Does it shake a bit? or should it be perfectly still?

 

they should be perfectly straight

 

it's always different.

rotate your tires.
see if it changes.
it's not a corvette.

the tires...the stoopit NJ roads..
phfffff.
how many miles on tires?.

and..NJTLS...."they should be perfectly straight"..

what is that?..

u mean all 4 wheels, should be str8t?.

lol?..

 

seems like it could be you need to balance your tires. You probably hit a pothole or something and your wheel might be slightly bent. Either way, looks like you should balance your tires.

 

I am smooth as glass. Get your tires rebalanced. Take it to a Discount Tire if you have one near you and have them Road Force balanced. This machine will determine if you have problems with your wheels, tires or both. PRetty slick.

 

Perfectly still now, it use to shake when I needed rotors and an alignment.

 

For me, ever since I changed to my Conti Extremes, my steering wheel started to vibrate and shake at speeds over 50mph. Then I took it back to my tire shop had then rebalance all the wheels, and he said that all my wheels had slight bends in them, god dam NYC roads!! He rebalanced them to about 1/1000ths he said and made up for most of the bending, and the shaking of the steering wheel did subside a little, but its still there.

What I want to know is, this only happened to me immediately when I took off my Michelin Stock Tires and went to the Conti's. Do the Michelin Stock Tires just a do a better job of evening out the bends in the rims so you dont feel it in your steering wheel?

BTW, I had a wheel alignment done 2x and rebalaced it 3x and rotated my tires 2x already so I know it isnt that.

 

It does not shake. Perfectly even.

 

Well, here's a question for you: Is the side wall in the Conti stiffer or softer than the Michelins? That could play into how much of a shock your rim experiences when you driving into a pothole. In any case, rims can bend in such a way that is not readily visible to the eye, even if you are looking at the rim without a tire mounted on it.

CJITTY is right about getting a road force balancing. Essentially this type of balancing applies force to the tire, via a rolling pin type structure, while the tire is being spun on the balancing machine. This force helps to simulate how much your rim flexes under load. If a rhythmic force is observed by the rolling pin, the wheel is out-of-round.

A regular balancing machine assumes that the rims are not bent. With such an assumption in place, one could balance a brick on that machine. And it would eventually balance to zero!

Anyway, I had a problem like that where I hit something (like a brick...) on the Taconic. I made it home ok, but then the next day I noticed a bubble in my tire. I had the tire replaced but still had serious vibration at ....let's say, speeds slightly above 65mph. I took it to the shop and no one could find a problem with the rim visually and it balanced out OK on a regular balancing machine. I suspect it was actually bent along the 5 star spokes!

I got a flyer in from tirerack talking about that road force balancing issue. I didn't bother to look for a shop that had that type of machine because I already knew which rim was bad, partly from the bubble in the old tire and from swapping the rims around to see what vibrated... at speed and what didn't.

So, I took a leap of faith and bought a new TL type S rim from this site.... that did it! I had that "smmmmooooth as glass" ride again.

 

I have a very very very slight shake, not even a shake, more like a vibration. I dont know if it's the road or wheels. It's not noticable at all, only noticed it during lunch today after reading this thread. could be that I have the 18's on and it's just the road that's shaking?

 

my viberates at high speed. During street driving, the steering is perfectly still. I recently changed to Good Year tires and ever since that... I don't feel as good as my previous michilin. I am just concern that It might be my car. I don't know. I took it to the dealer and they said its fine, but I swear... my car don't feel as smooth as before.

???

 

Check the load rating of your tires ... the sidewalls might not be as reinforced as OEM Michelin (load rating 93XL, I believe)

Or it could be a bend somewhere on the rim, as others have suggested.

Who knows? So many factors involved with steering wheel shake (rotors, alignment, tire, rim, etc)

Sorry -- this doesn't contribute to the thread...

your stearing wheel is not supposed to shake at all , get an alignment then take it to ur dealer just my .02

 

Well, ur right, the side wall on the conti is much stiffer than the side wall of the Michelin. Isn't this the reason why the Michelin Bubbles so easily to begin with? And I had a feeling that it could be due to this but didnt think that the steering would vibrate slightly at highway speeds. The only thing that I didnt try is this new thing you guys are talking about called Road Force Balancing. I mean do you think it would solve my issue or would it still be there due to the bend in the rim and type of tire I have?

 

Zero shake

if you have a speed sensitive shake then it's definately wheel balancing

if it's when you lightly brake then it's pads/rotors

That type of balancing will solve at least half of your problem. It would help to identify which of your rims are out-of-round relative to the road surface.

In other words, it would show if your rims are slightly oval as opposed to completely circular, it would also show if your rims are bend off access (kind of like a bicycle tire after it's been beat on, and needs it's spokes adjusted to straighten it again).

Come to think of it, I don't think Enkei rims are that strong to begin with. So, a stiffer sidewall combined with alot of potholes could spell bad news.

Sadly though, if either of these types of bends turn out to be the reason for your vibrations you'll need to spring for new rims to replace the bent ones.

Interestingly enough the rear end of our TLs do a heck of a job isolating vibration. When I put my bent rim on the back of my car I could bearly feel it. But when that rim was mounted up front I thought the car was going to fall apart. Mind you, I'm talking about feeling vibrations at speeds of 80+.

Short of finding a tire shop with one of these special balancing machines, you might want to do some wheel swapping to see if you can identify the bad rim(s). Take the front wheels and mount them in the back and mount the back ones in the front and see if there's a difference in feel.

 

The Contis have an issue with flatspotting. My car has had a shaking issue ever since I had the Contis mounted in December. It gets a little better with rebalancing, but it is still there. Not satisfied at all.

 

even if it shakes, it's becoz the road is in bad condition and coz it shake

it does happen after a damn long icy winter
