Adams and Page are one of the largest stockists of yokohama tyres in the country.We have been a leading supplier of yokohama for over ten years now, and we travel regularly throughout England and the continent providing race support for competitors wishing to get the best out of their tyres. Les Adams first started racing an Austin Healey 3000 in 1960, our knowledge and expertise is based on 50 years racing experience.
We have supported the Classic Sports Car Club since it was formed 8 years ago, and in 2011 will attend every one of their race meetings in the UK and their race meeting at SPA Francochamps in June. These are the most popular tyre for circuit racer, used by club and professional competitor alike. Lotus on Track Elise Trophy use them as a control tyre and are now chosen by Lotus Cup UK for their endurance race series, we supported the first 1000kms race at Brands Hatch in November 2010 where the tyres performed extremely well.
The Yokohama A048 Tyre has a stiffened carcass, which combined with the tread pattern and compound makes it one of the best road legal race tyres in the market today. It is listed in the MSA blue book as a 1b tyre.
The operating temperature for the tyre tread compound is between 45C and 120C. The optimum temperature is 65-95C. When using a pyrometer, and measuring the temperature of the tyre, start by taking the hardest worked tyre first and the inside measurement first. (The inside edge of the tyre should be the most worked, so it is important to get an accurate reading to make sure that the tyre is operating within its parameters).
Temperatures across the tread ideally should vary by no more than 15C from inside to outside when possible.
Basic guideline settings are given below;
For “M” compound tyres maximum hot tyre pressures should be between 28 and 32 psi.
For “MH” compound tyres maximum tyre pressures should be between 28 and 36 psi.
These are guide line settings only, and can vary for different weight cars.
A 450kg Caterham will have different settings to that of a Jaguar weighing 1000 kilos more. If in doubt please ask.
Although the tyre will work with camber angles of up to 5 degrees negative, the optimum camber angle is 1-2.5 negative if springs and roll stiffness are correct.
The 048 is available in the following sizes.
