Hey mate. We bought the Warrior 3 weeks ago. It comes with 295/70/18 Geolandar tyres. Premcar has modified the towbar (std on the Warrior) to fit the 295 tyre. We also had the 3999kg pre rego DMW GVM upgrade which also doesn't require a wheel upgrade...only 4.2kg Apex or 4499kg DMW requires the 1500kg wheel upgrade. We did put ROH Crawler wheels on it but not for the GVM requirements. Strange that the spare wheel carrier fits the ROH on the Warrior. I didn't need the aluminium ring you got from Aaron. I have noticed though that the spare has come loose twice and dropped a little..
