Tyre jumping

m8002? · 1st June 2009, 17:35

I did the 35K routine maintenance on my baleno last weekend. After the service, went out with the service advisor and could hear a light sound in the front right tyre. The SA said its tyre jumping. When asked the reason..he said its because of some hardening in the tyre and its ok to use it.

I checked if i can use it as a stepney since i will be doing some highway runs..he said its ok to use them..doesnt see any issue even on highways except for the small sound.

Now the question for the experts:
1. Some googling shows wrong balancing also causes jumping. They had done balancing and rotation as part of the service. Your suggestions on what could be causing it?
2. How safe is this tyre now? Is it better i use it as stepney for emergency. I am anyways planning to replace all the tyres in another 2-3 months?

Can you see/feel any bulges? I'd suggest you get it on a balancing machine and check out yourself what it says.

Yeah, +1 to that.
Get it balanced first.

How old is this tyre ?
How many kms ?
How is the condition of the tyre ?
(tread wear is even ? any sign of old age ?(small hairline cracks))

Not sure if you tried this, did you try putting it on a (say front left) does it "jump" ?

A tyre jumping around

1. Balancing is incorrect.
2. Tyre is really bad (uneven wear and all that)
3. A bad damper. (the thing inside the spring in the suspension thingy)

Did you get the pressure checked? If a particular tyre is overinflated, it can jump around.

Other reasons as others have pointed out are due to bad balancing and an unevenly worn tyre.

How old is the tyre? Which make and size?

In addition to what the others have already said, please have the wheel/rim checked for warping and bends.

Cheers,

Thanks for the suggestions guys. I just wanted to get opinions before approaching them for balancing again.

Its 185/65R14 Goodyear NCT5s, mounted on alloys run 36K kms. Balancing, rotation, alignment done every 5K kms and there is no uneven wear or bulges. My guess is they screwed up the balancing this time.

just check if tyre is flatspotted, tyre jumping is quite possible if so.
