Help with my new wheels..

Hello I installed this set of MB wheels with 33-12.5-15 Duratracs. Lately when I slow down and make a sharp turn left or right my brakes pedal vibrate like if the ABS was turning on. I assume that it has to do with the bigger tires Any ideas what this is and what do I do?
Thanks

Tire size should not cause the ABS to activate. I have 37's on 17" wheels and the ABS activates only after my butt has sucked up the seat cushion, not from simply turning.

Whats your setup? Are you running an aftermarket front bumper? i had this happen once on a freeway exit ramp that had a sharp left. Most agreed it was ABS. Which I agree. I was traveling 30mph or so on a downhill turn. Hasn't happened since then.
My jeep is very nose heavy and that contributed, I believe, to alot of brake dive going downhill. If you are flat when braking and turning and getting an ABS shudder, you might want to check your steering and suspension components.

Unless what your feeling is more of a shuddering and that's what you think feels like abs. Since your only on the brake when turning that might be why you feel it in your brakes. For some reason the tire could be rubbing against something?

The abs light doesn't turn on but it feels like when you slide on ice and pedal vibrated slightly.

If the ABs light does not come on, then I doubt it is the ABS activating.

Fitting 15" wheels on a JK presents some problems.
Namely that the brake calipers may have to be shaved with a grinder (Dremel Tool).
Maybe you should look at the clearance between the wheels and the brake calipers? Put some chalk on the edges of the calipers and then drive it. See if they are rubbing.

Your wheel shuddering problem

I may have found a solution to what you think is the ABS activating.
Replied to your thread, then searched and found this article to back up what I was trying to tell you: http://www.jkowners.com/forum/showthread.php?t=31104 Look at post #3, the one with the pictures.

You may want to see if the outer edges are rubbing against the 15" wheels. The wheels may be almost too small in diameter to fit around the JK calipers. A little shaving will solve this.

I hope this helps!
