i have bought 4 new tires since and balance them and still vibrates between 60 and 80...how do you check if your rims are bent.......as far as i can seei dont even see a scratch.......

 

Well now there's your problem. Somebody put some routers on your wheels....

J/K..... I know what you mean. Sounds like a balance problem to me and the tire shop needs to fix it for you. If they balanced the wheels and tires when you had them mounted then they shouldn't charge you to get it right.

 

The cookin' kind.

 

i baught the rims off a friend they are in mint condition but i also think it is the balance when they arnt balance then your car vibrates and when they are not alineged then your car pulls a certain directions am i right or wrong?

 

Auto/Aviation. You guys are such haters man. Do you have nothing better to do than bash other users? Try to help a man out and I catch flack. Could I diagnose that problem? Not from Germany, but answering the questions I asked could greatly narrow it down. I have an idea...go buy a Mustang because you guys and Mustang drivers are of the same caliber.

 

Since you put aftermarket rims on, check to see if the rims are hubcentric. Meaning the main hub in the center of the brake that the wheels fit onto. If there is as much as a .25 mm difference, you will get vibration. You may need a hub centric spacer.

Option 2: Make sure the lug nuts on the new rims fit the diameter of the new wheels. If the old lugs do not go inside each of the lug holes, you will get vibration. You may need new lug nuts. Lug centric is the term for this. Sometimes it is a combination of both.

Other option is a bent rim, or a tire (s) with a steel belt that is warped. If the wheels balanced out, it is definately something else.

Just a few options.

I'm a new poster to here, but not to forums. Currently on G35 driver for my 08 G35S, previously on Sweedespeed, SaabCentral, and Grand Cherokee SRT8. I'm big on aftermarket rims, so this is where the above comes from. And buying a 350Z in the next month or so as my second car.

thanks alot man ill deff check all that out

 

I was not hating. You just threw that "i'm a mechanic" line in there which threw me off because it has nothing to do with your issue unless you are automotive mechanic.

It doesn't matter where you are from, you make it seem like if you were from Germany, nobody would help you. Vibration issues are not straightforward to diagnose.

The best thing to do is what you are probably going to do anyways, take it to a shop to get it looked at. Hope everything works out for you (350zFreak).

 

I think he metioned that he is an AUTO(mobile)/AVIATION mechanic. And i agree a lot of people in this forum hate on a lot of other members especially newbies. For the love of God, if you have nothing to contribute to the topic, don't type sh*t. And as for the vibrations, I'm almost sure that its balancing or wheel damage. The vibrations differ in frequency and/or intensity depending on the rotational speed the wheel.
Alignment problems will have your car pull to the right or left.

 

Okay there is a confusion, the guy with the problem is 350zFreak05
Spirey was trying to give ideas to fix the issue. I originally thought it was Spirey with the car issue, which is not the case. I apologize

 

No harm done. In my experience 350zFreak05, it is either the balancing or the tires that causes vibration. 9 out of 10 times it is going to be the balancing. Although, my beater had the same problem last year and it was due to a broken tire bead, or warped band as ParkStr8 said on one tire. My advice, start small, ie. balance. Next I would swap to another set of tires and rims completely, if available to you, to see if it still does it. ParkStr8 had some good pointers too, as I am not big on aftermarket rims. Good luck man.

 

What you guys need are hubcentric rings. They slip in the hub of the new wheel so they fit snug on the hub of your car. This way the wheel sits centered on your hub. You will need to measure the hub on the new wheel and get the dimensions of the hub on your Z. Any wheel and tire shop should sell them. I think there 3 bucks a piece and there called hubcentric rings.
