Hello bardwelllauren,
They are correct, Never drive with tires that have different tread patterns in any AWD vehicle. The problem is that if the front and rear tires are different , then the front and rear axles are always turning at different speeds. Even when the car is going straight ahead. That means the center differential is always working -- and that wears it out. And Remember the center differential costs big money.Take the service manager's advice and replace all four tires at once.
The best use of tires is to buy 4 new ones, and rotate them on a regular interval, so they wear evenly, and you get the most mileage out of them. Most of us forget to do this, and 2 of the tires wear out before the other 2 do.
