Ever wondered what tyre pressures to use at the race track? You're not alone.

One of the most common questions at amateur track days is "what tyre pressures should I run?" Most drivers don't answer this question confidently because it's a bit of a black art.



If the driver of this Improved Production Racing Association Holden Commodore SS VN Group A wandered up to me and asked "what tyre pressures should I be running" I'd suggest that the manufacturer's recommended pressure for the ADVAN A050 tyre (not the car) is around 30- 32 psi hot. But it's a big, heavy and powerful car....



If the driver of this 1960s mini (I'm guessing the age) came up and asked "what tyre pressures should I use?" I'd say the manufacturer's recommended pressure for the old ADVAN A032R tyre (not the car) is around 32 -34 psi hot. But it's a small, light and not very powerful car...

If the mini was using ADVAN A050 tyres the recommended pressure would be the same as the Group A Commodore, 30 - 32 psi hot. Don't believe it? Neither did I at first. They're completely different cars. This was first explained to me by the Yokohama motorsport tyre fitter at a Yokohama V8 racing ute round in Darwin. It took at least four beers for this sink in.



After a decade of working for Yokohama and racing my own VW beetle and Subaru WRX I decided to pass on some knowledge. In the last 12 months I've attended Circuit Club and ADVAN track days armed with a pressure gauge and pyrometer to help participants get the most out of the Yokohama tyres.
