I got a 6th gen LX (I-4) sedan and been having vibration issues when driving. I got 17" ADR Reactions with Dunlop W-10 tires (215/45/17). The most obvious cause could be that the wheels are not balanced. Well, I've never really had this issue before and nothing has really changed with the wheels, unless a weight fell off. At high speeds, the car vibrates, not excessively but to a point where I notice it and it's annoying as hell. A few weeks ago, I had a flat tire, which I really didn't notice and drove a few miles on it, kinda ruining the sidewall (well atleast from the looks of it). I got it fixed but it seems like that's when the vibrations really started. I was thinking about replacing that tire but since I'm gonna be putting my stock wheels back on soon anyway, I'm just gonna leave it and replace the tires next spring since they'll be on the car for a few more weeks before the stock wheels/tires come back on.

One more thing, the rotors need to be replaced as well (pulsation when I brake). So what do you guys think the problem is... the bad tire, a bent rim, or the rotors that need to be replaced, or something else. I'm thinking maybe I should not really do anything to it untill I put my stock tires/rims back on and see if anything changes and then take it from there. Thanks.

 

You didn't notice your tire was flat Take care of your car first by getting it aligned, that will probably do the trick.

 

The tire could be damaged, most most likely you just need to have the wheels and tires re-balanced.

That will tell you if the tire or wheel is damaged.

Rotors will only cause shaking when you are braking, usually only at higher speeds. Rotors are an easy DIY job on your car.

 

if you bent the rim because of the flat, you'll have vibrations too.

 

If you drove with it flat for a while the sidewall may be trying to break down. Check the tire to see if there is cracking around the circumference of the sidewall, or anything that looks significantly different than the other tires more than just scuffed up). It could be a blowout waiting to happen.

BTW, if you lost a clamp-on wheel weight you should see a dirty spot where it used to be.

 

Using hubcentric rings?

 

Ok guys thanks for all your help. But got the car fixed and she's back to her normal self . As I had assumed and some of you had said, what happened was that after the flat and driving the car for a few miles on it, as well as hitting a nasty pothole, that tire was all screwed up. Even though it looked quite normal by just looking at it. I took the car in to have it re-balanced and I explained everything to the guys. They said they'll balance it and see what happens. All three tires were good and balanced out until they got the tire in question. That tire had a huge "bubble" around the outside and the inside of the tire was much much lower than that outer wall. They said that most likely the inside sidewall or the metals in the tire might have broken down and/or deformed to form that odd bubble. They also said that it was a blowout just waiting to happen. The funniest thing was that when they took the tire off and rolled it on the floor, instead of basically going straight like normal tires to, this tire would make a left circle. The car was due for new tires anyway, so I just ended getting new tires and the car is back to normal. Thank god it wasn't any worse than just that tire.

 

The bubble is your steel belt breaking. I'm surprised you didn't see it or hear it...when I blew a belt after hitting a curb it was super noisy. Glad it worked out :thumbup:
