Tyres and Pressure
Discussion
Hi,
The correct pressures according to the Steve Heath manual is 24 rear and 22 front. I was running those pressures until this weekend when I checked the pressures and my brain malfunctioned. I couldn't remember if it was supposed to be 24/26 front/rear or the other way round so I decided to play safe (the sun was out and I wanted to get going)and go with 25psi front and rear. I have to say that it was much better and more confidence inspiring on the corners and belting it from the line felt less squirmy. Oh, and I'm running Pirelli 6000s which have been slated by pretty much everyone on here.
Best thing is to experiment and see what works. Start low and you'll feel the tyres squirm and roll on corners.
Can't comment on the Toyos though.

Hi Gary
It might be a good idea to check the age of the tyres by using the dot code on the side wall and it will be branded into the side of every tyre (only on one side though) the four digits will tell you exactly when a tyre has been manufactured,e.g. 4705 - this means the tyre was made in the 47th week of 2005. Make sure this isn't more than five years old in reality. However the DOT code on the tyre could include a < (triangle thing) and three digits if so it means the tyres were ptoduced between 1990 and 1999, the first two digits the week number and the last the year eg 039 means week 3 1999, if it were 030 then week three 1990 on so on, if there only three digits and no < that means 1980 to 1989. The four digit code only applies to 2000 and on.
I did this and found my tyres were 9 years old and needed to be replaced did a bit of research using tyretest.com and have found the following, the lower the reading the better
The bridgestone was the clear winner and I bought a set and am very pleased, tyre pressures 24 rear and 22 front
