hi i just got new tires and rims installed and my steering wheel vibrates going around 80 would these be a tire balnacing issue or allignment cause i know my alignment was way off on my old tires tommorow i will get a allignment

 

It could be both......i would have the tires re-balanced and have the alignment checked and re align if needed.

 

I would say balancing. An alignment would cause irregular wear.

 

You might want to jack up each tire and loosen your lug nuts, then evenly retorque them down again. If the shop put them on too tight and tightened them unevenly, you may get some shimmy from that.

 

I had a similar issue once I got an alignment. The alignment was done way out of spec. I had vibration at speeds >70 mph. I asked for opinions and got the following: steering stabilizer, bad/loose suspension components, tire balancing, etc. I know the tires were fine b/c they were brand new and they were balanced in front of my eyes.

A few others said to have the alignment checked and once the alignment was redone, the vibration went away. I don't want to guess what your problem may be but if this helps, great.

 

I'd try this first as I've experienced it firsthand. They put the tire back on and impact the lug ALL the way on and that gets the tire out of center just enough to make it shimmy. Loosen all the lugnuts until you can move the tire and then tighten them down in a star pattern gradually, not one all the way down at a time. Try a torque wrench as well (invest in one for yourself). 100-110 for steelies, 80-90 for alloys. (ft-lbs)

 

Ask shops to hand-torque to specs instead of just blasting them on. You'll have to return after a hundred or so miles for a retorque but I think it's worth it. One of the first things we learn when putting a tire on is to use a star pattern though I'm sure there's more than one idiot that doesn't do it even though it doesn't really take that much time. We've had them throw weights right away when someone used the wrong type for the rim style also.

 

do you think its would be the rotors

 

If it was while braking I'd wonder but that it started with the new tires and it's while driving, even though I'd heard the rotors can be warped by uneven over torquing, I'd start with some of these other ideas.

 

Worn shocks will cause abnormal tire wear, especially cupping and vibration at speed. Have them checked,usually oil leakage or spongy rebound, before any alignment.

 

A few other things to look at. First is if the tires have the paint marks to indicate their "heavy or high" point, make sure those are lined up over the valve stems, which usually are the wheels low point. I did this with my new BGF MTs, and had one take 0 weight, the other an ounce or two and they run neice and smooth. Then perhaps the new wheels were not balanced on a proper lug-centered machine or adapter. You might also cinsider having the shop that sold you the wheels dismount the tires and spin balance the wheels to see if they are out of whack by themselves.

 

well i got aligment done which was not the problem, a front end inspection was not the problem but it was the balancing it was 4-5 opunces off per tire so they fixed it and it is alot better now but still not as good as my old wheel and tire combo but the tread is alot bigger on my tires now oh well i get free lifetime balancing so i will just go back again and again
