Hi all,

 

I’ve been experiencing some vibration through the steering wheel/drivers seat whilst travelling between 50 and 70 mph in our Octavia.
 

Somebody on here previously recommended that it could be a wheel alignment/balancing issue, so I took a trip to our local garage to have the balancing looked at today.
 

After looking at the rear tyres, they said both are ‘warped’. Looking at them myself, I can feel the tread wear is noticeably uneven on the inside on one, and in one spot in particular is lower than the rest of the tyre.

 

Replacing both tyres would probably solve the vibration issue for now, but are there any associated issues I should be looking to address to stop this happening again?

 

The garage suggested it could be a result of tyre damage/pothole damage etc, but seems odd it’s both sides.

 

Thanks in advance.

So you really need a 4 wheel alignment check carried out by someone with all the gear and training to use it and not just an idea.

Then the ability to deal with mis-alignment if there is any?

?

What tyres are on car, both rear and front, and how many miles have they covered?

?

Have they been moved front to rear in the past?

As above, before you put tyres on take it to a good place for 4-wheel alignment. having the old tyres on will help them diagnose the problem.

 

I would be tempted to find someone operating the 'Hunter' system, it is a capable system and people who operate them tend to have an idea what they are doing.

Some years ago I acquired a Lexus IS that seemed to lack stability on less than perfect road surfaces...and the rear tyres had uneven wear.

 

The solution was to firstly have a four wheel alignment done on a Hunter machine. The technician confided in me that in his experience it was mainly the rear suspension settings that were out,as they were on my car.

 

After the alignment there was an improvement,but it was only after replacing the unevenly worn tyres that the car felt 100%.

It is often referred to as sawtoothing and is an issue that affects a number of Skoda models, mainly the MkII Superb.

 

The inside of both rear tyres essentially takes the shape of the outer edge of a 50p piece which eventually results in droning and vibrations.

 

There'll be lots of threads on here mentioning saw toothing.

 

It is essentially an alignment issue, exacerbated with certain brands of tyres.

I had the same on my estate, changed the Bridgestone tyres and it went away ( tyres were very low).  Garage called it 'feathering'. He also said Estate cars which don't regularly carry weight in the rear and with the Bridgestone tyres were prone to it.  

Thanks for all these comments/suggestions - as a starting point I think I’ll go down the 4 wheel alignment/hunter route, to sort out any alignment issues.

 

The tyres are the factory fit p-zeros (19’ on xtremes), and are close to needing replacing. The car seems to have been susceptible to the vibration issue since we’ve owned it, but it has got noticeably worse recently, which might be because the uneven wear on the tyres has become more pronounced.

 

The front tyres are Goodyear ASY4s, and were only changed about 8k ago, so I don’t think it can be coming from them.

 

Ours is an estate as well, so interesting to hear about the weight in the boot issue!

Hint; those are usually used to prop up tyre test tables in magazines.

Definately the case, I was determined to see the tyres through to the wear bars, but towards the end the droning became unbearable 😂
