geometry reports, but WIM have since checked your geometry and confirmed they are within specification.
In theory your car should be driving as well as any other IS250 with a standard set-up, but you say it does not.
That leaves only aerodynamics, but as you haven't fitted any kind of extreme bodykit, that's got to be ruled out.
I guess I have to ask the obvious, and that is what tyre pressures are you running with?

lebon Tyre pressure at the front was 35 psi and the rear was 38psi but Tony did say he was going to reduce it by a pound or 2.
That should be OK. I'm running 38 psi on the IS-F, same as the 19" Toyos on the 250, but was running 36 all round on the 250 when it was on the 17" Bridgestones.
Without driving your car I haven't any more suggestions :confused1:.
