I've had 3 already replaced by a tyre shop who cracked them after I cracked the 4th trying to replace a flat. I'm now waiting for Castle Hill Toyota to get 4 new ones in as they stuffed all 4 doing a wheel balance and puncture repair. Bad news is about $95 each...... The really annoying thing is "they've" damaged the alloys removing the @&$!ing things in the first place....at least I've had success getting them replaced. I'd hate to have to pay for it myself when it's obviously a defect.
