Since fitting four new Bridgestone tyres to my VE Commodore earlier in the year I have travelled 15,000 km, mostly on the highway with cruise control. The front tyres are fine, but the rear tyres now need replacing as they are down to the indicator. The tyre company where I bought the tyres told me that this is a common problem with the VE. Yet my mechanic said he has never heard of this, but did however hear about cheap and nasty tyres being imported and labelled as brand name tyres. Any further insight you may be able to provide would be appreciated.
Older model Commodores did have an issue with the geometry of the rear wheels that led to rapid tyre wear, but that doesn't appear to be an issue with the VE. If the wear is uneven across the face of the tyre, if the tyre is wearing on the inner shoulder, there could be an alignment problem with your car, if the wear is even there are other issues affecting it. There is some suggestion that there are counterfeit tyres being sold here as brand name products, but you can avoid that by shopping at reputable tyre dealers.
