Having a look around my local DIY place there's the choice of P4 and
P5 chipboard, OSB3, plywood and structural plywood. They're all 18 mm
width and can all be used for flooring but, which is the best to use
to tile onto? To me the obvious answer is the one that has the least
expansion change between hot and cold conditions to minimise the
chance of the grout cracking. Does anyone know which is the best
please? Oh, and if you have a recommendation for the type of adhesive
and grout to use that would be helpful too. Thanks.
Not sure on the wood front but I think you need to use flexible adhesive
when tiling onto wood for the exact reasons you mention regarding movement.
Probably best paying a visit to your local tile shop and asking them. Or,
have a look on this DIY forum

Personally, I would not touch chipboard or OSB in a month of Sundays
if it was on the Ground floor
First floor has much less risk.
I agree with the post re the adhesive as that is key
If I were doing this I would go for the best ply possible
First of all wood is a terrible thing to lay ceramic tile on to. I
don't know what you'll use in England however in the states we use
cement board or hardibacker. In the us it comes in 1/2 & 1/4 inch.
You have to use this on top of the wood.
This stop expansion and such if applied correctly.
