Ignore tile manufacturer instructions at my peril ?

[tilernot]

Hello All

So I bought these tiles from Wickes and it says in the small print on the side of the box something like "....minimum grout line 3mm....". I just put two face to face and they seem identical to me but it doesn't actually say rectified anywhere.

I'm planning to put them on the floor in the kitchen. What are my chances if I ignore the instruction and go for 2mm?

The 3mm is the standard for floors but if you want 2mm then the choice is yours 👍
