Punchture Repair Kit ( Not Gel Type)

[chav4boy]

Do you think the not gel puncture repair kit are useful, i'm a rav 4 sr180 owner so i have been looking into ways of avoiding the down time associated with a Bridgestone BSR flat,

interesting .... now, where's that wheelbarrow? Could save the nations builders a fortune! Do you know how many barrows go into landfill cos the tyres gone flat???

Regarding the car tyre - I'd be a bit worried about using the 1st method on a tyre that will run at speed.

The 2nd fix reads better, although again I'm not sure how it would behave on some of the tyres types. Is it strong enough to be used on a higher pressure low profile tyre???

Mechanically, the use of the mushroom plug seems more logical, but of course you then need to get the tyre off which must cause a little damage.....

So - its a don't knock it until its tried....but apart from my wheelbarrows, I won't be trying them.

(For information, and to warn children who may read this, I do not support the running of wheelbarrows at anything over 18mph. If you do intend to run a wheelbarrow above 18mph, and use these products, get your parents/carers/guardians permission first). Speeds of over 45mph should only be attempted by professional wheelbarrow drivers, adequately trained in the Hazards involved and having completed a Hazard Analysis and Critical Control Points (HACCP) study of this activity.

Users of 2-wheeled wheelbarrows should be aware of the dangers of sudden deflation of 1 tyre causing potential multiple pile-ups at the skip. The likelihood of a double deflation on a correctly maintained wheelbarrow is slim, but should, nevertheless, be minimised by the removal of joiners waste (nails and screws) safely.

this type of puncture repair is standard practice for the motor biker gang, where the speeds/stresses on the repair would be higher ,i would of thought, the big advantages i can see are,the repair is quick, you don't have to take the wheel off the vehicle, and you may not have to worry about finding a specialist garage for the support ring work, if you have the run flat tyres, also i understand that tyre repairers tend to replace tyres on a wheel that have been gel/sealant repaired

here are the instructions from the maker

I'd guess the rubber compound used on bike tyres is softer, in comparison to some of the reinforced tyres and low profile stuff kicking about for 4-wheelers.

The run flat is, I think, a reinforced construction, but I don't know anything about their rubber as I haven't worked with any.

The other thing is the weight of a car on 4 wheels is different (gosh) to the weight of a bike on 2 wheels....and the recent RAVs are no lightweights...especially those with 5 doors :lol:

They both seem a very good standby to have with you - especially if there is not a runflat tyre repair shop within easy distance if you get a puncture - might well give you many more miles to get back home etc. at a higher speed than the max 50mph recommended with a punctured run flat - If someone tries a kit or gets one please let me know!

Puncture Treatments

Various puncture treatments, or sealants, are available on the aftermarket. They basically fall into two groups. Those applied to the tyre from new and those applied to the tyre following a deflation. There are conflicting views from tyre manufacturers regarding the use of these sealants.

It is claimed by some that sealants used from new can have the effect of masking, by sealing, a puncture in a tyre that may have caused damage that, were it noticed, would render the tyre unfit for further use.

Sealants inserted into the tyre from new work by forming a film over the inner surface of the tyre. When a penetration occurs the air pressure within the tyre forces the sealant into the injury. This type of sealant is particularly popular with operators of small off road tractors and lawn mowers that, due to the tyre design, are susceptible to punctures by small thorns etc.

The other type of sealant is injected into a tyre from a pressurised canister following a tyre deflation. The contents of the canister will both seal the leak in the tyre and re-inflate it enough to continue a journey.

It is generally accepted that puncture sealants used on road going vehicles should be treated as a temporary repair only and that tyres suffering a deflation should always be checked by a qualified tyre technician for further damage.

In some cases the injection of a sealant is classed as a modification to the tyre and may invalidate the tyre warranty. If in doubt it is recommended to check with the tyre manufacturer concerned.

As far as I know the RAV runflat tyres aren't actually "runflat" tyres, the Bridgestone BSR system is a support ring which is attached to the whhel, when the tyres goes flat the support ring takes the strain and prevents you running the tyre on the rim...

...The tyre itself could just be of normal contruction. Like I said this is "as far as I know", although I'm a tyre fitter our garage is not a Toyota or Bridgestone approoved/trained centre for doing the BRS systems and as such I have had no personal experience of them. Having said that, Bridgestone "runflat" tyres... as in the proper tyre with the self supporting sidewall.. are normally marked RFT, so if the RAV tyres are RFT tyres then they have self supporting sidewalls as well as the BSR System... which I think unlikely.

As for doing puncture repairs on "runflat" tyres (I'm not including the BSR SSystem here as I don't know the construction of the tyres) personally I don't think they should be repaired at all... here's why.

Bridgestone have recently changed their minds on this issue, it was once the case that their RFT tyres should NOT be repaired, we found this out when we refused to repair a tyre on a BMW, the costomer checked with Bridgestone and was informed that one repair per tyre is permitted. As this was the opposite to ALL the informatiom we had we also checked and were told that Bridgestone had recently changed their policy (we think this was because they were loosing buisness to Goodyear when it came to replacing tyres as Goodyear always permitted one repair).

On "runflat" tyres it is stated that the "tyre should not be reinflated or repaired after runflat operation". How are us tyre fitters supposed to know if the costomer has run the tyre with no pressure? The costomer knows how much the tyre will cost, so when asked if they have run the tyre flat the answer is ALWAYS no, so are we to take the costomers word for it and put peoples lifes at risk?? Even after runflat operation there can be no visable signs of damage, however the tyre could well be in a dangerous condition within it's construction. It also stated that if the have been driven at over 50mph with no pressure it cannot be repaired.. again, how do tyre fitters know it hasn't been run at speeds over 50mph?.. we don't, it's impossible fr us to be 100% cetrain of the true facts and as such we shouldn't be reparing them.

If a garage repaired one of these tyres and the car was then involved in a serious accident caused by tyre failure who would the courts hold responsible? The tyre is clearly marked that it must not be repaired after "runflat operation".. a condition that is more often than not impossible to detect on "runflat" tyres and no doubt the tyre manufacturer would blame the repairer so as to avoid a law suit.

These repairs...

Only a special vulcanised plug patch should be used which repairs the tyre to the required standard, all temporary plug type repairs are illegal in the UK as far as I know... so this would rule out the Dynaplug solution.

As for the instant sealer gels etc.. as per the quote above..

It is claimed by some that sealants used from new can have the effect of masking, by sealing, a puncture in a tyre that may have caused damage that, were it noticed, would render the tyre unfit for further use.

..This means that you could pick up a nail.. lets say it's close to the sidewall, but not that it matters... and the sealant instantly repairs it, there you are happily driving down the motorway at 70MPH completely unaware that your tyre could explode at any moment. The same thing would apply if you added the sealant yourself to get you home.. what if you forget to get the tyre repaired properly?.. you will drive down the motorway at 70MPH.... blah blah BANG!

I wouldn't recomend ANY of this stuff to anyone, nothing is better than a spare wheel to put on in the event of a puncture.. no matter how minor it appears to you, if you haven't got a spare wheel.. buy one.. it could save your life.

That is a very useful and interesting response, thanks very much.

I still would like the DynaPlug system with me as an emergency repair just to get me back to the tyre depot that can replace a Bridgestone R F tyre, I would certainly have a RFT removed for inspection after having a punture to check if it needed, as I would expect, replacement.

Using the repair plug might stop the runflat ring actually being in contact with the deflated tyre for a long period so that might not also need replacing.

I quite accept that if some one was cutting corners and trying to keep costs down it would be very foolish and dangerous not to have a deflated RFT inspected without delay.

Over past years I have had two motorway blow outs at high speed and they were not very pleasant and should be avoided!!

But they not Rav's.
