All 4 tires had been replaced since some of these pics. Front tires are 90% tread. You are correct on rear tires. Rear tires are being eaten alive every time I drive vehicle. I need to get the Toe adjusted. Its a shame , myself also being a new Humvee owner, replaced all 4 tires and had no idea why the rear tires were wearing down so quickly. .Just recently found it to be the Toe adjustment through this invaluable site. It just goes to show that no matter how much you pay for your Humvee, most likely there will be some work somewhere that needs to be addressed. As far as the rear being lowered, must be camera angle as vehicle had 1" lift added equally to front and rear.
