Corsa G+ came apart while riding

Luckily it happened going uphill, amazingly the tube stayed inflated.

The tread seemed to come away from the casing, and the tube pressure made the tyre bulge and deform. Happened with a bang, wheel sent a bit out of true as well.

    If it had been a car, I would've said ,'remould'
    Remember them?

    Look fairly new.
    I'd be contacting Vittoria to see if they are willing to help.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    I can't remember where I bought these from, I have a couple more spares than I bought from a forum member so I have a matching replacement ready to go. I'm not too bothered about chasing anyone for a free one.

    It does make you wonder about a particular tyre though when that happens. That's was with 85psi in it. If it happened on a fast descent it wouldn't bare thinking about.

    I was thinking about the wheel as much as the tyre.
    Plus, tyre R&D. Want to stop this happening again.

    The wheel is only ever so slightly out of true. The 1st photo looks like a quite buckled wheel but it is the way the deformed tyre is sitting.

    I'd definitely send that back to Vittoria as a safety/monitoring issue - this could highlight a manufacturing or QC problem that may need further investigation and/or correction. You were lucky...someone else might not be

    I had a similar issue. I noticed the tread was starting to separate from the carcass, but luckily before it got as bad as you experienced. I took it back to the shop, who then contacted Vittoria. Vittoria confirmed it was a manufacturing defect, and the shop replaced the tyres.
    The replacements have been fine, and I've got through quite a few of these tyres in the past without a problem. But yeh, I agree, a little disconcerting.

    I sent a photo to Vittoria in case they are interested.

    I love these tyres but this set will be my last, this seems to be a common problem with them! The pave`s were great and rubino controls are a good winter tyre but the corsa`s seem very fragile.

    You can still get Paves.

    This is a bit worrying as it's my go to tyre for the race bike. I realise it's likely to be a tiny proportion of their tyres but on such a safety critical item and one where I tend to think any of the major companies are within a gnats whisker of each other in terms of performance anyway it would put me off if this is more than a one off or near enough.

    I`m not that sure its a tiny proportion to be honest, its a real shame because in every other way they are a great tyre!

    You should have noticed cracking of the rubber thread before hand? I always inspect my tyres when I wash the bike, remove embedded flint and check for cracks... could be a storage issue... maybe they've been too cold/damp over the winter

    I had some Corsas which I really liked but they do seem very fragile.

    I was thinking about getting some more for my best bike but seeing stuff like this really puts me off.

    The idea is to buy them in spring, use them over the summer and bin them in the autumn. The problem is when these tyres hang around for ages. They are not meant to do that... the glue starts cracking, the rubber starts cracking...

    Bike stored indoors, checked over plenty as it is kept very clean so often I am looking up close, didn't notice anything before hand.

    Vittoria replied quickly, pointed that it could be under warranty and that would mean taking it up with the shop. Receipt long gone. Vittoria didn't ask to be sent it to look at.

    Aren't the G+ the older model? What I am trying to say is that maybe they've been kicking around for some time before you bought them, maybe stored in a warehouse in damp conditions or something

    Which was exactly how I used them. Had them on the bike for 2 summers & then started to get punctures so binned them.

    Nice tyres but certainly only for best & maybe not general use on UK (summer) roads.

    I was thinking about trying some Corsa Control's as they have a wee bit more puncture protection, £45 each though :/

    Yes, older model, so possible. Although I bought them when they were current and they've been stored inside then bike stored inside since fitting them. I think it's either a defect or maybe they are a bit of a time bomb because of the way they are made. Not sure.

    Anyway, it's all guesswork. I know two things, that the tyre is toast and I'm glad that it happened when going uphill.

    Maybe they've just been around too long and the glue has degraded. Which reminds me that I have a pair too, which has been around for a couple of years... maybe time to flog them to some punter on ebay... :D

    Yes could be old stock. I recently fitted some pro4s I forgot about then found in the garage. First ride was a hot day and the central strip on one is coming away at the edges and the sidewalls of both look like some kind of adhesive has seeped into them. No idea where or when I bought them but must be a few years.

    Just get rid of them and put some GP5000 on your wheelset.

    If you've got a batch number, can you DM me with it please as I'm running the same on the rear of the TT bike.
    I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.
