I hate it when they add the width this way to wheels and rims. The 25 probably refers to the width of the target size tire, ie.
for 700x25c tires. In that case the inside rim width is probably 13-17mm, but you have to ask to confirm.
If you're using these to replace your 27" wheels, be aware that a 700c (622) rim is 8mm smaller in diameter, so you'll be lowering the brake shoes by 4mm to match. Take a look at your brakes and confirm that you have the room.
The bike will also be 4mm lower to the ground, (with the same width tire), but this won't be an issue either way.
Lastly, if you still weigh the same as you did in the OP, consider shopping for tires nearer to 28 or 32mm, and wheels to match, with inside rim width of 17-19mm.
