V8 Supercars has pulled the pin on a tyre test that was due to take place following this month’s Winton Super Sprint.
The category and control supplier Dunlop had been slated to run a new construction and soft compound at the rural Victorian venue following the May 20-22 race meeting.
While the tyres are understood to have already arrived in the country, V8 Supercars has cancelled the day due to concerns over the suitability of the recently resurfaced circuit for tyre testing.
The decision was made following last month’s private test day for the Holden Racing Team, Team 18, Garry Rogers Motorsport and Nissan Motorsport that saw teams report negligible degradation due to the grippy surface.
Prodrive and the HRT had both agreed to supply a car and driver for the planned tyre evaluation.
It is expected that V8 Supercars will reschedule the test for later in the season in order to assess its options ahead of 2017.
If the new rubber is introduced, it will mark the first construction change for the category since the 2013 introduction of the Car of the Future, which saw a move to 18-inch wheels and tyres.
As previously reported, the new construction has been designed to improve driveability and driver confidence in an effort to create better racing.
The category continues to use a single construction for both steer and drive in order to minimise costs for teams.
V8 Supercars and Dunlop both declined to comment on plans for rescheduling the tyre test when approached by Speedcafe.com.
