The Tourance Exp on the front of my R1200GS had lots of cracks in it - some looked quite deep. I first noticed it after about 8,000 miles / 18 months old. I was quite concerned but my local tyre dealer said it was OK. I've just replaced it at 2 years old / 12,000 miles. It still had a lot of wear left but I'd lost confidence in the tyre.
The rear didn't have any cracks but I changed it at 8,500 miles with lots of wear left because it had a puncture.
