Greg, if your
tires and wheels are fitted that closely, you may have
trouble with them retracting during a normal takeoff. The
tires "grow" in diameter when they are spinning, and take a bit more
clearance than when they are static. Side clearance should be correspondingly
increased just a bit, but a number of the -IV drivers have had to rework the
door openings to accommodate the fact that the wheels/gear is also distorted
just a bit by air loads and can hang up on the sides as well.
Some folks
tap the brakes to stop the wheels before retracting them, but there are several
reasons why this is not a good idea--the principal one being that on very rare
occasions, the brake pads and/or hydraulic cylinders will stick
in the "brake applied" position when you do this. It makes for a
nasty surprise upon the next touchdown...
