Blockley Inner Tube Failure

Post by 111Robin »

I have Blockley 145/80s with inner tubes on my Cooper (on D1s) and found a front fully deflated the other day. On removing the tube I found the valve had parted company with the tube. These were fitted two years ago and probably only covered 500 miles since. I've sent an email to them about it. Has anyone else had any issues ?. Hopefully it's a one off and not a poor material/manufacturing issue.

I'm not doubting the tyres, only the tubes. I was told at the time that D1s should be used with tubes, I know not everyone does but that's what I chose to do. Maybe safer without the tubes if they're going to fail like this.

Yup, That is certainly worth a bit of investigation.

The only time I have ever seen that happen before was in a tractor tyre where the tube had consistently been run at low pressure.

I'll see what they say however I'm guessing they will say I've been running at the wrong pressure to cover themselves. It's never been run at anything other than 28psi.

Have you checked for other holes in the tube? It might have damaged the valve as it went flat

Nothing to do with Blockley but I fitted a tube to a spare wheel with a period tyre and found it interesting that the design of a tubeless valve includes a seat for the rim but a tube valve doesn't. Does this mean the tube valves moves within the hole?
I'd be interested in hearing your views.

I’ve never had any luck with inner tubes. I also can’t see how having a deflated inner tube inside a tyre makes it any safer than not having one

The tube is fitted because the wheel doesn't have the additional profile that prevents the tyre from rolling off the rim and deflating during cornering. You can obviously choose to not fit a tube however I was advised to by Blockley when I bought the tyres.
