Default Front Tire Wear

Dealer says both front tires are worn on the inside, my 05 C6, to the point where they need to be replaced. Still lots of tread across the tire except for the inside. Technician says that an alignment is not necessary, this is just how C6 front tires wear. Have about 15k miles on GY EMT (non Supercar) tires. Still have about 8/32's on the remainder of the tread.

I am thinking that the alignment is off. Any thoughts?

Thanks.

I had the exact thing: Both wore on the inside edge.
Replaced the two front tires at 18K and had he realigned at a performance shop: He gave is just a little more positive camber (made the tires "stand" up just a little straighter.

The car "feels" just a little "looser", and steers a little easier at low speeds.

At 26K, the tires still look new.

Any "technician" that says an alignment isn't necessary for those conditions doesn't know crap about suspension geometry and adjustments. Take the car to someone who knows.

The wear pattern you depict is what I would expect from a performance oriented alignment. Usually some negative camber is dialed in for better allow better cornering capability.

This, in conjunction with appropriate toe settings, can really make a difference in the handling of your car. However, the price you pay is increased wear as shown/described.

Again, as you state, dialing in less negative camber will allow the tires to wear more evenly at the cost of somewhat reduced cornering performance. It's all a tradeoff.

My 05 had the factory alignment that caused this wear. I changed the alignment slightly and now it's wearing evenly.

Mine wore evenly across the width of the tread.
