Tyre advice

[Rich K]

By chance I noticed a mark on the inside of my tyre upon investigation I saw this







since checked all others they are OK

I'm stunned, always thought I kept an eye on the condition of tyres, quick visual each time i leave the car, park on lock etc

what on earth could have caused this wear? there is no evidence of rubbing inside the wheel arch,
they are standard size tyre on the car.

[Rich K]

they are 234/45/ZR 17 on a 2007 Passat SEL 170

It drives very straight and true

is there a way of telling how old the tyre is as I have only had the car since Feb?
(pool car until I get my own car later this year)

What's the pressure like on it?

just been out to check .......... 32psi so a tad under

I disagree, the worn strip where the tear is appears smooth and blue with heat. I suspect the tyre has been rubbing on some element of the suspension or wheel arch area.

this was my first thought

had a good poke around when I swapped the wheel .......
there is no sign of rubbing on the strut or the plastic inner wing lining
it is stil covered with an even layer of road grime

If the tyre was made within the last ten years or so there'll be an oval shaped impression somewhere on the outer sidewall. It'll have four digits in it which'll tell you the week and year the tyre was manufactured I.e. 2809 would be the 28th week of 2009.
This tyre has been significantly damaged and if your car doesn't have any nasty driving characteristics i'd wonder if that tyre had been on a different car or your Passat has been damaged in the past and driven for a period with damaged suspension or no tyre pressure.

the code is 2110 so it's not that old

your other point is something I hadn't thought of.
I'll have a chat with the Boss tomorrow

BTW sorry to state the obvious, I'm sure your fully aware of this- but I wouldn't go anywhere on that tyre.

LOL ......... changed it as soon as I saw it

Thanks though

Many high powered FWD cars present with tyres wearing around the inside edge, nature of the beast, that tyre looks to be suffering this. OP states its a pool car so, chances are, it`s had a hard life.

How many miles has the tyre done?

FWD, 170bhp, PAS, pool car ~ 10 to 15K max would be in the ball park I would think.

My advice would be to get the car thoroughly checked out on a 4 wheel alignment jig, stick with Kumhos and move on.

the car has done 69000 but no idea when the tyre was fitted, the wear though is on the side rather than the standing road contact point.

there are signs of severe wear around the whole circumference.

What side was it fitted to? Nearside, by any chance?

it was on the front off-side (being rotational, always on this side)
the other 3 tyres are OK

[Rich K]

Had 2 new front tyres fitted

the fitters were sure it was a geometry issue, so that was checked
here are the results ......... I've no understanding of it
they were suprised not to see a conclusive reason for the wear

here are the check results for those who replied to my post
who are clearly more knowledgable than me and may well understand them



so the cause still is unknown.
(The car hasn't been in an accident)

Hammer67 said:

BTW what tyres did you have fitted?

I'll keep an eye on them as you suggest

Tyres I had fitted were Nexon N6000
the reports seem OK I know that they aren't a "branded" tyre
but for £160 a pair incl geometry check I though I'd give them a go
(the car should go in 6 months or so)

the car does mainly motorway work ... it'll be interesting to see how they wear
and perform.

I have "budget" 315/35/20 atturo tyres on my wifes mercedes and have been very pleased with them
good wear and wet performance.

it's not always spend more to get better......... hope the Nexen are as good.

[Rich K]

I can always turn the music up ...

Thanks for your input, James

Toe was out there.

Tyre damage looks consequent to that, apart from the tear. That could have been due to weakened structure because of the kerb or pothole impact (or similar) that caused the geo to be out in the first place.

No adjustments were made to the geometry ....... (I dont understand the numbers)

[Rich K]

thats a good thought

the springs on the struts are above the wheel space,so all OKthere.... could have happened in the past though

[Rich K]

all measurements were made once the new tyres were fitted
