Hi LS4 Guys I'm new to the forum, you guys rock!!
I have a 2007 Monte Carlo SS:
I'm unfortunately starting my new thread with an issue I have. I just recieved my aftermarket 18 inch wheel and tire package(Exel DL-46 wrapped in N3000 245 45R18 Z rated tires). They are mounted and balanced, but at around 50-60mph, I feel significant vibration through the steering wheel and elsewhere. But at higher AND lower speeds it seems to goes away.:confused: Could it be just the breaking in of the new tires, bad balance, low profile!? what gives? thanks guys,.............

i would check the sticky about asa wheels. you might need a spacer.

yeah, thanks neilownz for the advice but I just took it up to my good friends at a famous tire shop and we rebalanced them and she rides so much smoother now!!! Wheel Max is where I ordered these tires and they balanced them with some type of stactic mounting blah blah thing a ma jig! But we proceeded to take those pantsy things off and remount with the standard procedure and she rides good now!!! So maybe if anyone's thinking to purchase a tire package from wheelmax you would probaly better to just order them without them being mounted & balanced!! Simply because you may have to rebalance the damn things!

You might need a set of "hub-centric rings" they help to pretty much eliminate that 50-60 mph vibration.
