Punctured Tyres.

[grahamgreatbarr]

At a recent meeting of the Shropshire D.A. brains trust, the discussion got around to Tyron bands, alloy wheels and that rubber gungie stuff you pump into your tyres.

The debate started with the statement that:- If you had alloy wheels Tyron bands where not needed and that the rubber gungie stuff did the same job as Tyron bands and was much cheaper.

There was a very good discusion about the topic but a definite conclusion was not reached.

Has anyone got anything to add?

Tyrons and the gungie stuff are designed and do different jobs.The Tyrons are designed to stop the tyre coming off the rim in the event of a puncture or blow-out, thus hopefully avoiding the rim digging in to the road-surface, and therefore, the 'van overturning.To my mind, they are every bit as important on an alloy rim as they are on a steel rim.The rubber gungie stuff is a possible method of temporarily sealing a tyre after a puncture, but absolutely no use in the event of a blow-out.After using it, the tyre MUST be replaced ASAP, and tyre dealers hate working with the stuff, for obvious reasons.

I feel that the cause of most caravan tyre "blowouts" are the consequence of running the tyre too long on an undetected puncture.

The loss of air pressure due to the puncture causing the sidewalls to excessively flex and generate enough temperature for the structure to fail. Unlike with the vehicle we cant sense the puncture in the van.

Therefore the "gunge" ought if I am right to significantly reduce the incidence of blow-outs.

I am in the school that believes Tyron Bands serve more good than bad. I accept they increase the un-sprung weight, cost and tyre replacement hassle.

My take on it is basically this.

Despite modern safety rims tyres can come off, tyre dealers achieve this many times a day. However with the band they cant come off until it's first removed or the wire beads fail.

The drag on the failed wheel is potentially less with its fraying and rotating but retained tyre, than a skewed tyre leaving the rim possibly not rotating at that instant.

I feel it's this one sided drag that initiates the van instability that sometimes follows the blow-out and simply believe if this drag is reduced the potential for instability is also reduced.

I have had three blow-outs, in my thirty plus years towing, all with Tyrons, all non-events, no accidents, no damage, just a "B" hassle at the time.
