I noticed while changing different wheelsets on my bicycles, that some of them are larger than the others.

Case one:
Tires are Schwalbe Lugano 700x23
Unknown 700c rims laced to Shimano 600 hubs. Low profile, probably typical mid 80s clincher rims.

Switching the same tires to Mavic CXP33 rims laced to Shimano 600 6500hubs, I noticed that my rear wheel cannot fit into the rear triangle while the tire is fully inflated, so I have to insert the wheel and then inflate the tire to proper pressure. Also, I had to lower the brake pads, farther from the edge of the tire, since the brake pads won't fit the same position and would rub the tire.

Case two:
Tires are Vittoria Rubino 700x25

The same Mavic CXP33, but I had the front wheel re laced with Remerx Taurus, and now I notice that the top tube on my non sloped steel bicycle is not parallel with the ground anymore. Also, I had to move the brakepads all the way within the short reach of the brake calipers.

So, while using same tires, I noticed the complete wheel size actually does change depending on the rim.

Bead seat diameter is standardized 622mm, right?
So the tire should fit on all rims the same, though inner width of the rim surely dictates the height of the tire in the end! Too bad I did not have info about the inner rim width of the unknown rims from the start of the story, but it does make sense that with smaller inner rim width, the clincher is deforming verticaly. Is this really the case? Mavic's have ETRTO 622x15 and Remerx's have 622x14. Does that 1mm tighter space really increases the vertical size of the tire?

I will relace the rear wheel to the same type of Remerx rim, and if the bicycle does not level the top tube, I'll suspect at the bent fork

Anybody care to share some practical knowledge regarding this topic? I'm having difficulties searching anything related to it.

Thanks

All ERTRO 622mm rims are roughly the same size (there may be slight differences, but they're very slight), but rim width can vary, and that can affect final tire size.

Even on seemingly identical rims from different makers, there can be differences in the brake track position. Some machined side rims have the track moved down a bit so the brakes rub closer to where the rim is bridged than at the tips of the tire flange. This is a better position, and if you have a choice may want to move the shoes down for all rims, but that's at your discretion on most rims.

Other than that, final height of rims in the frame or brake shoes can be affected by axle end diameter, and/or a slightly bent axle, but I've never seen any that were different enough to cause me to move brake shoes.

Lastly, changes in rim width can also affect brake shoe height, especially with canti's because the shoe moves in an arc. Canti's move down as they come in, most side pulls tend to move up (but much more slightly).
