It's possible that it was tow out, I can't recall exactly the alignment specs that caused this issue. It was discussed ad nauseam on the C5 forums when I had my GS. And I had to replace the fronts long before the rears. Which gave me some opportunities to do some burnouts shortly before replacement. This was an issue when I sold the car w/ low miles. The buyer who eventually bought it was initially concerned about why there was a tire replacement w/ so low miles. The broker that sold my car had to show the buyer "evidence" that this was in fact true.
From Google AI:
This is a known and common characteristic of the C5 Corvette Grand Sport (as well as the Z06) due to its specialized factory alignment
. While most rear-wheel-drive cars wear their rear tires faster, the aggressive, track-focused alignment on these high-performance models causes the front tires to wear out more quickly.
Here are the primary reasons for this front tire wear:
- Factory track alignment. The Grand Sport and Z06 models from the factory have a more aggressive alignment that is beneficial for high-performance handling and cornering on a track. This alignment typically includes a more aggressive "toe" and "camber" setting.
- Excessive negative toe. The toe setting refers to how much the tires point inward or outward when viewed from above. The factory alignment for the Grand Sport uses a negative toe, or toe-out, setting. This causes the front tires to "scrub" sideways as the car drives straight down the road, increasing wear. While great for turn-in response on a racetrack, it leads to rapid tire degradation during normal street driving.
- High negative camber. Camber is the angle at which the tires tilt inward or outward when viewed from the front of the car. Performance vehicles are set with negative camber, where the top of the tire tilts inward. While this keeps more of the tire on the road during hard cornering, it puts most of the load on the inner edge of the front tire during straight-line driving, causing accelerated wear on the inside edge.
