Performance Car Tyres? are they any Different to the Rest?

So as you can see Michelin Performance Car Tyres have a tyre specific to Mercedes cars with a sidewall marking of MO. This car should be replaced with the exact same tyre (Are they different)

Performance Car Tyres are becoming a category on their own. The reason I say this is because more and more of the top tyre manufacturers are teaming up with the car producers, to develop a tyre that is specific to that car. These tyres have even got markings that specify which car the tyre should fit. Here is a example list of the current tyre markings courtesy of Michelin Tyres UK.

E.g. MICHELIN Primacy HP MO      MO is a Mercedes specific marking
E.g. MICHELIN Pilot Sport PS2 N3  N is a Porsche specific marking
E.g. MICHELIN TM ENERGY Saver *        * (star) is a BMW specific marking

So as you can see Michelin Performance Car Tyres have a tyre specific to Mercedes cars with a sidewall marking of MO. This car should be replaced with the exact same tyre as the one that comes off, and it is important that the drivers of these performance cars are aware of this.

The tyres are designed around the characteristics of certain cars and the tyres will complement the cars attributes. For instance performance cars are usually heavy vehicles that can

accelerate and in general go very fast. The Performance Car Tyres on these cars have usually been developed with a softer compound that your standard road use. The tyres are also lighter in weight and this combined with alloy wheels, help make the car more fuel efficient.Performance Car Tyres

If you are the owner of this type of car you should be aware that these Performance Car Tyres do have a part to play in the general performance and handling of your car, so when you are buying your tyres make sure that you are buying tyres that are like for like. The tyre manufacturer will have other tyres in their range that are just the same size and name, but they do not have the car makers sidewall marking on them and so are not the same tyre.

Tyres for performance cars are made to help the car perform better on cornering and steering,

also aiding the cars noise levels on different road surfaces. Other leading brands of tyres that make tyres for performance cars are include Pirelli, Continental and Yokohama tyres, so drivers have a good choice of brands on the replacement market.

Peugeot 206 Estate Clutch

Clutch Vibration Problem-TOYOTA AURIS TD comes in with a Clutch Vibration Problem

Clutch Vibration Problem

TOYOTA AURIS TD comes in for a Clutch Vibration Problem

For some unknown reason.  Christmas time brings in a few cars that are having Clutch Vibration problems. Hence, these are the normal problems. So, such as the driver cannot get the gears. Or the gears grind. Thus, when trying to drive the car and so on.

The Toyota Auris was a slightly different problem. As a result, the car was sort of vibrating and rattling. Consequently, as it was been driven along. When speaking to the customer. Ryan Linton my workshop manager. Discovered that the car had only had a new clutch fitted about two years ago. So the customer found it highly unlikely. Hence, that the clutch could be causing the vibrations. Especially, when driving the car along.

Ryan explained that the only way to tell is to check the clutch for the Clutch Vibration , by stripping the housing off and taking a look. The customer agreed and he took one of our courtesy cars while we explored his car to see what the problem was.

The other clutches that were done this week were standard sort of jobs, taking two or three hours to do, but we always check with our Auto-data computer system, for the times it takes to do these jobs and this Toyota was shown to take seven hours, this included the Duel mass Flywheel having to be changed, but at this stage we did not exactly know what was wrong with the car.

Clutch Vibration Problem

Ryan  stripped down the Auris clutch housing and assembly and found that the system was a Duel Mass Flywheel  for short and that the car had only had the clutch fitted two years ago and nothing had been done to the Dual Mass Flywheel. This action had

caused the pressure plate and the Dual Mass Flywheel to wear prematurely and caused the DMF to have more play in it and therefore cause the Clutch Vibration.

We did not fit the other clutch, but the customer said that he would not go back there again. The cost was estimated at about the £1000.00 mark and the customer gave us the go ahead to do the job. The time given by Auto-Data was pretty accurate and it took Ryan near enough six hours to complete the job. We always fit LUK clutches and DMFs because they were the company who originally developed the products along with BMW in Germany and to date we have never had any warranty problems with the LUK products in the past.

The Toyota Auris clutch and DMF was finished, tested and returned to a happy customer another job well done by my excellent staff.

eric roberts‘s insight:

Lead acid batteries have now been around in their present form for many years.

Of course, it is only in recent times that the lead acid car battery has been overcome. Subsequently, by the more modern technology batteries . As a result, that are now being developed for the modern electric and hybrid car manufacturers. Significantly, due to the rush for a more environmentally friendly battery products. Such as the Lithium-Ion ! Now used many car models such as the Nissan leaf and the Toyota Auris hybrids.

In my opinion though, the ever faithful lead acid batteries, that we still use in the millions. Thus, will still be around for many years to come. They have been tried and tested and proven for almost a hundred years since their invention in 1859 by French physicist Gaston Planté.

Nothing much has changed in the past forty years of time

As an old guy then, I have bought and sold batteries now for more than 40 years. Car battery types have had modifications. Additionally, such as different lead alloys. That are now used in the manufacture of the battery plates. Increasing development of casings to help suppress and resist vibrations. Most truck and car ones are now sealed and maintenance free. So the motorists do not have to top them up any more. Although some battery makers have the old fashioned screw tops. So that you can top up the electrolyte when the acid  has evaporated.

The big development came when the AGM lead-acid batteries was invented in 1985 for military use and was developed by Concorde batteries for commercial use outside the military. The AGM (absorbed Glass Matting) lead-acid batteries is completely sealed and now used in hundreds of applications, although once again these batteries may be slowly replaced by the Lithium-Ion batteries. I know that some golf trolley ones are coming out in Lithium-Ion, but at the moment they are very expensive and golfers have a reputation of shall we say, “not putting their hands in their pockets”. The Lithium-Ion’s  were also developed for the military and used on the stealth bombers and they were also used in space flight and on the Mars Lander Craft “Curiosity”.

Another recent development of the lead-acid batteries

So a new introduction has been the introduction of “stop Start” technology. Used on some new models of cars. This was developed by the World’s leading battery company, Johnson Controls. The trade name that they use for these batteries is Varta batteries. What happens is when the car stops the engine is switched off and

Micro hybrid battery similar to the one used in the Mars lander

when the car wants to set off again the accelerator is pressed and the car restarts. The batteries for this job have to be more powerful that the standard lead acid battery and so the AGM battery lead-acid batteries are used.

In my opinion the lead acid battery will be further developed and used on other applications that have not been invented yet, and will still be a player in the crazy mixes of the development of the modern car, their big advantage is that they are almost 100% recyclable, which is more than can be said about the lithium-Ion batteries.
