Would like to thank everyone for there encouraging comments on my plane. I've installed my HUGE 8.50x6 tyres the other day and couldn't resist a test fly. The 8.50's lift the hole plane up 2" so getting into the cockpit you have to lift your but a little higher, this gives a lot more visibility over the nose while taxiing. I have let the front tyre down flat and measured between the prop and ground which I still have 4" of clearance so I'm happy with that. Ground handling is superb, it is a little smoother while taxiing over rougher ground as the tyres soak up the bumps. In the air you can not tell the difference in handling, other than a loss of 2-3 knots of air speed. Here are a couple of photos.
