Traction Control System
Yesterday I put new tires on the front (only) and on the way home the Traction Control system went active while driving straight, on the freeway. I had to manually de-activate it from the button on the center console in order to keep the vehicle from stopping completly. I immeditalely associated the problem with the new tires, thinking they did something to one of the speed sensors. When I went back today I talked with a guy who "seemed" to know something about the car. He stated the problem lie in the fact that I now have two different types of tires on the car; one with a softer rubber compound (Treadwear rating of 150) vs a harder one with the new tires (Treadwear rating of 320). While I think he's not entirely accurate, and may be trying to sell me a second set of tires for the rear, I am wondering if mixing tires could be throwing the sensors off in some way (there was no indication anything was damaged upon removing and inspecting the wheels/hubs). Can anyone shed any light on this problem? THanks.

The (old) rear tire size is 295/35ZR18 and the (new) front tire size is 255/45ZR17

Tire height (not compound) is very important in keeping the TC system happy.
If your front tires are taller than the rears, this will happen every time.
Post your tire sizes, front and rear...It's a 99.9% safe bet that's where your problem is.
