Anyone having issue's with your tires? I have 34,000 on mine and had it in for oil change and they found that my front tires were coming apart. The belts are showing all the way around the inside edge of the front tires. They are ready to seperate, some of you folks might want to check the inside edge of yours.

34,000 miles seems like an awful lot of miles for that tire.  Don't know how they made it that far. 

Most likely alignment issues. Corvettes are notorious for alignment issues from the factory (or so I have read).

have the camber set as close to "0" as posible at alignment shop. stock setting is for high speed handling but if you do a lot of open road driving the tires will wear out on the inside edges. i learned this on my 97 and when talking to a corvette engineer at carlisle he told me the change the camber setting

Goodyear front tire was faulty and wore out at 12,000 Miles. Alignment was fine. I've had trouble with Goodyear tires on new GM products for years, short life, noise and uneven wear.  I have not bought a aftermarket Goodyear tire for over twenty years due problems with OEM tires including Corvette. I use other manufactures tires and they handle better (over 1G on the 2006 Z51 Corvette) wear longer, less tire noise and vibration not related to balance. 

Wheel alignment is set to allow easier handling (corners / curves) at speed (highway and otherwise).  This is not uncommon for many high end marques, and high performance vehicles.  That being said, I also concur ... 30,000+ miles is a birthday AND anniversary present wrapped in one.  I have 18K miles ... tread is at 3/32 (1 tire), and 4/32 (3 tires).  I believe my tires came with 9/32 tread ... so that means 5/32 have been utilized over 18,000 miles.  ZR rated tires generally do not offer a longevity warranty, since they are considered high performance tires, and as such, are expected to see spirited driving habits.

Personally, I like Michelin's on my German sedans.  When I have to replace the Goodyears, I will likely consider Goodyear (not runflats), or Michelins.  Corvette Racing switched over to Michelins a while ago ... perhaps it is a financial sponsorship move ... but I am willing to consider changing to a manufacturer with which I already have good experience.

Wow! Thats great mileage for a set of run-flats. I got 18,000 miles on  original Goodyears. Replaced with Michelin, will see how they last, with a 500 treadwear rating vs the OEM Goodyears with a 300 rating.

I had to replace the front tires on my "11" Grand Sport after 10,000 miles, inside edges were worn badly.  Factory alignment was inaccurate.  Had a four wheel alignment done when I replaced the fronts.  The rear tires need replacing now after 13,000 miles.  Again the same problem with the inside edges wearing badly. 

I changed mine at 21,000 should have been done at 18,000.... Put a set of Hankooks on not run flats but they ride great check them every year have 10,000 miles look brand new use the old run flats and original rims  for winter storage
