Poor spoke tension will cause the tires to be harder to remove.
...sounds silly perhaps, but true.
Almost all factory made wheels will come with spoke tension that is
far below optimal. Properly tensioned spokes will actually decrease
the diameter of the rim by a very small amount and, while not the
actual purpose of proper spoke tension, will allow the tire to come
Optimal spoke tension will also make your wheels as strong as
possible and keep them as true as possible.
I don't know if there are any good wheelbuilders in our local shops
as I build my own. This is very much a skill and most wheelbuilders
don't bother doing a good job. ...most of the factory stuff is done
in seconds by a machine.
I used to have to constantly re-true wheels and had a hard time
removing tires, and occasionally even broke spokes until I started to
build my own - I now run 32 spoke standard wheels (mavic open) on my
single and 36 spoke on my tandem with zero problem at about 210 pounds.
The "bible" on the topic is Jobst Bryant's "The Bicycle Wheel" - see
the site below.
