In my experience the wear on the inside of a tire is referred to camber, this term is relative to your vehicle being misalligned. I suggest you visit a local service that can offer you an inspection on your alighnment. You may find that after an alighnment is performed and your tires (if not exciessively worn) can be rotated to the back you can maintain the integrity of your tires.
The tires on your car are like the shoes on your feet. They are a great indication of how your car is driving (and how a person walks, take a look at the soles of your shoes)
When your tire is wearing out along the inside of the tread, that is an indication you need a wheel alignment. Your tire for some reason is leaning too much on the inside (that's called camber) and is putting too much weight on one side of the tire. There is excessive camber in the front suspension, causing the wheel to lean too much to the inside or outside and putting too much load on one side of the tire. My question to you, is why. Sometimes a wheel alignment will cure this problem. Other times there is a front end component that is causing it. Before you have the alignment done, make sure to have the front end checked on your car.

It*s an alignment issue. Have the front end aligned.

Your Cadillac could just be out of Alignment or could have a worn Front End Part. This may be a safety issue, please take it to a service shop that has Alignment equipment to have your Front End and Tires inspected!

Hello Margaret- This is most likely an alignment issue*toe-out as well as incorrect camber adjustment are the likely problems. Any competent alignment shop can fix this. Hope this helps*Super Girls Auto
