Markings Explained

At first glance the lettering on the side of the tyre may look complicated. It is not meant to be that way. The lettering explains the exact specification of the tyre you have. In short it tells you anything that you may need to know about your tyre.

But on our website we have what everything means!

Tubeless Tyre Valves

The little rubber and brass valve that holds the air in your tyre, and admits new air, is one of the world’s most successful inventions. William Schraeder designed its fundamentals nearly 120 years ago.

The little “springy thingy”, called the “valve core”, that screws into the brass valve really hasn’t altered all that much in that time, and all you need to remove it and let the air out, is a slotted valve cap. Or you can just depress the little button in the centre and you get the same effect, only slower.

Yet when you buy a new tyre, the fitter always replaces the valve. Why does he bother?

The modern tubeless snap-in valve is compressed into a hole in the rim to provide a seal. A brass stem is adhered to a rubber skin, with a domed shape on the inside of the wheel to prevent it being blown through the hole by the air pressure.

Over time, the degree of compression is lowered (it doesn’t fit as tightly). It may even crack around the groove in the rubber which lodges in the rim hole due to flexing.

The valve actually flexes as the wheel revolves, particularly if it is a long one designed to protrude past the wheel trim. Ultra-high-speed photographs have shown the valve actually touching the rim at right angles at very high speeds. Also the heat during service causes the bond of the brass to the rubber to deteriorate, and if this bond ruptures, the stem blows out, and the tyre goes down quickly.

So reliability is what it’s all about. It’s much better in the long run to replace it after one tyre life.

You can contribute by using dust caps or valve caps, and giving a blast of air around the valve before you clamp on the air chuck, which you should do monthly. If you suspect a leaking valve, a “dob of spittle” on the end of your finger into the brass stem is the tried and true method. If it bubbles, first check the valve core is tight. If it is, loosen it, let some air our, then retighten to dislodge any dirt that might be there.

If it still leaks, replace the core. Unscrewing the core right out will let all the air out, and coincidentally clean the seat that the “springy thingy” seals on. To do this, you need a slotted metal valve cap, or a valve tool, and a kindly service station operator to assist if needed.

The metal clamp-in valves are different. These are used in some alloy wheels, where the thickness of the metal around the hole is too great for a snap-in type. But they are even more desirable when high speeds are the norm. Unlike a snap-in, they do not flex, and they sandwich two air seal washers under compression to get the air seal. So even though they cost more, they last longer, because it is not as necessary to replace them after every tyre life.

Pirelli & Red Bull.

Pirelli UK have a groundbreaking three-year sponsorship and full hold up partnership with popular and innovative MX series, the Red Bull Pro Nationals.

Pirelli are going to have a main support programme for the series with a devoted tyre supply and changing vehicle to cater for all riders at the events. Pirelli were fascinated by the series for its professional organisation, good crowds and the large volume of competitors through clubman, youth and elite riders.

Pirelli staff will be on hand at every round to fit tyres and inform competitors on fitment, type and pressures, as long as a truly unique race service. The brand is also very involved in getting rider feedback, which will in the end help future product development.

Illegal tyre fires cost £300k

The fire service have been left with more than £300,000 to pay after 2 fires that involved illegal tyres being stored in Londonderry in 2009.

Nearly 100 firefighters were involved in just one of the operations in October at Campsie. That operation alone cost over £229,000 and it later emerged that those tyres had been stored there illegally.

In August 2009, there was a fire in Pennyburn at a tyre depot and it cost £106,000 to be put out. There were 4 fire pumps ands a foam tender that were used during the operation.

People who cold screen their way to work.

On a frosty morning 1 in 3 motorists drive off without actually being able to see out of their window screen because he or she has failed to clear the ice and snow off of it.

A survey has shown that in their hurry, most accidents happen near the home and it also shows that not every body puts their seatbelt on. Because people are not letting their car warm up they are simply choosing to hurry and hoping they can see through a tiny gap.

The survey was carried out by continental tyres and it shows that most motorists were in too much of a hurry to fully defrost their windows before heading off to work. And me were more guilty of it than woman.

The company Continental asked 4,000 drivers in Ireland and the UK, and more than 10% of people had had a near miss within the last 12 months because of an unclear window screen.

General manager Paddy Murphy said: “Preparation is key when setting out in your car. It is essential to be able to see and to be seen. An astonishing 52pc of people know it is wrong to drive without a fully clear windscreen but fail to do anything about it.”

Always check the following things when driving in the icy weather.

● 70pc never check tyre tread depth and fail to make sure tyres are roadworthy.

● 25pc don’t check to see if their lights are working.

● One in four drivers admit they are not fully awake when they get behind the wheel, and that it takes them at least four minutes of driving time to wake up properly

Roads despair over state of repair

Freezing conditions are making things difficult for drivers across the UK – but the continual freezing weather means potholes are set to pose an equal and long-lasting hazard.

On Monday (4 January 2010), the AA had its busiest day ever – recording 25,000 breakdowns across the country. It says that there are a third more potholes right now than is usual – and that they’re potentially more unsafe to your car as well.

The AA’s President, Edmund King, said: “Pothole season is usually at the beginning of Spring. What’s different this year is that the cold snap has come so early, which is leaving roads crumbling a good month and a half earlier than normal.

“We are seeing more trench-like potholes where utility firm have filled in a surface after working on it, but not particularly well. This creates larger holes which can cause immense damage, particularly if you’ve got low-profile tyres or large alloy wheels.”
