Ancient tyres compromised Wilson Security Racing at Hidden Valley Raceway today but luckily David Wall has team-mates Jason Bright and Fabian Coulthard to rely on.

Wall spent most of the four 30-minute practice sessions on used hard-compound tyres before bolting on a set of softer compound tyres in the final outing.

The faster soft tyres were left over from the Gold Coast round in October last year, however, and were not up to the challenge in today's sweltering conditions.

Wall ended 28th fastest but will rely on the set-up information from his team-mates for tomorrow's qualifying at 11am.

"We just didn't know what to look at because the tyres were obviously from Indy last year; they were nine months old so we can't read too much into them.

"We're mainly going off what we learned from the hards all day but, in general, putting soft tyres on dulls the front of the car a little so you'd have to change the set-up to adjust for that.

"Fortunately we're not that far away from my team-mates on the hard set-up so we can see how they managed the change to soft tyres. They're both in the top ten so it should be a good bench mark."
