I recently put on 19" all the way around my '05 Z Enthusiast. On several occasions in a turn the slip light will come on for no appearent reason. Has anyone else had this issue? Tire sizes are Front 235/35z/r19 rears 265/30z/r19

 

what are your tire sizes?

 

tire size affects the tcs
not rim size.

 

the height of your wheel and tire combo has to be higher in the rear then your front. with your tire setup, your fronts are taller thus causing vdc to get confused since the rears are spinning faster then your fronts which is what vdc tries to correct.

 

+1

 

change front to back.

 

Ditto on the wrong tire sizes

Fronts height - 25.48"
Rear height - 25.26"

If you bought the wheels/tires through any competent shop they should have caught this and should correct it.

 

I am going to be the lone dissenter on this one. The enthusiast has TCS. TCS is not sensitive to tire size.

 

I'll pitch in with you on that one Davidv.

When you "recently put on 19" all the way around", you're driving on slippery tires (demolding agent is still on the thread). It's easier to spin them.

Lower profile also makes for less compliance, again, easier to break traction and spin...

 

Your dissent is noted but it's wrong. From the FSM:

TCS Function

The wheel spin occurrence of the drive wheels is detected by the ABS actuator and electric unit (control unit) using the wheel speed signals from all four wheels, so when wheel spin occurs, the amount of wheel spin is reduced by controlling the hydraulic brakes on the right and left rear wheels, cutting the fuel to the engine, and partially closing the throttle valve to reduce the engine torque. The throttle opening is also controlled to obtain the optimum engine torque.

Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the optimum traction has the highest priority under TCS operation.

TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a road with a varying surface friction coefficient.

During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.

TCS, like VDC both work by monitoring the wheel speeds sensors from all four wheels. The computer is programmed to expect a certain stagger ratio resulting in different front to rear wheels speeds. If you don't put the right sized tires on, you're going to trip VDC or TCS.

 

I stand corrected. Excuse me while I take my foot out of my mouth.

 

Every company's tire size varies even though its the same..I have 235/35/19, and 265/30/19 and the back diamete is probably about 1/2in taller..I couldn't tell you why but the sizes are right on the tires.

BFG KDW2 by the way.. I get the TCS light too but Im guessing its just camber

 

 

lol camber? wishfull thinking, its the wrong size tires buddy, plus i feel terrible for your wheels, you have virtually no protection. better double and triple check for pot holes, your wheels dont have a prayer, forged or not.
