So i bought a set of aftermarket rims and they aren't 100% true (round) so at low speed u get a small bit of wheel hop which is hardly noticable what so ever unless u have your foot off the gas doing 50km down a hill. but going access of 100kph the wheel starts to shake a small bit (going faster reduces it 120-140) and going even faster brings it back 150-180. now its not a oh **** this is scary vibration its more of the kind of vibration your grandfather would have on his back cushion on the low setting.

Basically what im saying is, will this damage my suspension, should i get these rims off and put my old ones back on. buying things of craigslist aren't always a good idea

if the wheel is bouncing constantly like that, i'm sure it will destroy your wheel bearings, and i am certain the rest of your suspension wont be happy about the excessive bouncing.

Is it all the wheels out of round? did you get them balanced? Did the new set require hub-centric rings? etc?

Is the shake ALL the time? I don't see why it would disappear at different speeds, the rim is moving ALL the time unless stopped of course, and therefore it should produce a wobble/vibration at all speeds, on acceleration and braking, in neutral....

the small wheel bounce is strictly between about 45-55 kph and vibration dont start until just over 100kph. yes hub rings were used, the rim it self it not round i went back to have my wheels rebalanced after i noticed it and on the balanced i watched it go around the rim moved up and down i would say about 3mms

hmph well if the vibration/hop wasn't there before you put um on i guess the problem can only lie in the rims and tires.

its up to you what to do of course, You may get away for a while if you leave it, but things will probably wear prematurely in the suspension from the extra stress.

thats not good...

I say return those rims and get your money back.

cant really return craiglist rims... knock on the door. I wana refund, u sold me broke rims. "No you broke them" *SLAM*

Well, nothing else you can do about it. Might as well put it back on craigslist and sell it to the next sucker in line.

soon as i finish reman'ing my factory mags i will.!

thanks

all 4 are bad?.....if its just one maybe you can find just a single replasment

I hope its just one. not sure if its Driver or Passanger front

did you get the rims balanced and checked before you put it on your car???

balanced yes

To be honest that sounds like the bearings are already going. I had a another vehicle do that..won't say what type, but exactly like a corolla, it would only shake or make noise at about 40-50 mph, then go away. Turned out to be the bearing in the wheel hub, i ran it so long that when i finally fixed it, the wheel would lock up, and when taken off black pieces of metal feel out. I would check that out..quickly....with so many rpm's many things can happen to many parts.

Not the bearings, as stated earlier its ACTUALY THE RIM THATS NOT 100% ROUND not my suspension!!!!!!!!!!!!

Figure this -> as you increase in speed that small amount of unevenness will go away from the fact that the wheel is rotating quicker to the point where force is applied to the tire it self pushing outwards and actualy evening out that play in the rubber making the rubber 100% true altho the rim is out, But saying that if u go to fast the problem reoccurs because too much outward force is being placed and putting the wheel out even more.

You say soo many RPM's -> An engine can rev 7000RPM at 245MPH but the tire is only spinning at 1107RPM Daily driving at 45MPH that is only 220rpm

You can delete/clost this topic, i took a 30ton micropress to my rim, its 100% true

Well congratz on fixing it, hope it stop shaking now!

Not a mechanic, just talking from past experiance, but happy you got it fixed.

well if your smarter than me you would just repalce the rim cuz stopping production so i could risk my 180$ rim on pretty much pure luck

o.k.
