I am going to be getting Z06 18" Chrome wheels all around and am not planning on putting the tire pressure sensors back on. Does anyone know if I am going to have error/warning messages on the DIC going off everytime I start the car b/c of lack of sensors on new wheels??

 

Why not reuse the sensors?
Yes, you will get error messages every time you start the car. Find someone with a Tech 2 programmer, and you can program the sensors out of the car's computer to not get any error messages.

To add to that your car must be a 2001 or later to program out the sensors.

 

Thanks for the feedback. Do you know if the Z06 replicas will accept the wheel sensors

 

They should take the sensors, but check with whomever you are getting the wheels from. Replace the rubber o-rings (cheap) as a matter of good practice.

These guys are right. Your car is too old to turn the sensors off.

The other thing that can give you DIC errors is if you screw up active handling by changing the outside diameter of the tire. For your car, the stock outside diameter is 25.6" F and 26.6" Rear. If you stay close to the stock diameter you can avoid headaches. Remember, it is not the diameter of the wheel that matters, it is the diameter of the wheel with the tire installed that you pick out.

Also note that changing the rear diameter will throw your speedometer accuracy off in a C5. :cheers:

 

You'll also have problems with the tire pressure sensors if your tires are over inflated. You'll get a high pressure message on the DIC if the pressure is 42+ psi. The only way you can get rid of it is to lower the pressure.

 

I think I'm even more confused now. Let me tell you guys what I want to do and maybe you can give me suggestions. I plan on taking the back tires 275/40/18 and using them for the front. I plan on buying two new tires for the rear wheels 295/35/18. Do you think that this will work and if not give me suggestions on what will. I do want all 18's all around and do want to widen the tire on the back b/c the car doesn't catch traction to well. Let me know what you guys would do. Any help is great b/c I do want to switch the wheels out and go wider on the back but I don't want error messages going off every time I get in the car. Thanks again.

 

:eek: Probably a bad move if you have active handling enabled. This is what you are proposing:

275/40/18F = 26.6" O.D.
295/35/18R = 26.1" O.D.

You are proposing bigger (O.D.) tires in the front than the rear.

These are two rules of thumb that you might find helpful:

1. Stay as close to stock O.D. as practical F & R.
2. Keep O.D. of front about 1" smaller than O.D. of rear to avoid active handling issues.

These are the sizes of 2 possibilities for the front if you want 18's up front:

265/35/18 = 25.3"
275/35/18 = 25.5"

If you want to buy two tires, leave the rears on and go with the 275's in the front. You will wind up with sizes nearly identical to stock.

If you want to buy four tires and put 295's on the rear, go with 265's in the front. The 295 rears are slightly smaller than non-Z06 stock and the 265 fronts will help you maintain the diameter separation front to rear. Your speedometer will not be too far off - about 1 mph at normal highway speeds.

Not all tire manufacturers have all of those sizes available.

All this assumes that the rims you are buying are the proper width for the tires.

:crazy: If you want to see what can happen by putting bigger fronts than rears on, here is this week's example of the effects of a mickey mouse setup on active handling:

:rolleyes: If you want to try a mouse setup and have to get rid of the tires, here is a good place to look for another pidgeon:

Be aware that everybody and their grandmother sells Z06 wheels. There are differences in appearance, quality, and width. Whatever you get stay away from screwing with your tire pressure sensors - just put them in the new wheels. You should only need air in the 30 psi range to start with - adjust up or down as you see fit.

If you are not comfortable with these concepts, try to find somebody reputable locally to help you. Even if it costs a few bucks more you can avoid a lot of headaches and have some recourse. It's not like putting new hubcaps on a Mustang.
