I got mine mounted 2 days ago, so I can't comment long term. I think I can tell visually that the tires are a little less wide than the stock 265, but that could be because I know they are. I doubt they will leak, I spent a ton of time researching this topic and 235F/255R is a very common winter size for our wheels.
What winter tire did you get in 265/40/18? I didn't find any good option in that size.
