Still relatively inexperienced but...

Are his times up and down day to day, session to session or lap to lap? If lap to lap, are his times faster at the start or end of the session or generally up and down throughout? How close is he to the quick guys? Is he as quick as the front runners in the first few laps?

All the above help determine the starting point for tyre pressures within the general operating range of the tyres for your class. However, the overiding factors are tyres used, temperature, track condition and driving style.

In principal, if your pressures are too low the tyres will reach a certain temperature and stabilise. This will give a very consistant and easy to drive kart but will always be below optimum performance. If they're too high you'll go past the optimum. You may only get one or two laps at optimum, after which performance will drop off very quickly. When you get them spot on your tyres will reach very close to optimum temps and pressures and you'll be quick throughout the session.

Having said that, the nature of kart frontend geometry tends to mean we overheat our front tyres regardless of pressures, hence why you'll hear talk of setting the kart up to come on early in the race or later on.
