Hi I moved in to a recently renovated home one year ago. The kitchen had new ceramic tiles installed, with sanded grouted filled in the 5/8 inch joints. I sealed the grout after moving in as I was told...
I have a similar problem. My builder used dimensional lumber for the joists. I asked him if thet would be sufficiently stiff for tile floors, and he said yes. Then after the cracks started, I asked him why the cracks, but he said he didn't know why. It's not necessarily the subfloor but the combination of joists, subfloor, and concrete backer boards under the tile. If you can access the joists under the floor, perhaps you can reinforce them with additional joists or stiffeners before regrouting.
As for me, I have done neither so far. Wife has not complained, so I spend my spare time helping people on FixYa. Like you, I fear regrouting will just lead to recracking, and I no longer have access to the joists. :o(
By the way, your question was sorted as a Harley Davidson question. You weren't riding you bike in the kitchen, were you?
