I just put on a set of RaceStar wheels, 15x10 in the rear with a set of Mickey Thompson Drag Radials 295-55-15 tires...

And now my abs inop and brake and tcs off lights are on?

The tire is 27.7 inches tall the factory tire was a 245/50/16 and it was 25.6 inches tall...

What can be done to get these lights off?

Thanks for your time and suggestions in advance

 

same problem here ...

this is a common problem with fbodies .. if am right ?

 

i have heard the 99+ cars have problems if you are running different wheel sizes in the front or in the back. are you running front runners or just a stock wheel in the front

 

the only way to get the lights out is run the same size tires front and back, if you run 27's or 28's on the back with a 26 front runner its gonna through the computer for a loop because of the 2 different sizes.

 

Correct. I don't think it's hurting anything so don't worry about it.

 

Thanks for all the input...

And yes i have 26inch tires in the front and 28 in the rear...

 

This is normal if you're running a taller tire in the rear. If you want the lights off, put a 26" tire in the rear. The lights being on don't hurt anything.
