How do you correct computer for change in tire size?
I have a 2001 CL-S. I would like to change tire size from 215x50x17 to a tire size that will give me a greater number of tire choices / brands while not affecting the ABS and the electronic handling control which both depend on the tire and wheel size. Is there a way to adjust the cars computer to compensate for a change in tire size?

Try going with 235/45 or 225/45.

If you go into the diagnostic mode you can change a few things but you can also mess things up but its kinda cool having those settings. You press menu + map + cancel at the same time or you first press menu then map then cancel and hold them for 15-20 seconds. It will take you to the diagnostic mode... **caution** Dont change things around because some of the changes are permanent...

Is it self explanatory to back out without changing anything?

Interesting. While that is good to know, I have no idea why I would ever change any of those settings, except for tire calibration, which, by the way is (I believe) for satellite tracking purposes only, not for wheel size/speed calibration.
It is good to know that is there because now when I get my 18s I know to get my speedometer calibrated and my Navi.

I've been running 235/45's on stock 17's for 30k miles and my abs and vsa still work. True they are calibrated as a system for the 215/50 but since 235/45 is very close to stock diameter, there shouldnt be a problem. Also, tires vary slightly within the same size so to say it will get screwed up is a CYA exaggeration. That means going from Michelin to the same size Dunlop could "screw it up". Find another dealer.
