 The objective of this site is to provide an un-biased reference for tyre users and tyre sellers to establish reasons for tyre damage, manufacturing defects and unusual wear.

This will, hopefully, eliminate or reduce the incidence of unnecesary or un-warranted claims and minimise the ill-feeling that is often caused between the end user and the tyre industry.

All the examples of damaged and worn tyres on this site have been carefully examined and researched and the conclusions are generally accepted across the industry. However, input and advice from suitably quallified experts in the tyre industry will be most welcome.

There are many instances where a certain type of incident may occur in varying degrees of intensity and we have endeavoured to show all the variations wherever possible. New and interesting variations will be added as they are received.


The site has been arranged into different sections which relate to the various areas on a tyre. It will be noted that the section "Refer to Manufacturer" is very small. This is because very few tyre problems can be attributed to poor manufacturing quality. A figure of .0001% of factory defective tyres reaching the end-user is not unusual in the industry.   












Who makes the best tyres?

When one considers the large variety of sizes and applications major tyre manufacturers need to produce, it is easy to see that for one manufacturer to be able to consistently produce better tyres than anyone else is impossible. No manufacturer would seriously claim to be “the best” across all sizes and applications at one time.

Generally, there is little to choose between the major tyre producers. There is no tyre on the market that consistently achieves superior mileage (or any other characteristic for that matter).

Motorists are inclined to form subjective opinions about their tyres. A customer once claimed that he would never consider a specific brand because, “thirty years ago, my father and I were on a trip and we had a ‘blowout’ with one of them. They wouldn’t give us a new tyre so we’ve never used that brand since!”
The damage he went on to explain sounded very much like a casing dislocation due to pressure-loss, in other words - “run-flat”, which, under similar circumstances, would have happened to any tyre!

There are many similar stories of motorists reaching unfair, un-informed and subjective conclusions. The poor perception of the specific manufacturer is compounded when claims are refused, usually accompanied by a technical report that few people understand.

The answer to the “who makes the best tyres” question can be answered in this way:  For a particular vehicle, application and driver, there probably is a tyre that will perform better than another and the only person who can help you make that selection is the tyre dealer.

That raises the question, which is: will the dealer’s recommendation suit you, or his profit margin?

The best advice is to find a reliable, honest tyre dealer and go along with their recommendations – there are not too many poor tyres out there. The most important thing to do is to look after your tyres, rotate them and check your inflation pressures regularly.

This site will help us look at the way tyres wear and also the most common types of damage that can occur, regardless of who the manufacturer is.
