Temporary Tyre Rule Change

Karting Australia has advised its licence holders of a temporary change to the permitted wet weather tyres in the Cadet 9, Cadet 12 and KA4 classes, allowing various tyres from Vega, Dunlop, MG and Mojo to be used alongside the regulated Bridgestone.

The ruling covers all KA events, except for National Championship rounds.

The KA statement is below.

Due to freight delays caused by the Covid-19 Pandemic, there is currently a shortage of wet weather tyres used in the Cadet 9, Cadet 12 and KA4 Classes in Australia.


Please see below for the Temporary Class Rule Adjustment.

For the sake of clarity

A Cadet driver can use a set of tyres consisting of four (4) tyres of the same brand from the Wet Weather tyres listed above.  This set of tyres can consist of either:

  • Four (4) tyres as per the the sizes as listed in the Rules;
  • Four (4) ‘front’ tyres of a brand listed above; or 
  • Two (2) ‘front’ sized tyres and two (2) ‘rear’ sized tyres of a brand listed above.
