I am a proud new owner of a Chevy HHR LT. My question is, can I put larger tires on the rear to make my car look like a Hot Wheel?

I have heard that mixing the tires will cause the tire pressure sensors to go crazy.

Thanks for your help.

I would worry more about your ABS if you have it. Different readings frm the wheel speed sensors due to different size tire will likely turn on the ABS light and then your ABS will be inop.

 

It could void your warranty. GM is funny that way.
