Hi all,

Noticed a small bulge in the sidewall of my Veloflex Corsa, so took the tyre off to have a look.

Any thoughts on what could have caused the below? I've emailed the retailer who I bought it from requesting a replacement, but they have refused.

What do you think?

    It could be caused by the brake pads being set too high. The pads can contact the tyre sidewall causing rapid wear and separation similar to your photo.

    No. The fraying is on the bead, not the side wall. The pads are set correctly.

    Just to clarify, I didn't puncture. For the photo, I let the tyre down and took a section off the rim to see what was going on with the bulge in the side wall. This is what I found.

    if it's not the brake pads (seen this happen before) then sounds like you have a genuine claim for a new tyre - ask them again or offer to take them to court under sale of good act if they refuse (money claim online is cheap and easy to do)

    Well to me it looks like a defective tyre. The bit that's failed and allowed the bead to explode is normally protected sitting where it does below the hook of the rim. Is there anything rough / sharp inside the rim at that point?

    How old is the tyre and how much use has it had?

    If it's bead then it's hard for retailer to prove its not a manufacturing defect. Check consumers advice but I'm certain in the first six months the onus is on them to prove that it isn't - not for you to prove it is. Check online there is plenty good advice and template emails/letters etc to use. Stay firm and polite and state clearly what you expect them to do and quote relevant terms from Sale of Goods act. Even search on here this type of issue has been dealt with several times before and some members are pretty expert.

    That's what I thought, but the retailer is claiming that I have damaged the tyre.

    The tyre has done less than 300 miles. I put these on my best wheels so they only come out for sunny days. I've checked the wheel rim and all seems fine.

    This is the email i received from the retailer. I've sent them a reply.
    "Hello Mr Jolly
    The damage pictured is consistent with an incorrectly installed tyre, this damage can occur when tyre levers have been used with excessive force or the tyre has not been fully seated within the hook of the wheel rim. This is not something that would be deemed as a manufacturing fault and as such a replacement or refund cannot be issued.    "
