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.
