Hi guys, the "ABS" the "VDC OFF" and "SLIP" comes on after i put on the new wheels. I did not get new tires, i only switch the tires from my stock rims over.

My new rims specs are 18x8.5 and 18.9.5

tires are 215/40/18front and 255/45/18rear

Help meee please ladies and gentlemen!

 

Front tire size is to small..

 

what he said. Spend some time on http://www.rimsntires.com/specs.jsp figuring out the controls and it will tell you when you are too far off with your upgraded tires/rims. Note the site only does one axle at a time so if you are screwing up both axles that combined deviation from norm needs to be accounted for.

 

U need 225-235/45..

 

Those are the same tires i used on my stock rims

But heres another symptom. While driving, i hear a short 2-3second hissing sound coming from the front, like some hydraulic tryin to pump something. When that jappens, the brake pedal gets harder, then when i push it down hard, it vibrates like the ABS
