I was checking out my front tires yesterday and i noticed they are both wearing on the inside. I have 13k miles on my car and I can already feel the steel belt on one of the tires. Anyone else experience this?
Like I told someone else on another thread asking about tire wear, our cars run a pretty aggressive amount of negative camber from the factory. I don't remember the exact measurements, but it's several degrees of negative. With 13K miles on those tires, I'm not overly surprised you're seeing wear to that point. My buddy has a C7 and he had the same tire wear you're describing after around 13K miles despite the fact his car has less camber. Soft tire compound+aggressive negative camber=rapid tire wear. Be grateful you don't have an R, because they chew through cup 2s in about 3K miles of street driving lol.
The car ends up at around -2.0 degrees Camber, which isn’t bad if you Performance corner the car. Adds better grip under power. Overall treadwear gets better after the tires have been seasoned on a track day. Rubber seems harder. I would never go 5,000 miles without an alignment check though. Toe settings do more wear and they are measured thinner than a dime, most chuckholes will do that it.
Have a bolt (unrepairable) in my rear tire so I'm getting two new tires. While up on the rack I noticed both rears are wearing on the OUTSIDE as if it has positive camber. I'm wondering if I should tell them to add a click or two of negative?
