I own a 350Z and I just recently put new tires on the front and back. My back tires are wider than the front. They look great but unfortunately when I go through a turn, the traction control turns on. I know that I'm not sliding and there is no need for it to come on.

Does anyone know how to fix this without turning off the traction control? I have called around and no one seems to know for sure. Not even the tire place that I purchased them from. I did read somewhere that I might need to have the same width in the front and back.

The tires that I put on are 225/45/18 YR and 265/35/18 YR Toyo T1R. Also, these are on the stock 06 wheels.
Any ideas?
