I put some 16 inch RSX rims on my car and ever since I put them on my ATTS light comes on every couple of miles. Currently I have the RSX rims in the front and some after market 17's in the back because I'm painting the other two. Also I noticed that it looks like the RSX rims are touching my calipers even though I don't hear any noises. Any suggestions to how I can fix this?

SH DRIVER

The ATTS mod monitor is monitoring the wheel speed of all four wheels.
The same 4 wheel sensors are feeding the same data to the ABS unit.
Your going to have to make all 4 wheels the same diameter or the light will stay on and most likely the ATTS unit ,and possibly the ABS unit, will remain in a disabled state for your safety.

Either grind down the caliper slightly or get wheel spacers for your clearance issue.

And like SH DRIVER says, the ATTS reads wheel speed and compares it to the supposed speed (speedometer) the car is traveling and determines the diameter of the tires. The ones you put on the rear are causing the ATTS unit to trip and it will stay that way until you put the RSX rims back on.

I also have RSX rims on my SH but the light doesn't come on because the tires I have are the same diameter that the stock ones are.

Can I disable the ATTS while I get all the tires the same diameter? The reason I ask is because I still need to drive the car for work and I don't want to break the ATTS.

You can remove the fuse for the ATTS unit in the under-dash panel. Otherwise the ATTS unit will handle itself and either compensate for the problems or disable itself when it needs to.
