Subaru WRX STI Tyre Guide Malaysia
The WRX STI VA runs 245/40R18 tyres on OEM fitment. Due to the Symmetrical AWD system, all four tyres must be the same brand, model, and size — mixing tyre brands or sizes stresses the DCCD and centre differential. In Malaysia, ultra-high-performance tyres rated for the STI's weight and power (Michelin Pilot Sport, Bridgestone Potenza, Continental SportContact) are recommended. Replace all four simultaneously when worn.
