Run Flat Tyres-Some Experts Warn Of Down Sides – CBS Local

run flat tyres

Run-flat tires are now standard on dozens of cars, but some experts say they aren’t right for most drivers.

Almost all the major tyre companies now make run flat tyres but i now know from my own experience that drivers, are not that happy with the concept and see the fact that they always require a new tyre, when they have a puncture a little daunting.

Some drivers mainly the older drivers dont like the idea of not having a “proper” spare wheel, and we have indeed had many requests for people wanting to purchase a new wheel and tyre to keep as a spare.

Run flat tyres have been around for a while now?

Run flat tyres are nothing new, but not all motorists accept them? We have customers complaining on a weekly basis at my tyre depot here in Halifax Yorkshire. I must admit that it is mainly the older driver that can’t accept them and has a little moan.

One of the problems is the cost, and the fact that the tyre requires replacing every time that it has a puncture. Because you have to drive on them when it is deflated, then  new run flat tyres  are  inevitable, when you finally have it fixed.

Some customers go to the trouble of sourcing out a new wheel and tyre for the spare, and I must admit that you can’t blame them. One guy has just done that with his Nissan Juke. He was travelling to France and could not bear the thought of not having a spare wheel. Tyres on the continent cost almost twice as much as they do in the UK, but it was the big gaps between services, that put him off travelling without a spare.

Run flat tyres operate with the TPMS system

On the other hand some customers have no problem with run flat tyres; they see it as a safety feature, which is what it really is. The Wireless Tyre Pressure Monitoring System will pick up any loss of pressure from your run flat tyres. This is a sign to slow down to 50MPH for 50 mile until the problem is looked at by your local tyre centre.

Will Run Flat Tyres Repair

There was a time when we used to repair them but the problem is that you do not know how much damage has been caused to the tyres internal structure. It is virtually impossible to tell by just looking and so a replacement Cheap Run Flats are the best option and we no longer offer to repair them.

I can understand why some people just do not like the run flat but I am sure that it may have saved many lives. When the tyre deflates rapidly, it does not deviate out of its lane and therefore is not a danger to other traffic thus avoiding a crash. To me that safety feature plus a spare wheel would be the perfect scenario?

Pirelli Run Flat Tyres Can We Repair Them?

When the run flat tyre first came on to the market

I was not so sure what to think? The tyres were developed together with the car manufacturers and were developed to specifically fit the cars on which they were to be fitted.

The whole concept surrounding these tyres is based on safety, both for their car and more importantly the driver. Another factor was that these cars could do without a spare wheel, thus reducing the weight of the car. This has contributed to the “green” credentials of the cars that they were fitted to.

Tyre Pressure Monitoring Systems (TPMS) have to be used with run flat tyres

Pirelli Run Flat tyres were specifically developed to be based on the specifications of the cars on which they are to be fitted. This means that, Run Flat tyres may only be mounted on vehicles that are specifically made to have the Run Flat tyres. This was one of my first bones of contention, when my young apprentice tyre fitter snapped the TPMS valve where it was located on the inside of the wheel where the  normal tubeless valve would normally be fitted. (cost me £80 to replace)

I also had purchase one of the new style tyre fitting machines, because of the difficulties that we encountered when trying to remove and re-fit the tyre from the wheel. The new type machines were equipped with special tyre hold down tools that held the tyre in place so that the fitter could use both hands when removing and fitting these difficult  tyres. After a while we were used to fitting these tyres and also learned about the TPMS systems that accompanied these tyres fitted to the car.

The Pirelli P7 Cinturato run flat tyres was also developed as a more environmentally product, because Pirelli had also taken the time to not only make the tyre into a run flat ,but also make the tyre into a high performance design tyre with lower fuel consumption and reduced road noise. They were also able to use a more eco-friendly compound to the tread area, giving this tyre more stability in the footprint area. The development of this tyre brought together many improvements making it a highly safe product that would complement medium and high powered vehicle such as the BMW range including the BMW Mini models.

When a loss of pressure arises in a run flat tyre then you must only continue at 50mph

The high volume of cars that are now fitted with the run flats, have helped me in thinking that these tyres have become a success story. At first I wasn’t sure I thought that they were just a passing fad that would go as quickly as the appeared. But I was wrong, because I have listened to some of the stories from my customers, of how they prevented them from having an

accident and also of how they were able to carry on with their journey. The truth is that if your tyre suddenly loses pressure when you are doing 70mph, on a busy motorway, then you will have a better chance of getting out of a sticky situation, than you would have with normal radial tyres.

Your car will remain stable and not deviate and possibly cause a crash in busy traffic, as happened to a friend of mine recently. His tyre blew out and he hit the central reservation causing the car to swerve and have an accident. Although he was badly injured he is now fully recovered, but I am sure that of he had run flats fitted to his car then the car would have kept the line and not crashed  into the barrier, throwing it into the path of the traffic in the other lane.

Also if you do lose tyre pressure and it will tell you on your TPMS instrument on the dash of your car, then you must only drive at 50mph. At 50mph you can drive the car 50 miles , this is usually enough distance to enable the driver to reach the safety of a garage or the nearest tyre centre and have the tyre attended to.

Pirelli recommend that we should not repair run flat tyres

As the heading suggests Pirelli is one of the manufacturers that do not recommend that we repair run flat tyres. We at Pellon Tyres here in Halifax have been known to repair these tyres but only if knew that there was a screw in the tyre and the tyre had not deflated and the TPMS light had not come on. We have since stopped this procedure altogether now and only fit a new tyre, because we just do not know what damage was done, when the tyre was de-flatted.

This reminds me of a recent case in mind. One of our lady driver customers who owns a very nice BMW, had noticed her TPMS light was warning her of a problem with her near side front tyre, which had a pressure loss. The BMW was fitted with Pirelli tyre as original equipment size 225/45×18 P7 Cinturato.

She was heading from the M62 motorway, back to Halifax when the incident happened and was not too sure what the light coming on meant. She carried on driving and then decided to pull in and give us a ring for advice. Because the car was fitted with a TPMS system we knew that the car would be on run flat tyres and so we recommended that she drove the car carefully to our depot in Halifax, a distance of about 5 miles well within the 50 mile recommended by Pirelli.

When she arrived, the inside of the side wall of the tyre was completely coming away and so we had to fit the lady a new tyre. The customer worked in a high up position for the local  run flat tyrescouncil, but because we had a tyre in stock she was able to attend her meeting. If she had normal radial tyres fitted then she would have been delayed until someone came out to change her wheel, so everybody was happy…more reading… http://www.pirelli.com/tyres/en-gb/car/find-your-tyres/all-about-tyres/technology-runflat

Mini Run Flat Tyres-Definitly an Improvement to road safety- KULR-TV

Angie’s List: Mini Run Flat Tyres

Many new models are now equipped with inflator and sealant kits or run flat tires which are designed to go at slower speeds for 50 miles or more after a tire has been punctured.

 

eric roberts‘s insight:

Mini Run Flat tyres are an interesting subject.

The problem in my eyes is that cars were getting bigger and faster, and at the same time the car makers were being pressured by governments to make their cars more fuel efficient and greener.

This meant shedding weight and creating engines that were controlled by computers to really hammer down the emissions caused by burning fossil fuels (gasoline or petrol in the

How run flat tyres work

UK). The car companies looked at all sorts of ways to reduce the weight and even the tyre companies looked for ways of making tyres lighter in weight, and indeed they succeed.

BMW come up with the Mini Run Flat Tyres

They also came up with the Mini Run Flat Tyres. This would mean that cars would no longer have a spare, because when the tyre on a car had a sudden drop in pressure (puncture) then the car could drive on, albeit at a slower speed (50 mph) until the tyre was changed. The positives are that the car would not deviate and carry on driving in the normal way and therefor not causing an accident and much safer than a standard radial tyre, also you would not have to get out of the car on a rainy night to change the wheel when you had a puncture.

The drawbacks are the cost of replacing these tyres is much higher than a standard tyre, A new Mini Run Flat Tyres is required after each incident, and on long journeys should you have the need to want a new tyre, then you only have fifty miles to have the Mini Run Flat Tyres fixed. Many tyre companies no longer repair Mini Run Flat Tyres.

In the States the gap between some towns and cities can be hundreds of miles. So you pays your money and takes your choice ?

Run-Flat tyres from Bridgestone Tyres

 

When I first heard about the run-flat tyres concept,

I was a little bit sceptical, about how they would work say when the car was driven at eighty miles per hour on a wet busy motorway. However as time has gone on I have got used to the

Run-Flat tyres

How a Run-Flat tyre works

the idea of your car not having a spare wheel and also the fact that the car does not swerve or deviate as the tyre is deflated at speed.

Now run-flat tyres are just part of the tyre scene and our customers just accept the fact that if one goes flat and they have to drive home on it, then they are going to need a new tyre at some stage in the future. I am a great advocate of road safety and the fact that tyres play a great part in the tyre safety picture. Run-flat tyres are now part of that picture along with all the other safety features that are being produced by innovative tyre companies at the moment, such as “self-seal” technology that is made by Continental tyres, Pirelli tyres and Kumho tyres.

The fact is that run-flat tyres are now being fitted to many cars from new now and one of the leading makers of Run Flat Tyres  are the giant number one tyre company of the World, Bridgestone tyres. One of the growth markets for run-flat tyres is the larger and heavier premium cars such as Mercedes and BMW Run Flat Tyres Prices, who have in fact worked side by side with Bridgestone to help develop this concept of tyre that is safe to the driver and also to other road users, should a tyre run over an object on the road and be subjected to a sudden pressure loss.

If run-flat tyres are subject to a sudden pressure loss then the car will keep driving in a straight line and the car can continue on its way, without any mishandling or deviation that could cause any problems to the other drivers in the same vicinity. A normal car tyre that is subject to an instant loss of pressure would probably disintegrate at speed and because the car to deviate badly, this is, in fact, the cause of many car crashes, this could result in the car colliding with several other cars causing a very bad accident.

Another good point to remember is that there is no need to have to pull onto the shoulder and change your spare wheel? You can drive the car, to your nearest tyre centre. If you are a stranger to the area then I would suggest that you look up your nearest Point-S tyre centre. These centres are dotted all over the UK and are vetted for a fair price and give excellent

service. Point-S can be found online at www.point-s.co.uk and if you like you can even check out the price on the website, to see what a great deal you can get.

A slight drawback with run-flat tyres is

That once you have detected that the tyre is no longer inflated, then you are restricted to driving at 50mph at a distance of 50 miles, but this can give most people ample time to get to the nearest town and have the tyre changed. Also for the old-fashioned amongst you then the cars with run-flats, do not have a spare, this was

originally to give the cars more space where the spare tyre would normally be sitting, also it lightens the weight of the car to help conform with emission controls.

Also, BMW Run Flat Tires Problems now run alongside with the TPMS systems (Tyre Pressure Monitoring Systems). This warns the driver if the tyres are losing any pressure, or in fact if the tyres have suffered from an instant loss of air. The warning light will illuminate and warn the driver that they have a problem with a tyre. This is a great all round system and is a great safety feature in many new models of cars that are now entering the marketplace, including the SUV models.

Other tyre companies also make the run-flat tyre and I believe that a budget tyre is available made by economy tyre company Wanli. Most of the leading tyre companies now make run-flat tyres and there is now a large choice available.
