I looked it up..since i'm running stretched tires on them..(215/35/19 19x9 and 235/35/19 19x10.5) they are smaller in diameter.. didn't know if there was a way for me to reset it to register these size? or am i stuck with that indicator forever....

 

I was told by the service mgr. where I purchased my '06 LS 430 that there was a new part that could replace the one on the car (somewhere on the ABS system) that would fix this problem. Since my tires are on 18" wheels I can't speak regarding your tires which you say are smaller than normal, regarding the overall diameter of the wheel. One thing for sure is that initializing is important when you reset using the button under the dash. Currently the red warning light is off on my instrument cluster but I expect it will go on again if I get into cold weather. Now my weather is warm in So. Calif. Hope this helps.

 

do you know what part # that is ? or if theres a specific name for it???

 

Sorry, but I don't know any more than I posted. I was told this by Brian, the service mgr at nort park Lexus In San Antonio , Texas.
