Taller Tires & Cruise Control

[Dark Sprite]

So it’s just when TC is off that your adaptive cruise isn’t working?

It’s either that or sport mode. I didn’t test that but can later possibly.
What a beautiful day in Chitown today!

Could it be the angle the car sits at affect the forward facing adaptive cruise sensor? Perhaps if the car remains at the same angle (or within 1-2 degrees) post wheel/tyre change everything is fine… can someone work out using agreywolfe’s before and after diameters if there would have been any change?

That's quite possible. I don't know what the precise angle change would be, but the changes for both the front and rear sizes are reasonably close. There shouldn't be a large change in the angle.

chiming in to complicate things more for yall: ive been running 20x10 fronts and 20x11 rears, 285/35 and 315/35 for over a year now upsized from my 19x9 and 19x9.5 255/40 and 275/40. roughly 1 inch larger all around, absolutely zero issues with cruise control, adaptive cruise, speed limiting, etc. your issues are probably electrical.

Glad you chimed in! The more examples of instances where problems occurred and did not occur the better. Electrical issues wouldn't explain why everything works normal again for @Ken H. when he puts his stock setup back on.

These two are nearly the same and don't have issues. Both coming from stock PP wheels. Maybe 20s aren't off the table for me after all.

I used the Steeda trident wheels and then went with different tires (but same sizes) than their packages. Used that as a guide. Michelin Pilot Sport 4 AS.

I have the EXACT same question, and have asked as well but most just reply that "they don't use cruise". I just bought 20" rims, but I'm waiting to hear what I can run and not have a problem. I was hoping to go 285/35 Fr, and 305/35 in the rear.

265 or 275 front would be ideal and a 305/30 rear.
