Some advice on my bulge please

[BigonaBianchi]

how do you know that your guage is that accurate? just a random thought...

well i use a balckburn track pump...i guess i have to accept the guage is accurate, it's certainly been fine up until now and also on the other bikes.....but yes, i guess there is a slight possibilty its developed a fault, but i really doubt it.

I only say so because we have 2 leyzene pumps with gauges and a JoeBlow track pump and they give completely different results...

I'd be surprised if any of them were particularly accurate, but equally the tyre shouldn't be that sensitive to being a little overpressurised and if my Joe Blow is anything to go by when you're getting in to three figures it's more likely to be under than over. My money would be a bad batch of tyres that got missed on quality control. Maybe cured badly, or exposed to something they shouldn't have been. Considering the size of the market place a small number of tyres could end up quite thinly distributed so you'd get the odd failure here and there.

That's exactly what happened to me!

maybe wrong - but that tread looks well past its 'sell by date'' anyway

seems more prevalent now sellers are sourcing from China
my original Conti ULTRA were fine
new Chinese ones came with split in sidewall

.
and more dangerous - air bubble pockets in the tread


INSTANTLY REFUNDED........still worrying though

and there was me thinking those were wear marks. when they are gone, the tyre needs replacing...am I wrong is this assumption?

never seen this before EVER

and they were deep

 

[slowmotion]

On the way to Whitstable a couple of months ago I had (a) a puncture, (b) a bulge) and (c) an almighty explosion all in the space of about 20 minutes. It was the front tyre too so it could have been a bit nasty if I was going at any speed. BTW, it was Vittoria Zafiro.
Bin your tyre.

Deeper the better as that's the amount of tread you have , only seen them on Contis so if your new to that brand then is easy mistake to make .

Oops , what ebay shop was it btw?

 

[John the Canuck]

Oops , what ebay shop was it btw?

i realize i prob wouldn't get problems with £30-40 tyres - but i fund my cycling from pensions
and - with low annual mileage - tend to buy budget tyres

Schwalbe Luganos 700x25c for the Peugeot Loire = well pleased from hopkinsoncycles on eBay
wire bead for the steel rims

the Conti ULTRA Sport 700x23c was 1 tyre to replace one with a cut sidewall on the Premiere
bought from 'gearchangers' on eBay - but subsequent emails were from PEDAL-PEDAL-Ltd
refund was no problem

then 2 - Mavic Aksion 700x25c [to replace the Contis ] were from Planet-X

That's goosed. I had something similar from a Lugano at 110psi and it blew up on a downhill. Fortunately it was my rear and I was able to control my speed. Get it binned and replaced with something from Continental.
