Painted the rotors and calipers this weekend and installed a set of drop shackles. Time to install the summer tires. As luck would have it, I found a nail in one of the rears, so I put the stock 17s back on the rear. Driving down the road the traction control kicked in, abs light came on, and the no hill assist warning came on. Is it because of the 23" front/ 17" rear combo, or did I screw something up putting on the shackles? Didn't pull anything loose with the shackle install, so I'm leaning toward the different tire size. What do you think?

Put the stock back on the front and see what happens.

different rotational diameter of the tires will be picked up by the wheel speed sensors....and shut down abs/traction and hill decent.....don't try 4x4.....if it locks in.....

I'm getting the tire plugged tommorow so l'll put the 23"s on see what happens.

If it is for a short period of time and you DON"T put it in 4wd you should be fine. The system thinks your tires are 'slipping' b/c they are spinning at different rates.

If you put it in 4x4 you will actually have a problem... 2 drive wheels trying to spin at different speeds.

It's always a good practice to put your spare on the front tire and rotate one of your fronts to the back if you get a flat out back. If you had a limited slip rear end you would burn the clutches out real fast driving like you did.

I've got a pair of 23's on the front, and the stock 17's on the rear.

Wheel size doesn't matter, it's the outside diameter of the tire. If the outside diameter of the tires for both the 23's and the 17's are the same, you should not be having an issue.

I didn't consider the limited slip in my post... good point.
