John,
I am wondering if your undercarriage frame is perfectly square to the
centreline of the aircraft.
I would firstly do the following check :-
Assuming your fuselage is in a jig and level both ways especially across
ways, mark a centre line on the floor by dropping a Plumb Bob down from the
Cross Hatch marks at the front and rear of the bottom of the fuselage and
marking these positions on the floor. Using these marks as the reference
and a chalk string line, mark the projected centreline on the floor. Now
lower your undercarriage to see if the centre of the tyre aligns with the
marked centreline.
If it doesn't, I'd suggest you seek help from Andy.
If it does, then there is one other thing I can suggest assuming you have a
Carlisle Tyre supplied by Europa. Purchase a 700 X 6 X 4ply Condor aircraft
tyre. Remarkably, this tyre is actually 15mm BIGGER in diameter than the
800 X 6 Carlisle and more importantly, 20 mm narrower. This tyre is also
much firmer in the walls, stands up better and as well as giving better
clearance on the brake master cylinder, gives much better clearance on the
brake caliper.
Hope this helps and good luck.
