What causes this?

[Mishy]

Have you seen this before on other Continental tyres Hamish?

Hey Shaun,
I'm not sure what brand this tyre is, but the little "patches" are not uncommon.
As far as the head shake goes, it's suspicious that it appeared at the same time as a tyre fitment, but could (as I'm sure you have picked) be one of many things.
I have come across several dealerships who have poor wheel balancing gear, which is one possibility. Another I have struck recently is a wheel bearing fitment fault.
More info would be the trick, although I think you would have to have the bike to get to the bottom of it.

Hey Mishy, it is a Continental

[YellowDog]

Those marks appear (to me) to be heat related.

If te wheels have been balanced with the new tyres, then you shouldn't get such patches.

I'd take them around to the tyre shop and see if they can explain it.

Good luck.

You are of course correct, however, I assure you that the identification was purely accidental and must confess to being a numb nuts for not checking the photos carefully enough in this instance. At least I got the important stuff right, there are no chicken strips showing eh.

My post was a genuine request for information and not an attempt to name and shame. I humbly apologise to Conti

Big of you to type this Stranger.

I was not trying to aid the nameing and shameing game, just pointing out the fact that your problem is with the said brand, and hope fully Hamish will be able to come up with a valid tech awnser to what has gone wrong with there brand, as I know they are serious, and do not want any trouble product out there

Its inside out.....

[Kickaha]

heh, I have nine vehicles registered on the road, and I have been buying tyres for thirty years, and any brand that I have had a fault on a NEW tyre like that, I will ditch them and never use them again. You should, of course, do as you choose.

There isn't a brand in the world that hasn't had a fault at some time or another

One thing with static balancing is even when you get it to zero you will generally be left with some dynamic imbalance but If it starts to shake at lower speed and gets worse and worse as you increase speed I would be looking at uniformity rather than balance

[R-Soul]

Could it be innacutaye fitment of the wheel? Something changed when the tyre was changed. So its:

- wheels fooked or
- fitment fooked, or
- bearings fooked.

Were they beaded out evenly , with the asian Contis and Michies getting an even bead can take some time . Never had much of a problem with the cities before , good option for the little ones .
