Vibrations at high speed

DCEite · 10th June 2007, 13:39

I have a 2004 model wagonR lxi, with stock tyres, run 30k kms.
The issue is that the car starts to vibrate at anything excess of 70-80kmph. It was not the case till an year back @ about 20k kms, it used to do speeds in excess of 100 and still felt sure footed and stable. But now, it starts vibrating (the vibrations are more pronounced on the steering wheel).
Any inputs?

Have you checked alignment and balancing ?

iraghava · 10th June 2007, 13:45

Wheel Balancing is out, get them balanced again. Otherwise check if your tyres have any bulges.

Get Alignment and Balancing done. As you are running stock tyres and wheels it should be the problem with Balancing. OR uneven wear tear of tyres can also cause this.

But experts can shed more light on this

i had the same problem with mu suzi. further inspection of the front tyre showed uneven wear on the inseam which was prominent on the drivers side. i took it for wheel balancing where the guy told me i needed a fresh set of bearings as my existing ones had worn out. drove it straight to MASS and got the bearings replaced.
And me and my suzi lived happily ever after!!

Wheel balancing is out...!!
BTW What tyres do u have? S322/JKtyre??
Time to get new set of tyres i guess

i had the same problem above 100kph and i got the wheels rebalanced and things were fine... So, get it checked for wheel balancing

Balancing is out. Had the same problem with my OHC.
Got the wheels balanced & alignment checked, the problem dissappeared.

I have same problem with my baleno now. whenever i try a speed of over 85 kph it starts vibrating as if its out of breath. iam running on 14" tubeless with alloys and think its the problem with wheel alignment. 3rd service is due now and should try out that...

Vbration at high speeds is sure signs of balancing, if balancing doesn't take the problem away, then there are some serious complications for sure.

I dont think its the problem with the alignment. Get all the tires balanced .It should solve the problem and dont wait till the service. Get it done from outside and you will come to know what the real issue is.

Yes i had a recent spate of tyre punctures, so i think balancing and alignment is the need of the hour.
KP, they are S322s. Whats the life of stock tyres. Should i go for the change now?

S322s are hard compound tyres which normally have a life of at least 50k kms.. But in our extreme climate in North where the temp varies from 5-50 degree C...& also the rains when the roads turn into rivers these tyres become harder & start making a lot of noise...
I had MRFs in my Zen which had done 30k kms and had more than 30% thread left but had to change them as they had become too hard & were making a lot of noise..

I previously had S322 tubetype tyres (OEM). After about 6 years and 34000 kms there were bad vibrations at the steering wheel and the car was pulling to the right. Upon checking the front left tyre had developed a flat spot. These flat spots could appear when the tyres have relatively less tread left and when one does hard braking/cornering on surfaces like the concrete on the Mumbai-Pune Expressway. There was about 2-3 mm tread left on all tyres and the wear was uneven, indicating alignment problems. There were also some minor bends in my rims; could have caused balancing problems as well. Since then I have shifted to tubeless tyres (again S322) and alloys and get my alignment/balancing checked at a good tyre shop rather than my local garage. So far no problems after about 17000 kms. I expect a tyre life of only about 30000 kms because of the high-speed driving on the Mumbai-Pune Expressway every week.

one of ur tyre is either out of balance or alignment.

if thats not the case then its sure One of the tyre failure. tyre lost shape outer section - contact patch. this can be felt at speeds above 90kmph when the entire car can vibrate and sending lots of feedback in the steering also can be felt when speed is 3 to 10kmph a swaying kind of motion.
