Extra support for tiling kitchen

Hi
I am installing tiles in my kitchen and someone just mentioned that make sure you have extra support for tiles in the flooring. I went to my basement and checked kitchen and dinette floor and don't see any extra support so was wondering what kind of extra support I need because definitely I am putting lot of weight by adding 12x24 porcelain tiles over 10x10 kitchen and 8x8 dinette area.
any guidance will be helpful.

Tell us what size and free spans the floor joist are.
What's there for sub flooring and under layment?
That floor need to be dead flat and no deflection for tiles that size.

My joist are 14 5/8 inch apart. I am not sure about subfloor as there is old wood flooring right now.
does that make sense.

It makes sense but we need a lot more information to know whether the structure you have is sufficient for tile.

Let's start here - what is the size and unsupported span of the floor joists? You provided the spacing but we need more.

Additionally, do you have any vents in your floor for heat or AC?
