My 05 (sedan) just had new wheels and tires, 17 inch, put on. When braking I now feel a slight pulse in the brake pedal at 45MPH and over and then it fades away. No vibrations at highway speeds when not on the brake.Feels like a warped rotor but I never felt it with the 15 inch stock tires. Car has 400 miles on it. Anyone know if they have come through with bad rotors. Thanks for your thoughts. :confused:

Well I would say one of the wheels could be off weighted but I would think that that would make it vibrate at higher speeds and u said its not so... :confused:

Just puttin new rims on shouldnt mess with the brakes, unless the brakes aren't powerful enough for the bigger wheel maybe.

The tire size incresse may be causeing the brakes to not work properly and you sould get bigger and better brakes to make up the difference of the extra weight because of the rims. That should take care of the problem MAYBE i am not 100% sure but i think the added weght might be it.

OK, here s the update. Put original wheels back on and car is fine. So, something the idoits at the wheel place can t find. Returned wheels for full refund and went to another wheel place. Got new rims and Toyo Proxis and have no problems.

It doesn't sound like this was your problem, but here's some useful info....

Whenever you install wheels, always ALWAYS torque the wheel nuts to the PROPER torque and in the correct sequence.

Most tire places don't do this. They have a guy that stands there with an impact gun, and blasts the nuts on there at 100lbft without paying any attention to the manufacturer's recommended setting.

That can warp your brake rotors (warped rotors manifest themselves as a pulsating feeling in the pedal whenever the brakes are applied). Too much torque on the wheel nuts, and especially uneven torque (ie, one at 100lbft, one at 80, onr at 90, etc.) will create uneven pressure on different parts of the rotor and can cause them to warp. Especially if the rotors aren't top-quality to begin with. (we all know how fantastic GM's brakes are....)

Invest in a good torque wrench and always torque the bolts in the correct sequence (zig-zag for 4-bolt wheels, star-pattern for 5-bolts) and to the correct torque, and your brakes will thank you...

Dan is 100% on the money. I think also that the retaining clips for the rotors sit where the hub meets the rim and on the aftermarket wheel those clips came in contact with the rim making an uneven fit. The factory steel rim had spacing where they meet because it did not sit flat against the rotor like the aftermarket wheel. Clips had to be removed. The first guy didn t do that.Alot to consider when changing wheels.A little confusing but you get the idea.

These "CLIPS" are the same thing that happened to alot of SRT-4 owners. They need to be removed when you go to aftermarket wheels. This was more than likely your problem. Needing bigger brakes is/was not the problem. The time for upgraded brakes is for when you RR or autocross and want the extra clamping and less fade. They are properly sized for you from the factory to stop that weight. If you wanted to stop faster/harder then upgrade. But the brakes themselves are not the reason behind wheel wobble. It would take an improper torqued wheel and a warped ROTOR (not Brake assembly, it wont warp like that) to wobble you like that.

yea, they had other customers around and I started getting pissed off. Also I told him I paid with a credit card and I would just dispute the payment with the card company and in the mean time he would not have his wheels back or the payment from the credit card. :D
