Toyo - World beating tyres from a World leading company.

Toyo are uncompromising in their pursuit of excellence. That is why Toyo is one of the world's leading tyre producers, selling products in over 80 countries. So when you buy a Toyo tyre, you do so with the utmost confidence that you're buying the best.
 
Each year, the Japanese parent, Toyo Tyre and Rubber Company, invests around £57 million in research and development and they only use the very latest tyre design, engineering and technology. They've even developed their own dedicated and highly sophisticated, design software, Dynamic Simulation Optimised Contact II, or DSOC II. This allows them to create advanced tyre designs in virtual reality, which speeds up the development process and produces tyres that are both dynamically brilliant and easy on the pocket.

Their aim is to produce high quality tyres that offer outstanding roadholding in the dry or wet, feel secure and stable in all conditions and at all speeds, make the minimum amount of noise and give you the maximum amount of life; the perfect tyre.
  
With a choice of  tyre types and a huge range of sizes to choose from, there's a Toyo tyre to suit all vehicles. Whatever you drive, wherever you drive and however you drive, it's reassuring to know that the tyres you're driving on are backed by the vast resources, experience and expertise of Toyo.
 

Tyre Pressures
Probably the most important thing to check regularly, making sure they are the same as the manufacturers recommendations.

An under inflated tyre can overheat, wear out the shoulders of the tread quickly, puncture easily and give a poor handling car, with slow and heavy steering. An over inflated tyre wears the tread centre faster, can overheat and makes the steering feel light and vague, again giving a poor handling car.

Tyre pressures should be checked when cold and kept to the recommended pressures. We have a large range of tyre pressure gauges, compressors and a tyre pressure monitoring system, so there's no excuse for not checking them regularly ! The most cost effective way to start improving your cars handling.

Speed Rating
All tyres carry a speed symbol in the form of a letter indicating the maximum speed for which the tyre is intended. Below is a speed rating table that shows the maximum speed a tyre is tested to and its corresponding Speed Symbol. These are tested speeds, not recommended speeds. It should be noted that speed ratings only apply to tyres that have not been damaged, altered, under-inflated or overloaded. Most tyre manufacturers state that if the tyre has been cut, punctured or has sustained other damage then it no longer retains the tyre manufacturer's original speed rating, even after being repaired.

When purchasing tyres you should only consider a tyre that has at least the same speed rating, or higher, and never replace with a tyre of a lower speed rating, even if you drive at low speeds. There are other factors other than just speed that determine these ratings, so changing to an inferior rated tyre could prove to be dangerous and a risk to safety. However, it is ok to fit tyres with a higher speed rating than recommended. Do not mix tyres with different speed ratings - if replacing in pairs then the new tyres should be the same rating as the tyres fitted on the car.

On a 195/50 R15 89H tyre, the Speed Rating is H and using the table below shows that it has a Speed Rating of up to 130mph.

Load Index
The tyre Load Index is the number after the tyre size, written before the speed rating, and is a numerical value used to compare relative load carrying capabilities.

On a 195/50 R15 89H tyre, it is the 89 number in the description, and using the table below shows that the tyre has an ability to carry 580kg's at the tested speed rating figure.

The higher the tyre's load index number, the greater load capacity it has. Tyres should only be replaced with a Load Index of the same or above that recommended and fitted originally.

The load indexes of the tyres used on road cars and other vehicles typically range from 70 to 110.
