First time post from an extremely long time (10+ yrs) lurker.
Jax Tyres are having 10% off all tyres if ordered online. Only for two days. Great if you are eyeing a set of ultra high performance tyres for your high yield investment, or if you're after tyre brands which rarely give anything more than $100 cashback (e.g. Michelin, Pirelli etc)
Edit: Bob Janes may price match and pay you 10% of the price difference (i.e. ~1% further discount).
I always get the best online quote from say tyresales.com.au and then call my local Jax quickfit. They always seem to be able to beat all advertised discount pricing.
