What I notice is that the ones with the round edge are mostly ceramic tiles... while the ones that are flat on the edges are porcelain tiles.
I may be wrong... but that's what I've been noticing whenever we visit Beaumont tiles.

Thanks for the reply. Do you know the advantage and disadvantages of both tiles?
BTW, the overhang thing has been "solved" by the builder by putting the timber beneath the overhang. Our overhand is not bearing much weight (only holding the windows box), so structurally, according to the builder is not a problem.

Definitions and descriptions of various types of tiles can be quite confusing.
Technically, porcelain tiles are ceramic tiles, but not all ceramic tiles are porcelains. Polished porcelain tiles are usually easy enough to identify, they have a smooth honed surface that is very flat, and the edges are square (sometimes with a bevelled edge). They are rectified to be very uniform in size & shape. This allows for the narrow grout joints that porcelains often have. Porcelain tiles are made from the finest clay known as kaolin clay, and are usually a more dense durable tile.
Tiles with a hard glazed surface, but with rounded edges are probably ceramic tiles. There are many, many varieties. More a matter of choice & taste which of these you like. Having narrow grout joints is a good idea, so porcelains are often a better tile.

If choose porcelains title, make sure they can be done properly, Otherwise, you can feel the sharp edge. I went to a showroom some time back, I can feel the sharp edge even I have my shoe on. So you can image if you walk on it with bare foot.

All Glazed tiles be in ceramic or glazed porcelian are all initially produced with what we call a soft edge (round). This is due to the fact that u cant press a biscuit(body) with perfectly square edge as it will ten dto chip prior to firing.
After the tile is manufactured it it sent for rectification. This is where approx 5mm is cut of the edge of the tile right around - giving you a perfectly square edge. The idea behind this is not to give u a smaller grout gap but to give you a flusher to surface grout joint similar to stone.
With polished porcelain the edges are cut and a slight bevel (aris) placed there. This is done cause when the manufacturers initally cut back and polishe the surface, the cutting head is parrallel to the surface there for it cant polished the radius edge - so its cut off.
Now I know the trend out there is big for rectified - but its not my cup of tea (and I import both). I find done properly a rectificated tile looks great, and seems to have a seamless grout transition from one tile to another. The porblem is done wrong it looks crap - vertical steps between tiles that can be felt and seen. These exposed egdes easily chip as they are a highly stressed point once cut. In badly laid wall, ive seen shadow lines cast form one tile to another.
If you are going to use rectificate here is a few points.
Try not to use on hollow walls (stud)
Walls must be re rendered and as flat and true as possible
A tiler is only as good as the quality of the tiles he lays, and its harder to hide when rectified.
For floor areas, even on new slabs (probably the worst) - sand and cement screed to ensure a flat surface
See the benefit of a soft edge (round) tile is that if the walls or floors are out the the tiler can humour the tile to follow the contour of the surface. Even if slightly out u have a round edge tansitioning onto another round edge - therefore masking the mis alignment. With rectificated you have a square edge - not as easy to hide.
Certain lines I use only come rectificated- but I make sure the client is aware of what preperation is involved.
Sorry if i Blabbed on a bit there...
