Years ago when run flat tyres were introduced they seemed like a great idea but drivers were then told that they couldn’t mix up run flats with conventional tyres and you couldn’t get a puncture repaired. Once the tyre had been punctures, whilst the run flat would get you home the bad news was that you then needed to replace the tyre. However, I have found out that this isn’t necessarily the case. It was highlighted recently when a lady driver managed to get a nail in her run flat tyre fitted to a Read more »

The Graham Hill gadget of the week is a tyre pressure warning system. I’ve reported on many occasions the importance of running tyres at the correct pressure. Not only is it a legal requirement punishable by points and a fine, tyres wear quicker, grip is reduced and fuel consumption can increase by up to 10%. We all know that we should check our tyres daily and at worst fortnightly (as suggested by tyre Read more »

Another report I mentioned earlier this year spoke about the likely move by drivers to winter or cold weather tyres following the severe weather last winter. Well the move has already started according to ATS Euromaster. No I don’t mean drivers are already fitting winter tyres in the middle of the summer. Orders are already being placed by ATS for winter tyres to the tune of £3 million. They already have forward Read more »

New tyres must meet European standards for safety and a raft of other basic regulations covering grip, economy, speed etc. British standards cover re-treads and remoulds as well as puncture repairs so many motorists look to replace their current tyres with the cheapest they can find, believing that all tyres that are sold meet basic standards and that the standards mean that whilst the cheepo tyres might not last quite Read more »

It’s gadget time again! Just as I was adjusting myself to touch screen technology in cars with the new touch screens able to control the sat nav, heating system, on board computer and stereo I’m told it is now old hat! The new technology about to be introduced is hover technology whereby you simply hover your finger over the key you would have previously touched on the screen and the screen senses it Read more »

One of the biggest confusions over end of lease charges is that of scuffed alloy wheels with bills for repairs being as high as £120 per wheel. Many drivers cannot understand why scuffs to alloy wheels are chargeable as damage. As one woman that wrote to me explained ‘We all scrape wheels on the pavement when parking, surely it is no different to worn carpets, and stone chips?’ The fact is that if you are driving Read more »

Recent discussions regarding the use of winter tyres in the UK following our harsh winter has spurred on many to provide more advice suggesting that winter tyres may not be necessary if drivers simply treated tyres with a little more respect. Simple maintenance such as the regular checking of pressures would be a start. The National Tyre Distributors Association have followed up with the following points when replacing tyres:
- Tyre size markings across an axle must be identical.
- Â Tyre construction across an axle must be the same
- The load index must be equal or be higher than the manufacturer approved tyre for the vehicle
- It is recommended that the speed rating is either equal or greater than the original approved tyre.
- Mud and snow – winter tyres should ideally be fitted in complete sets and should not be mixed with other tyre types across an axle.
- It is recommended that when fitting two new tyres, they are fitted to the rear axle unless rear tyres are a different size to the fronts or the vehicle manufacturer’s handbook states otherwise.
- There may be special dimensional requirements preventing the mixing of tyres such as 4WD vehicles.Â
I know I have provided this information before but do you know what the markings mean on a tyre? Lets take a tyre that reads 195/65 R 15 91 H. Here’s what the markings mean:Â
195Â : The width of the tyre in mm, also called the section width.
65Â : The aspect ratio is the ratio between the sidewall height (side of the tyre) and the width of the tyre. It is expressed as a percentage.
RÂ : The type of construction (R for radial).
15Â : The internal diameter of the rim in inches.
91 : A tyre’s load rating is identified by a number and corresponds to the maximum load the tyre can withstand at maximum pressure.
H : Speed rating (also known as Performance Index). Indicates the maximum speed at which the tyre can bear a load corresponding to its load ratingÂ

After Christmas we are now about to hit the highest drink drive season. Long warm evenings beckon and the incidence of drink driving increases but where in the country are you most likely to be tested, where are most of the drunks driving around in their cars and where are the least offenders? I have the answer from the Home Office. You are most likely to be tested in Wales, most offenders are caught in Cheshire Read more »

Considering the particularly bad winter that we suffered there are suggestions that we should follow other European countries and introduce winter tyres. Whilst not wishing to go the compulsory route it has been suggested that we should adopt the Dutch system of making winter tyres widely available. After making the tyres available about 10 years ago it is understood that about 50% of drivers switch each winter. Read more »
